Can be used with α7iii. infinity ok with supertakumer55mmf1.8 It's a pity that the grease comes out when you turn the helicoid. It took 19 days to Japan
The bayonet is way too tight for an A7III: once you connect adapter and camera you can only turn it a bit. I don't want to apply excessive force to try to turn until it locks. Maybe you can risk using this unlocked adapter with a small, light lens but I wouldn't t trust it with a heavy lens (a typical use case for a macro focusing helicoid). Disappointing! Maybe, it will work on the partly plastic original mount on the first generation A7 camera's ...
