Just published in my Guide to Leica is a aperture series in 1/2 stops from f/3.4 - f/16 for the new Leica 21mm f/3.4 Super-Elmar-M. The 21/3.4 Super-Elmar-M is a superlative performer. If only Leica offered twice the resolution in the M line, the 21/3.4 would deliver admirably.
Much more coming on the Leica 21mm f/3.4 Super-Elmar-M.
