Recently purchased the Mount and have been using vintage lenses on it with our FX3. Love every bit of it.
Works great on my Pentax Takumar 35mm f/3.5, and 200mm f/4. Only problem I have is my Super Multi Coated Takumar 50mm f/1.4. The inner back ring of the adapter is slightly too narrow and it grinds into and bends the aperture control switch on the rear of the lens. This will only affect the Super Multi Coated or SMC lenses, but the standard Super Takumar's will be fine. Might be due to imprecision during manufacturing.
High quality, well designed, even the packaging is aesthetic.
Couldn't recommend more!
Love that I can use classic lenses on my Sony A7ii. Adds another layer to my photography.
