Voigtl nder color skopar 21mm f 4 p vs leica super elmar m 21mm f 3 4 asph?

Both are 21mm manual-focus primes for full frame, both on the Leica M mount, and neither is stabilised. On paper, the main difference is aperture. The Leica Super-Elmar-M 21mm f/3.4 ASPH gives you a little more light than the Voigtländer Color-Skopar 21mm f/4 P, which helps indoors and at dusk. Both are small, so you'll frame on the back screen or through an external finder, live view or EVF.

If that extra light matters to you, I'd go with the Leica. If you mostly shoot in good light, the f/4 Voigtländer covers the same 21mm view. Both fit the same bodies, from the Leica M9 to the Leica M11. The Leica M mount page has more on what fits.
