Overview

The Minolta M-Rokkor 40mm f/2.0 is a compact, well-built M-mount lens optically identical to the Leica Summicron-C 40mm f/2, with improved coatings on later versions. It delivers modern sharpness with vintage character, including some flare and vignetting. Weaknesses include low-resistance focus rings and slack helicoids, and it brings up 50mm framelines on most Leica M cameras. It suits photographers seeking an affordable, tiny 40mm lens for rangefinder or mirrorless use, offering excellent value.
