Is the ttartisan m 50mm f 0 95 asph sharp wide open?

The TTArtisan M 50mm f/0.95 ASPH page lists its specs, its f/0.9 maximum aperture and the Leica M bodies it fits, but it doesn't say how sharp it is wide open, so I won't guess. It is manual focus only, and on a Leica M it frames as a plain 50mm.

For what wide open means in practice, the Lenses guide explains how a fast aperture affects light and blur. The Portraits page covers how thin focus gets at f/1.4 and wider. My one pointer is the Leica Noctilux-M 50mm f/0.95 ASPH page, which calls focus very thin wide open. Expect a similar challenge here. Shoot a test frame at f/0.95 on your own body before you rely on it.
