Optical expert addresses the Sony full-frame SLR question

Tuesday, October 23rd, 2007

Last week, I posted about the alleged difficulty of using a full-frame sensor with the Sony/Minolta anti-shake system. See the post: Can Sony build a true full frame dSLR? I made critical error in my post, when I suggested that the sensor had room to move up and down but not side to side. This is incorrect. The typical 35mm image circle only needs to cover the full-frame sensor from corner to corner, so there would be no room to move the sensor in either direction.

So I was mistaken, but sometimes mistakes can be a positive thing. My error encouraged Bert Pasquale, an optical engineer (and Sony/Minolta SLR user) to write me with his assessment of the full-frame, anti-shake situation. In addition to pointing out my little misconception, he has several innovative ideas on how Sony could deal with the problem.

I asked Mr. Pasquale for permission to reprint his comments and he readily agreed. His remarks follow:

Hey Tom,

Bert Pasquale here, nicetameetcha! 7D & A100 owner… but not for long — the A700 is in stock in my local store since last week, and all the online dealers have them. (Sidebar: Beware ANY low-ball online dealer! - Be sure to Google any potential dealer for reviews before purchasing.)

About full-frame & sensor anti-shake: Note that you get clipping moving either vertical or horizontal; the image circle intersects the corner of 3:2 image rectangle. (Which does make the vertical less sensitive, and luckily that’s the typical hand-held motion.)

But how much movement does a sensor typically need during an exposure? Let’s say a “full-frame” image needed to be stabilized +/-1mm outside the 43.26 mm circle (the diameter of the image circle surrounding a 24×36mm film rectangle) That’s a +/-2.3% shake allowance. (Note: I don’t know how much the current mechanism even allows.)

Let’s think about how much image movement is typically introduced in an exposure? Assuming equal shake, it’s proportional to the focal length. (Of course for short exposures, it’s also proportional to the time.) Taking a few test shots at 1 second at 200mm, I am not shaking more than 1% total of the measured frame. That translates to only 0.42 mm of shift. Even if this was drift in just one direction, I’m still within a reasonable clearance, and if it’s vertical, even less of the image is potentially affected. So, fear not for your ultra-wide angles not working with full-frame sensor-based AS — You would have <<1% shake.

So, what are the implications if you DO move the sensor out of this circle? SLR lenses do not just fall off to zero throughput at Image Radius = 21.63 mm. Though each lens has it’s own characteristics, vignetting often begins before then, and continues out a few mm beyond before reaching zero throughput. (This is especially true when using a near wide-open aperture.) So the final implication of sensor-based AS is this: Some portion of some corners could be somewhat more vignetted than w/o AS. If we were talking about film, this might be an issue, but this is digital imaging, Baby!

What are the solutions digital imaging offers? Here a few:

  • Option 1: The camera could, hypothetically, apply an appropriate amount of gain to the corners that went out of the circle to try to make up for lost luminance. It could very intelligently combine general knowledge (Lens ID, focal length and f/# info) and individual frame measurements to compensate. Or, a manual in-camera or computer software user interface could be given. (If the camera embedded the shift info for each corner, and the user could apply the supplied or manual falloff curve correction. (You can already do this in Photoshop manually, as you do for existing “symmetric” vignetting correction.) It would be great to have lens correction built into the capture, anyway (a-la-DxO or the sort.)
  • Option 2: The camera could “warn” that possible excessive vignetting occurred, and give the user the option to crop the file right in the camera (manually or automatically), or in software on the computer. Before you even pull the trigger, the camera could observe your stability and let you know the frame is going to be clipped or not so you could frame appropriately, or become more stable. (This would be sweet!)
  • Option 3: Limit the AS movement. A user option for given situations could beep, flash or just not move beyond a certain amount, unless willing to crop.

These could be combined to make the AS sensor vignetting issue almost a non-issue. The competition would continue to point out the “superiority of lens AS” (while failing to mention the cost) and Sony will get beat up on discussion boards by people who don’t even have a portfolio. However, the majority of images would be fine — most AS movement would be a fraction of a mm and the corners would show minimal additional falloff. Notice that no one is complaining that the APS-C lenses made by Sigma and Tamron are hopelessly useless on a sensor-stabilized A100. I hope this discussion is helpful.

As an aside: If the “full-frame” sensor used the same pixel size as the A700 (5.3 micron), it would be about a 28.8 effective Mpixel sensor. If it had a 1.1 crop factor (32.7×21.8mm), it would only be 23.8 Mpixels. (If it used the A100’s 6 micron pixels, well, it would only be 23.5 full / 19.5 cropped Mpixels…) (If it used the Canon EOS-1Ds Mark III’s 6.4 micron pixels, it would be 21.0 full / 17.3 cropped Mpixels.)

Bert Pasquale
Optical Engineer

Thanks for sharing your knowledge, Bert. This is exciting stuff! In camera, computer controlled gain? Falloff curve corrections. Sensor based warning that the stability could cause vignetting! Wonder how much of this Sony has considered — and more importantly how much they will actually implement in the Alpha flagship camera. Stick around. it looks like things are going to get really interesting. It looks like its a great time to be a Sony A-mount user!

Can Sony build a true full frame dSLR?

Friday, October 19th, 2007

Can Sony really make a full-frame dSLR? Not will Sony…but CAN Sony really do it?

Some months back, I wrote that I expected the so-called “flagship” Sony Alpha (possibly named the A900?) to carry a full-frame sensor. I still believe that to be true, however I’m hedging my bets a little. It will be “almost” full-frame or “close” to full-frame. It may not be the actual size of a 35mm negative, however, which is the definition of a full-frame dSLR to most photographers.

It isn’t that Sony lacks the technology to build an actual full-frame sensor. Sony has the ability to build just about any sensor they could wish.

Super Steady Shot doesn’t play well with a full frame sensor

The problem is the Super Steady Shot (anti-shake) system. Not that there is anything wrong with SSS itself, the in-body image stabilization is one of the Sony Alpha dSLR’s major advantages. However, one of the Alpha’s other major advantages is that it can use the extensive line of Minolta A-mount autofocus lenses. And thereby hangs a tale.

Twenty-some years ago, when Minolta engineers were designing the original A mount glass, there were no digital SLRs and no anti-shake systems. Thus, there was no reason to design a lens to cover anything other than the standard 35mm film image.

Thus the AF A mount lenses were designed to project a circle that would encompass a 24 X 36mm area at the camera’s film plane. There was no need to cover a larger film plane, because no Minolta SLR offered a larger negative size.

Maxxum 7D and Antishake: no worries

When Konica Minolta engineers developed the Maxxum 7D, they designed an in-body anti-shake system. The system works by moving the camera’s sensor in relation to camera movement. In essence, if there is camera vibration, the sensor stays in one place, despite the lens and body movement. The same system is used in the Maxxum 5D, the Sony Alpha A100 and the Alpha A700. All of these dSLRs use a 17 X 23mm APS-C sensor.

See the problem? If Sony develops a 24 X 36mm full frame sensor, any lens will need to cover an area larger than 36mm — at least when SSS is turned on. If vibration occurs in an up and down motion, there is room for the sensor to move in relation. If, however, the sensor moves to the left or right, it could move outside of the area covered by the lens. Update: I was in error about room for up and down motion. See these remarks by an optical engineer to understand why the image would be clipped in any direction the sensor moves.

This isn’t an issue with the current Sony/Minolta dSLRs, since the smaller APS-C sensor has plenty of room to move in any direction without moving outside of the lens coverage. When you move up to a full frame sensor, however, there isn’t nearly as much breathing room.

Lens coverage varies

Of course lenses vary. Some of the existing Sony/Minolta lenses may offer enough coverage to allow the SSS system to move — but others would probably exhibit some vignetting if the sensor moves too far to the left or right. Who wants to drop a ton of cash on a professional dSLR when many (most?) of the available lenses might display some vignetting?

How will Sony handle the full frame design?

Sony can tackle this problem in a number of ways. The first could be to drop SSS for the flagship model. That makes little sense, since Sony would then have to develop a line of image stabilized lenses. If they are going to develop an entirely new lens line, they might as well design larger coverage lenses and retain the in-body image stabilization.

Neither of these options are very credible, however. As I said, one of the Sony Alpha’s major selling points is that you can use those millions of Minolta A-mount lenses. Start redesigning the lenses and there is far less reason to choose the Alpha over the competition.

The rumor sites are suggesting that Sony could eliminate any vignetting problem by reducing the sensor size. The sensor could still be much larger than the current 1.5 crop sensor, but not exactly the size of a 35mm film negative. The figure bandied about is 1.1 crop. That would indicate a sensor of something like 21.6 X 32.4mm.

I want my super wide angle lens back!

Loosing 3mm on the width and 2.5mm on the height doesn’t seem like a lot — but it will affect the camera’s ability to display the widest angle of view with current lenses. One of the biggest problems with the APS-C sensor is that most of the original A-mount wide angle lenses aren’t very wide any longer. Cropping a 35mm lens to APS-C size yields something equivalent to the “standard” 50mm lens on a full frame camera. A 24mm lens is now closer to a 35mm. Even a 16mm fisheye is will only show what you would see with a 24mm lens on a full frame camera.

So one of the prime reasons for choosing a full frame camera is to make all those Minolta wide angles truly wide again. A 1.1 crop would be much better than a 1.5 crop in this regard — but is it enough? That 16mm would now be equivalent to 17.6. A 35mm would look like a 38.5 lens.

Those differences seem fairly insignificant, but there are times when you need the widest angle of view you can get. I hate to give up even a millimeter when I am working with an extreme wide angle.

There is one other option that Sony could adopt. Create a full frame 24mm X 36mm sensor and allow the camera to use the full sensor only when SSS is turned off. Turning on the image stabilization would automatically turn off the outer ten percent of the sensor. This would give the best of both worlds. When SSS is engaged, the sensor size is reduced so there is no chance of movement causing vignetting. Turn the image stabilization off and you get the entire full frame area and the ability to shoot at your lenses widest field of view.

Taking a page from Nikon’s book?

This isn’t as far fetched as it seems. Until recently, Nikon didn’t have any full frame cameras in it’s line up, and they sold a ton of APS-C type lenses to go with their 1.5 crop dSLRs. With their all new full-frame D3, Nikon users who owned a bag full of 1.5 crop lenses faced a big problem. “Big N” sidestepped the issue of the APS-C lenses not covering the FF sensor with a switch that reduces the sensor to APS-C size when shooting with a 1.5 crop lens.

Sony could do the exact same thing with their offering, simply reducing the sensor to 90% when SSS is turned on. Of course to be truly useful, there would need to be some way of indicating the crop area in the view finder. This would probably be in the form of engraved lines on the ground-glass to show the crop area.

Would this be worth it? I’m not sure it would be worth the trouble and cost — but it would sure be slick.

If you were on the Sony design team, how would you handle this issue?

Senior Sony Alpha manager interviewed at hardwarezone.com

Sunday, October 14th, 2007

Very interesting article on the hardwarezone.com website. Timothy Fernandez interviews Mr. Keiichi Ishizuka, Deputy Senior General Manager - AMC (Alpha Mount Camera) Division at Sony.

The article is well worth a read, if only for an insight into Sony’s plans for the near term and the future. It also provides an insider’s look into the design process behind the A700.

Although Mr. Ishizuka is somewhat careful not to reveal too much info about what is in the Sony pipeline, he does say that the flagship model ( the rumor sites are calling it the A900, but Ishizuka gives no confirmation of this ) is on track for next year. He also says that Sony is indeed developing a replacement for the A100 and hints that Sony may offer other new models — without saying when such models might be announced.

The bulk of the article discusses the new A700 and the design considerations behind it. Mr. Ishizuka cites picture quality as the top feature of the A700, and also mentions the engineering behind the Alpha A700 dSLR’s shutter and vertical grip. Ishizuka also takes Fernandez on an in-depth look at the A700’s new DRO option.

I expected the DRO to be a great feature. Having read Ishizuka’s comments, I am very excited about trying it out.

If you are a A-mount shooter (Mr. Ishizuka refers to it as the Alpha Mount), you should take the time to read the interview. Whether you are thinking of buying an A700, or you are concerned about Sony’s future plans in the dSLR arena, I think you find the interview very enlightening.

Free Tamron 18-250mm lens to Digital Scrapbooking winner

Friday, October 12th, 2007

The good folks at Tamron sent word that they have partnered with an outfit called Triscape to sponsor Digital Scrapbooking Day on November 3, 2007. Top prize is one of the all new Tamron AF18-250mm Di II All-In-One Zoom Lenses. If you’re curious about Digital Scrapbooking day, you can check out www.DigitalScrapbookingDay.com.

The good news, however, is that you don’t have to actually create a scrapbooking project to win. Apparently, there will be a straight drawing to determine the winner of the lens. All you have to do is send an e-mail to Tamron between now and December 10. It doesn’t get much easier than that.

If you are interested, click on over to:
http://www.tamron.com/lenses/digital_scrapbook07.asp and fill out your name and e-mail address.

Here are the rules from the Tamron site:


  • No purchase necessary.
  • One entry per email address.
  • Employees and family of F+W Publications and Tamron USA, Inc. are not eligible to enter.
  • Entries must be received by midnight 12/10/07 to qualify. Winner will be selected randomly from all entries and notified by 12/12/07 via email. If there is no response from the winner by 12/19/07 we will choose a new winner who in turn will have 5 business days to respond.

  • Void where prohibited by law.

The Di II All-In-One Zoom Lens is designed for APSC sensor digital cameras and is available in Nikon, Canon, Pentax and Sony mounts. I didn’t see anything about winner’s choice, but I assume whoever sends in the winning entry will be able to select which lens mount they want. No mention on the Tamron site that this lens is compatible with older Minolta dSLRs (7D, 5D), but if you choose the A-mount lens, I would think it would work with Minolta as well. Check with Tamron to be sure.

The 18-250 AF lens only weighs 15oz. and lists for $499. You can read more about it at www.tamron.com/lenses/prod/18250_diII.asp. I might just be willing to give up my e-mail address for a chance at winning one of these.

If you follow through and actually win the lens, be sure to let us know. I’m sure your fellow Alphatracks readers would like to congratulate you!

Sony A700 sample images starting to appear online

Saturday, September 22nd, 2007

The Imaging-Resource website has just posted a number of A700 sample images. In addition to images shot in all manner of lighting conditions and ISO ranges, Imaging Resource offers something called the Comparometer™ a web application that allows you to compare images from any two cameras in their data base against each other.

Normally, I’m not a big fan of online image samples, because each computer monitor is different and one photographer may shoot a little differently than I would. So I prefer to make my own tests, since the information will more valid for my type of shooting and my hardware. But this is the A700 were talking about. Since I haven’t gotten my hands on the camera as yet, I plan to go through the images and glean how well Sony has done their image quality homework.

I’m sure many more sites will be offering Sony A700 evaluation images in the near future. If you’ve found some interesting demo images from the Alpha A700 SLR, be sure to drop me a line (or leave a comment.) Let’s try to assemble some good resources for evaluating A700 image quality.

Are the Sony A700 controls professional grade?

Tuesday, September 18th, 2007

You can’t always get what you want…but (sometimes) you get what you need.

When Sony first announced they were entering the DSLR market, there were a lot of blowhards… ah, strongly opinionated folks, who predicted that Sony would fall flat on their face. Sony was an electronics company, they didn’t know anything about photography (despite the fact that Sony has been among the top producers of still and video digital cameras for years). Sony would, they insisted, produce a bunch of mass-market crud that might appeal to people who didn’t know any better, but would drive true photographers away screaming.

Sony A700 control layout

A place for everything and everything in it’s place…control layout of the Sony Alpha dSLR A700 photo courtesy of Sony

It didn’t work out that way, and if the early A700 reports are any indication, those strongly opinionated folks are set to eat a big helping of crow. That crow meat must be pretty bitter, because the “Sony won’t build a quality dSLR” crowd is scrambling to find a way to avoid a steady diet of field birds for the foreseeable future.

They have a problem. Unless the A700 has some deep, unforeseen flaw we know nothing about, Sony hasn’t left them much room for complaining. As I said before, the A700 appears as good or better than anything in it’s class.

So how does one save his or her reputation if you publicly predicted that nothing good could come out of Sony’s acquisition of Konica-Minolta’s SLR camera business? Simple. You make up non-issues. Such as the uncertainty over the A700’s lack of a second function dial.

To be honest, I was a little concerned over this myself.

Maxxum 7D set the standard

Konica-Minolta raised he bar when they introduced the Maxxum 7D. No other digital SLR, before or since, has offered photographers the wealth of manual controls available on the 7D. All cameras have flaws and limitations and the 7D had it’s share. But a lack of manual controls wasn’t one of them. The Maxxum 7D simply stood head and shoulders above any other dSLR in that category.

A number of Minolta A-mount users were eagerly awaiting a Maxxum 9D version. They were hoping for an advanced version of the 7D, while retaining all the manual control goodness of the original.

It was not to be. Minolta’s camera business expired before the fabled 9D could become a reality, and Sony’s first dSLR offering simply didn’t boast the manual controls of the 7D.

Some 18 months later, Sony has introduced their second dSLR. It looks to be a wonderful camera. But a Maxxum 9D it is not. There is only a single dial on the top of the Alpha A700 dSLR. The lack of a second dial is the ammunition the Sony bashers are attempting to use to save a little face. Problem is, those that have actually used the camera have universally praised the camera’s controls. Who are you going to believe? Those who have had a axe to grind against Sony’s SLR from day one or those journalists who have actually used the camera in the field? I’ll take the word of the latter, thank you very much.

So what’s so bad about a menu on a dSLR?

Let’s look at the problem. Camera makers prefer menus to dials, knobs and switches, because menus are far cheaper. It’s really just software and you can program a menu to do just about anything. In contrast, knobs and switches have to be designed, produced and stockpiled. Run short of a vital button or dial and you can’t produce more cameras until new parts are collected.

Photographers, on the other hand, prefer buttons and knobs because it is usually quicker to adjust a physical control then to scroll through a series of menus hoping to remember where the one you want is hidden.

The problem with menu driven controls:

  • It is hard to find seldom used settings
  • Requires the photographer memorize where settings are located
  • Slower to scroll and engage specific menu items
  • Difficult to change menus when on a tripod without moving camera
  • Tough to use when wearing gloves, etc.

Of course knobs, dials and switches have their own problems:

  • With a knob or switch it is easy to change settings by bumping or nudging
  • To make knobs safer, camera makers often resort to a detent or lock, which in turn can make it difficult to change settings
  • There is no “reset to normal” with manual controls. With a menu control system you can usually reset everything to a normal, default state. With manual controls you have to remember to reset each control manually.

We won’t know what the A700’s controls are like to use until the camera is in wide use. Still, I am excited that those who have used the pre-release camera have pronounced the controls as excellent.

Three inch LCD offers more room for menus.

First off, the large 3 inch display offers more room to offer easy-to-use, simple menus. With smaller displays, camera makers had to resort to grouping menus in numerous modes. This is one of the objection to menus, because you had to find the right mode for the menu choice you wanted. On some cameras, you have to set the knob to a particular setting before you can reach a particular mode. So not only do you have to remember which mode you need to achieve a setting, you have to remember which knob setting will allow you to select a particular mode. Madness!

A larger LCD provides more real estate, so menus can be organized more succinctly. There is less need to switch between modes and settings, allowing the user to find a particular menu setting more easily.

Rotating LCD helps menu clutter

I saw at least one forum where a guy was mouthing-off and making fun of the rotating LCD view on the A700. He implied it was some sort of fluff marketing gimmick that was not all that useful. I disagree. If you are shooting with a vertical grip, you pull the camera away from your eye and glance at the LCD. Having the information presented in the correct orientation is a great feature. Otherwise you have to turn the camera ninety degrees, cock your head sideways or attempt to interpret the screen at the wrong orientation. I think the A700’s rotating display is a great asset and should go a long way to eliminate menu confusion.

Knobs? We don’t need no stinkin’ knobs!

Let us not forget that Sony has found space for a number of buttons and switches in addition to the main knob. The A700 isn’t one of those toy SLRs that look like a 1/4 scale model of real 35mm SLR. The somewhat larger body means there is room for many switches and buttons, which can take the place of that second dial. Many of the most important settings (white balance, auto/manual focus, anti-shake, etc. ) are available with just a button click.

Interestingly enough, as I write this, I happened to notice my old Maxxum 7000 sitting on my desk. It was considered revolutionary in it’s day, not only because of it’s advanced auto focus system but because of all the electronic features Minolta stuffed into the camera body. Guess what? There isn’t a single knob or dial anywhere on the Maxxum 7000. Everything is controlled with buttons, slide switches or rocker switches.

Hmm…if the Maxxum 7000 could gain a reputation as one of the top film SLRs of all time with out any knobs, I’m guessing the A700 should do just fine. I’m willing to give the benefit of the doubt to those who have actually used the camera in preference to those who are complaining without having seen the camera, much less used it.

You know who you are. You haven’t used the A700, but you’re out in the forums complaining about the lack of that second dial. What sort of side dish do you want with your entree of raw crow?

Agree? Disagree? Let me know what you think!

Got an Alpha A100? These guys want your help

Help discover DRO secrets

Interesting thread on the DPreview Sony SLR talk forum. Seems some of the forum members are casting around for a method to create a new software plugin that would allow users to edit DRO photographic images in Photoshop.

DRO is the Dynamic Range Optimizer used by the Sony Alpha A100 camera. We are expecting an enhanced version in the new Alpha 700 dSLR. Similar to an in-camera HDR tool, DRO attempts to allow the camera to display a much greater dynamic range. Thus in contrasty lighting conditions, your image can show more details in the shadows without blowing out the highlights.

DRO differs from HDR in that it is done in-camera, while HDR images are created in computer. With HDR you take a series of bracketed exposures then use software to combine the best exposed areas of each bracketed shot into a single image. Sometimes the images are hokey looking, but done correctly they can be stunning.

Looking for a few good Sony Alpha A100 owners

The original poster of the thread is asking for A100 owners o help him derive the algorithm used by the A100’s DRO system. Whether anything will come of this — or whether a DRO manipulation plugin is really necessary - I’m all for it.

One of the ways to determine the health of camera community is to watch for users making hacks, mods and tweaks to their photo gear. If there is a low amount of this sort of thing, the community isn’t thriving. If users are banding together to share information and help one another create modifications to their cameras and lenses, you can bet that is a growing community.

Sometimes camera makers frown at this sort of thing, but they really should appreciate how an active community can boost sales and brand awareness. Canon seems to be blessed with a number of active camera hackers, and it hasn’t seemed to hurt their bottom line. There was even a well publicized case where someone figured out how to hack the firmware on the original Digital Rebel to give it capabilities that were only available in higher priced models.

Camera hacking is healthy

That might sound like it could hurt the sales of higher priced cameras, but I expect that Canon got a tom of PR out of that exploit. At the same time, many users didn’t dare to apply the homebrew frimware hack, for fear they could end up with a unusable camera. So even people who didn’t own a digital Rebel (like me, for instance) heard about the hack, creating lots of brand awareness. But few people were willing to forgo buying the higher priced camera by taking a chance on messing up a perfectly good Rebel. It was all good for Canon.

So I welcome any homebrew experimenters willing to tinker with the Sony Alpha or Minolta Maxxum dSLRs. That’s how cameras get to be classics. The hackers start experimenting and share their findings on the web. Other users apply what they learned from the hackers and start improving their gear and their photography. Still others are intrigued and start their own experimenting and tweaking. The word gets out and it seems like everyone is modding their cameras. Or their lenses. Or their software. More equipment get sold, used gear retains value and the brand achieves cult status.

Like I said, nothing may come of this particular experiment. But it is a healthy indication. Sony would do well to encourage more of this sort of thing.

New Sony A700: a wake up call for photo media

Tuesday, September 11th, 2007

Features on new Sony dSLR place it in the top tier

Until we can actually get our hands on the new A700, we will have to turn to those lucky dogs who had a chance to actually use a pre-production A700. One of the more interesting preproduction reviews I’ve seen is Dan Richards’ Sony A700 field test at PopPhoto.com.

It seems that Richards was very, very impressed by the A700. Does this signal a major change in the photographic press?

While the Alpha A100 was showered with accolades when it was introduced, I always felt that the photo press simply didn’t know what to think about Sony’s A100.

The media was confused by the A100

The problem was that the A100 didn’t fit nicely into the categories established by the other manufacturers. The 10mp sensor broke a lot of ground in June 2006. Up until then, a 10mp sensor indicated a high-end dSLR. But the A100 had the price and feature set of a starter SLR. So it was either a high-end introductory model or a low-end advanced model. No one seemed to know which.

So the press had no yardstick to compare it to. The problem was intensified because the A100 was Sony’s only dSLR. So when the magazines ran those (usually useless) articles on “Which SLR system is right for you”, the Sony Alpha didn’t fit in very well.

All the other manufacturers had several different cameras that the media could compare against one another in a “shoot out” format. Sony only had a single camera and a handful of lenses, making it appear to be a limited “system” at best. Of course this mind set failed to take into account the millions of Minolta A-mount lenses available in the used market. The media generally doesn’t talk about used stuff when reviewing camera systems. So the photo press tended to ignore the Alpha, since they really couldn’t figure out how to categorize it.

Sony only compounded the problem by keeping their future Alpha plans secret and only doing limited marketing for the A100. It seemed both the press and Sony were intent on ignoring the Alpha line.

Alpha A700 set to impress the media

I believe the A700 might signal the end of that way of thinking. Unlike the A100, which had one foot in the low-end starter SLR camp and the other foot in the advanced dSLR corral, the A700 appears to be a true advanced enthusiast camera.

Until now, the press has divided the SLR market into two categories. There’s the Nikon/Canon group and then there’s everyone else. The Alpha was included in the second group by default.

The first group receives the lion’s share of coverage. Of course the smaller, secondary group does receive some recognition, but it usually pales when compared with the big two.

That was then. this is now.

In one swift (OK, not so swift) move, Sony has solidly moved into the Canon/Nikon class. It might not happen overnight, but the press can’t ignore the A700, it is too good of a camera. If the announced specs and picture quality live up to the press releases, the A700 is as good or better than anything in it’s price class.

If you read Richards’ article, he has nothing bad to say about the A700. He stresses that the improved auto-focus is excellent, shown by a Sony marketing stunt involving an attacking bi-plane.

For years I covered the auto industry “long lead press previews.” The auto manufactures would gather the press to show off their latest models. They were expert at arranging tests and situations that would paint their vehicles in the best possible light. They did their very best to let the press drive new vehicles in conditions that the car or truck excelled in.

Sony struts A700 Auto Focus for media’s benefit

If Sony was so so confident in the improved AF that they hired a bi-plane to buzz the demo A700 equipped photographic press, the AF on the A700 must be very good. Otherwise Sony would have arranged some other type of demo and avoided situations involving fast action.

Richards’ also calls the A700 controls excellent. This is in contradiction to the many users who bemoan the lack of extensive switches and dials available to set-up the Alpha 700. I too, am concerned that the A700 relies too much on menus instead of dials, but I haven’t used the camera. Richards has and he labels the controls and handling as excellent.

In his review, Richards says that his sunset shots taken at ISO 2000 appeared clean and sharp, although he doesn’t say whether he inspected the images on a computer monitor, printed them out or just looked at them on the A700’s 3″ LCD. Sony apparently didn’t allow images taken with the pre-release cameras to be taken home by the media, so we will have to wait to see high ISO images from production A700 cameras. Still, all indications are that Sony has taken great pains to reduce high ISO noise in the A700.

…by photographers for photographers…

At the end of his review, Richards says “…the A700 is a camera designed by photographers for photographers…” Wow. Those are the sort of comments the press used to make about Minolta SLRs. It’s not the typical comment we heard about the A100.

If the A700 is that good, I think we may see that the Sony Alpha series will shortly join Canon and Nikon as a top tier camera in the eyes of the photo press.

And then there were three….

Alpha A700 camera: the advanced amateur dSLR is announced

Finally! The news Alpha photographers hve been waiting for. Sony has announced their new Advanced Amateur dSLR, henceforth known as the A700, I like the name — it conjures up great Minoltas of the past, such as the X700, the Maxxum 7000 and the Maxxum 7D.

But the new model is a wide departure from those older SLR cameras. The feature set is very impressive, and if the picture quality lives up to Sony’s claims, Minolta A-mount shooters will be very happy indeed.

The A700 addresses almost all of the concerns I listed in my last post about Alpha A100 improvements. In addition to the vertical grip and PC sync we already knew was coming, the 12.2MP A700 feature set includes:

  • Optical glass pentaprism with interchangeable focusing screens
  • New 11 point enhanced auto focus system, claimed to be much faster than the A100.
  • Individual compartments for both Compact Flash and Memory Stick memory cards
  • Remote capture application offering tethered shooting via USB (yes!)
  • Continuous 5 frames per second, limited only by memory card size in JEPG, a healthy 18 frames can be captured in one burst when shooting RAW.
  • Sony claims the new dSLR is dust and moisture resistant. Is that the same as weather sealing?
  • New Dynamic Range Optimizer (DRO) function that sounds similar to built-in HDR (High Dynamic Range).
  • Ultra sharp 3″ LCD screen
  • The press release stresses in great detail that the A700 has been optimized to significantly reduce noise.
  • The initial Sony press release doesn’t mention ISO, but Engadget and several other sites claim the camera will offer 3200 ISO with some sort of extender mode to get the ISO to 6400

The new vertical grip will carry two InfoLithium(R) batteries and can automatically switch between cells when one battery is exhausted.

Body only price will be “about” $1,400. US. The A700K kit with a 18-70mm lens will set us back around 1,500, while the A700P kit will offer a 16-105 lens will go for $1,900. Sony is taking orders now. The body and A700k packages should be shipping in October, while the A700P will be on dealer’s shelves in November.

What’s missing? Live view. As I have said before, I’m not a fan of Live View so that isn’t a big disappointment for me.

That’s just the high-level overview. I’ll have more information and analysis after the dust clears and I can delve deeper into the A700’s features. in the meantime, A-mount shooters can take a deep breath and relax. If the press release is accurate, the A700 won’t be taking a back seat to anything else in it’s class. For the first time in a long, long while, we have a camera that boasts great features at an affordable price. Move over Nikon and Canon. There’s a new shooter in town!


Who is that guy?

Hi. I'm Tom Bonner and I've been shooting with Minolta SLRs for over three decades.

Alphatracks is my attempt to follow Sony's maneuvers in the dSLR market, and at the same time provide a resource for Minolta film and digital SLR users. A-mount shooters have to watch each other's backs, because there aren't as many of us. At least not for now....
