Is the voigtl nder nokton 75mm f 1 5 aspherical sharp wide open?

I haven't tested the Nokton 75mm f/1.5 Aspherical wide open, so I can't tell you how sharp it is at f/1.5. What the lens page does cover is its fit: it's a manual-focus prime for full frame, and it works on Sony E, Nikon Z, Canon RF and Leica M mounts.

Wide open at f/1.5 you get very thin depth of field, so focus has to land exactly on the eye. If you're planning portraits with it, read aperture and background blur first. For what the f-number does to light and blur in general, the lenses guide explains it well.
