Nice well machined, well coated adapter. Looks good too. Unlike a cheaper version I tried the release catch is well designed and doesn't let light in, so the extra money (this is thrice the price) is worth it, and I didn't have to wait several weeks to get it. Using a 1970s Summicron-R 50mm lens it takes suberb photos on my Fuji XT-10. Note that this transmits no lens information to the camera, neither mechanically (from a Leitz lens cam) nor electronically if your lens has contacts. So it has to be used with a camera which has automatic shutter control or be used manually.
