Is the sigma 35mm f 1 4 dg ii art sharp wide open?

I don't have any test results or sharpness measurements for the Sigma 35mm f/1.4 DG II Art, so I can't tell you how it performs wide open. What I can confirm is that it's a full-frame prime for Sony E and L-Mount, with autofocus but no stabilisation. On APS-C it frames like about 52mm. You can see the full camera list on its lens page.

For how f/1.4 behaves in practice, the Lenses guide explains what a wide aperture changes, and the Portraits guide covers how thin depth of field can get at f/1.4. For sharpness itself, look for hands-on reviews from people who've shot with it.
