Hi Shirley,

Thanks for your question. MC (Rokkor) lens to Sony A-Mount adapters used to be rare and hard to come by, but today they are quite plentiful.

You will find two different kinds of Rokkor to Sony adapters. Some are marketed as “no-glass” or macro adapters, while others contain a lens or or “optical glass.”

Most users will need the adapter with optical glass. The no-glass adapters will allow you to shoot close-ups and macro shots, but the adapters without glass cannot focus to infinity. So if you want to shoot images beyond close-ups, avoid the no-glass adapters and purchase a more-expensive adapter with optical glass.

You can start on ebay, if you are comfortable buying from China or Hong Kong. I have had no trouble with these foreign dealers, but sometimes you have to wait to receive your items.

Try these eBay listings for dealers selling optical glass adapters:

Closer to home, B&H Photo sells the General Brand Lens Adapter for Sony Alpha/Maxxum Body to Minolta MD. http://www.bhphotovideo.com/c/product/97536-REG/General_Brand_Maxxum_Body_to_Minolta.html
The description does not say it has an optical glass lens, but judging from the price, I assume it does. If you order from B&H make sure it contains a glass lens.

You will also find numerous MC to MA adapters on Amazon. Just make sure you look for a MC/MD adapter designed to fit the Sony Alpha A-mount (Not E-mount, unless you are using a NEX model camera.) Again, get an adapter with optical glass so you can focus at infinity:

I hope that helps. Remember that on your A350 you will have to shoot in the manual mode if you use and adapter.

Regards, Tom
