Overview

The Canon 25mm f/3.5 LTM is a tiny, lightweight rangefinder lens (5.3 oz) with a deeply recessed front element, eliminating the need for a hood. It uses a Zeiss Topogon formula, offering corner-to-corner sharpness on APS-C. However, its single coating makes it prone to flare. Built from 1956–1975 in Leica screw mount, it suits vintage rangefinder enthusiasts and those seeking a compact, sharp ultra-wide for film or digital, provided flare is managed.
