What is the zeiss otus ml 85mm f 1 4 good for?

The Zeiss Otus ML 85mm f/1.4 is a full-frame portrait lens. It's the kind of lens I'd reach for when I want flattering perspective, soft backgrounds, and room between me and my subject. On portraits, I'd call the 85mm the classic full-frame portrait focal length.

Its f/1.4 aperture gives very thin depth of field, so focus on the eyes. For two people at different distances, stop down to around f/2.8. It's manual focus only and not stabilised, so it suits deliberate, unhurried shooting. It fits Sony E, Canon RF and Nikon Z mounts.
