Is the zeiss biogon t 35mm f 2 zm sharp wide open?

I don't have anything on how sharp this lens is at f/2. The Zeiss Biogon T\* 35mm f/2 ZM page covers the basics: it's a manual-focus prime for Leica M bodies, with a maximum aperture of f/2. It doesn't include test results, so I won't guess.

What I can tell you is how wide apertures behave. The lenses guide explains what f/2 means for light and background blur, and the portraits guide covers how shallow focus can get at wide settings. If sharpness wide open is the deciding factor for you, look for independent test reviews of this lens before you buy.
