Best camera for the zeiss planar t 50mm f 1 4?
The Zeiss Planar T* 50mm f/1.4 is a manual-focus lens for Canon EF or Nikon F, and it frames as a true 50mm on full frame, so I'd start there. My everyday pick is the Canon EOS 6D Mark II, a sensible full frame body that works well with a manual lens. If you'd rather go Nikon, the Nikon D750 does the same job. If you want the most resolution and don't mind the extra bulk, the Nikon D850 is the one I'd look at.
Because you'll be focusing by hand, pick a body that feels comfortable and easy to see through, and hold it in a shop if you can. If you're still deciding on a body, your first camera walks through the choice.
