Is the canon ef 85mm f 1 2l ii usm sharp wide open?

I don't have sharpness test results for the Canon EF 85mm f/1.2L II USM, so I can't tell you how crisp it is at f/1.2. What the page does tell you is that it's an 85mm prime at f/1.2 for full frame, and it fits a long list of Canon EF bodies, both full frame and APS-C. You can see the full specs on the lens page.

If you're deciding for portraits, the portraits guide covers how thin focus gets at f/1.4 and wider. It's worth knowing that at those apertures the depth of field can be thinner than a face, so you may end up stopping down a little for groups. For the basics of how the f-number affects light and blur, see the lenses guide.
