Best camera for the zeiss otus ml 50mm f 1 4?
The Zeiss Otus ML 50mm f/1.4 is a full frame lens, so I'd pair it with a full frame body. It's manual focus only, so you'll be focusing by hand, and a body you already enjoy using will make that easier.
For an everyday pick, I'd go with the Sony a7 IV on Sony E. If you're on Canon RF, the Canon EOS R6 Mark II is a solid choice. For Nikon Z, the Nikon Z8 is the one I'd reach for.
You can also put it on an APS-C body like the Sony a6700. It then frames like about 75mm, which suits portraits well. Full frame is still the better match for this lens.
