What are the alternatives to the voigtl nder color skopar 35mm f 3 5 aspherical?

The site only has two other lenses to point you to, both Voigtländer Color-Skopar primes for full frame: the 28mm f/2.8 Aspherical and the Vintage Line 21mm f/3.5 Aspherical. Their mounts aren't listed on my pages, so I can't confirm they fit the Leica M bodies the 35mm works with. Check that before you buy.

If you want a different view from the 35mm, the 28mm is the closer step wider and the 21mm is much wider, good for interiors and big landscapes. For a standard view, the lenses guide suggests a 50mm, which is close to how we see. The 35mm's own page lists every body it fits, if you want to confirm your camera first.
