90mm · f/2.8
The Konica M-Hexanon 90mm f/2.8 is a rangefinder lens made for the Konica Hexar RF, with a mount similar but not identical to Leica M, causing focus issues on Leica bodies. Optically, it has no visible distortion and low falloff, but is inferior to Leica equivalents. Build quality is crude with sharp edges. It suits users who can adapt it to mirrorless cameras or accept its limitations on Leica bodies.
