I used a canon with a SLR (I adjusted it myself using a USB Dock, here you need to work a little, but the sharpness is accurate) Now I use it with a Sony 6400 mirrorless camera and no USB Dock is needed, of course. Everything is sharp, autofocus through the MC-11 adapter is fast and accurate. Glass is the best in its segment, although it costs several times more than in 2022, when I bought it. This is a very cool lens, the picture from it is cinematic, and my favorite focal length is 35 mm.
