Received my adapters in the mail yesterday. I had troubles out of the gate trying to update the firmware on the TAP adapter. Finally figured it out this afternoon and put on lens to try it out. Talk about disappointed. It maybe hit 10% focused, but soft. What a waste of time and money. Went inside and did some more reading and read that the firmware on the camera might be out of date so I checked mine - version 1.20, the current version is 3.20. I downloaded the new firmware and stuck on a different lens. Well let me say that it now lives up to the hype I had read. I am very pleased with my purchase, breathes new life into some of my manual focus lenses. Will spend some time with them over the next few days and see how they perform now. Color me impressed so far.
