Voigtl nder ultron vintage line 28mm f 2 aspherical vs zeiss biogon t 28mm f 2 8 zm?

Both lenses are 28mm manual-focus primes for full-frame Leica M bodies, and both fit the same list of cameras, from the Leica M9 through the Leica M11. The main difference is aperture. The Voigtländer Ultron 28mm f/2 lets in twice the light of the Zeiss Biogon T* 28mm f/2.8, so it's the one I'd pick for dim interiors, evening street work, or a little more background blur.

If you shoot mostly in daylight and want the lens that's most likely to suit your needs, the f/2.8 Biogon is a sensible choice. I can't tell you which one is cheaper or smaller from what I have, so check current prices before you decide.
