With the growing popularity of using our Sony's with legacy glass, there are now so many adapters on the market. Not all are created equal in all likelihood. Perhaps we could start a review thread for adapters and their sources. I know it would have helped me on my quest for adapters to use with my a6000. Most are simply a basic extension tube, or stubby ring. It would seem pretty staightforward to design a proper adapter. I received one for Nikon F/Ai mount to NEX E mount that seems to not allow me to focus to infinity. Annoying to say the least. A situation I bet must have been shared by others. And a thread of reviews may help, and possibly improve the products out there. Your thoughts, and experiences? TIA!
