Leica 90mm f/2 Summicron-M M-Mount Lens, Canada, Black, 6-Bit Review

The Leica 90mm f/2 Summicron-M is a classic medium telephoto prime for M-mount rangefinder cameras, positioned squarely in Leica's legendary Summicron lineup. This particular example is a used, Canadian-made unit in excellent condition with caps and 6-bit coding for digital M bodies. At f/2, it offers a useful combination of speed and compactness for portraiture, street work, and detail shots where 90mm framing suits the photographer's style.

Leica's Summicron lenses are known for their mechanical precision, rendering quality, and durability. The 90mm focal length on a full-frame rangefinder demands careful focus technique but rewards users with smooth bokeh and sharpness across the frame. The 6-bit coding ensures compatibility with modern digital M cameras for optimized image processing. At this price point for a used example, it sits well below new Leica glass but still reflects the premium associated with M-mount optics.
