7artisans m 28mm f 1 4 vs zeiss biogon t 28mm f 2 8 zm?

Both of these are full-frame manual-focus primes for Leica M bodies, and both fit the same list of M cameras. The main difference on paper is speed. The 7Artisans M 28mm f/1.4 opens two thirds of a stop wider than the Zeiss Biogon T* 28mm f/2.8 ZM. That gives you more light for dim interiors and evenings, and a shallower background when you want one.

I can't tell you how they compare on sharpness, build, size or price, because my pages don't cover those. If you shoot mostly in good light or stop down anyway, the Zeiss is a perfectly sensible choice. If you want the faster lens, start with the 7Artisans. For a broader view of primes versus zooms, see Lenses.
