Is the voigtl nder apo lanthar 28mm f 2 aspherical sharp wide open?

The site doesn't cover how sharp the Voigtländer APO-Lanthar 28mm f/2 Aspherical is wide open, so I can't give you a verdict on that. What I can tell you is that it's a manual-focus prime for full frame, with Sony E, Nikon Z and Leica M mounts. On APS-C it frames roughly like 42mm on full frame. You can see the full spec on its lens page.

If you want to know what f/2 gets you in light and background blur, the aperture section explains it. The same maker's 35mm f/2 is the other prime in this range if you prefer a slightly tighter view. Either way, I'd take a few test shots wide open before you commit.
