I really wanted this to work but sadly it did not. First, it is noisy as heck and second it hunts under indoor lighting conditions. Third, while they claim it can be updated I never could get it to update and I tried. Years ago, I even asked the company to update it for me and I would pay for the shipping, no answer. Now the adapter sits on the shelf collecting dust instead of pictures as a reminder don't be fooled again. Better to buy a quality manual focusing adapter for each lens or just give up on adapting Contax G lenses and or buy native Sony glass.
