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

The site doesn't say how sharp this lens is wide open. What I can tell you is that focus is very thin at its widest setting, so getting the eye in focus takes care. The lens is heavy and manual focus only, and the page lists its maximum aperture as f/0.9.

If you shoot it wide open, expect a very shallow zone of sharpness. Aperture explained covers what the f-number does to light and blur, and Portraits shows how to keep a face sharp when the depth of field is this thin. The lens fits a long list of full-frame Leica M bodies, such as the Leica M10 and the Leica M11. For full details, see the Leica Noctilux-M 50mm f/0.95 ASPH page.
