Is the zeiss otus ml 85mm f 1 4 sharp wide open?

The site doesn't have sharpness tests for the Zeiss Otus ML 85mm f/1.4, so I can't tell you how it performs wide open. What I can tell you is that it's a full frame, manual-focus prime, and it opens to f/1.4. Its catalogue page lists the cameras it fits, along with its mounts and how it frames on APS-C.

If you're deciding on wide-open use, the aperture explainer covers what f/1.4 does for light and background blur. At f/1.4 the depth of field can be thinner than a face, so check your focus carefully. The portraits guide has more on that.
