Is the voigtl nder apo ultron 90mm f 2 sharp wide open?

I don't have sharpness test results for this lens, so I can't tell you how it performs at f/2 from this site. What I can tell you is that it's a 90mm f/2 prime for full frame, with manual focus only and a Leica M mount. Its lens page lists the Leica M bodies it fits, from the M9 through the M11 family.

Wide open, f/2 gives shallow depth of field, so focus has to be precise. The aperture guide explains what that means for light and blur, and the portrait notes cover how focal length and distance change the background. For a sharpness verdict, look for independent lab or user tests of this lens before you buy.
