… er, SL-TTL-EVF*. Here’s the details:

Note that the Minolta DiMage 7, 7i, 7ug, 7hi series had matching lens-to-sensor coverage – full frame. Okay, not 35 mm frame, but full-frame matching lens and sensor nonetheless.

Then, later, the exact same lens plus capture sensor size appeared in the Minolta DiMage A1 with sensor-based anti-shake.

Minolta used a severe (+4%?) corner fall-off / vignette compensation filter, but I believe they use it on the entire series – see

http://www.dalibor.cz/minolta/plugin_user_guide.htm

for a sample quote from Dalibor Jelinik:

“…Normally the highest number of a pixel captured is 3,965. But the camera occasionally captures a picture whose maximum value is higher then 3,965, up to 4,095. This is to allow for “vignetting compensation” that occurs when shooting with an aperture of f/2.8. Yes, the camera vignettes at this aperture. The vignetting is hard to see in the corners because the camera multiplies based on a mask to brighten the corner pixels. After this compensation there might be some pixels with values greater than 3,965 (those are the pixels in the corners that were close to maximum before multiplication based on the mask)…”

So, I’m happy with the thought of a Sony Alpha full-35-mm frame SSS anti-shake system, even selectable such that I know that

ON = AS+corner-compensation-filter,

OFF = no filter, for purists.

* SL-TTL-EVF = single lens through the lens electronic viewfinder, an SLR without the R.

I read Bert’s comments and it made sense but I have one question about sensor size that I have never seen addressed. Why can’t we have a sensor slightly larger then full frame so that no matter where the circle falls it is on the sensor and the camera can auto crop the area not used? Just a thought from someone that has no idea what happens between when I press the shutter release and when I pull my CF card out! LOL]]> Tom,

I am not an engineer of any type! I don’t know how the SSS stuff works beyond what I have read here and other sites.
