I am buying a Contax G 45mm lens and the seller has offered me his TechArt TA-GE1B adapter for $100. Has anyone used it on an A6000? Worth it? I know of, but very little about, the TechArt adapters, and most of what I found related to use on A7 series bodies. From what I have been able to gather, this is v2 of the adapter. I think that means non-upgradeable firmware, and contrast detection AF, correct? I gather you can override the AF and use it with manual focus. Hopefully it would work as well as any other manual adapter that way, so if I find the AF unreliable it would still be a decent MF adapter. I currently have a G90 on a Kiwi manual adapter and have not had much difficulty. AF would be a nice extra if it works well, but I am stretching my limited gear budget a bit to get the 45mm so I do not want to throw $100 into this if it does not work all that well.
