Just got my Techart adapter 2 days ago. Downloaded version 4 of the firmware yesterday. I was prepared for a letdown from high expectations, but it didn't happen. I have only tried on two lenses so far--Leica 50mm Summicron and Zeiss ZM 85mm f/4--and I am more than pleased. I am shocked at this technological marvel. Shot at a lot of different apertures with both lenses yesterday, favoring wide open particularly when light wasn't great, and focus was very accurate. At least for focusing people, a much better hit rate than I would have had focusing manually.
To raise an old issue, not related to the Techart adapter but rather to adapting wide angle M out lenses on the Sony A7 series (i.e. the thick stack sensor issue), what 24mm, 28mm and 35mm M mount lenses have people mounted recently that have performed well?
Thanks!
