Leica 28-35-50mm f/4 Tri-Elmar-M ASPH. M-Mount Lens, Black, 6-Bit Review

The Leica 28-35-50mm f/4 Tri-Elmar-M ASPH is a compact three-focal-length lens designed for Leica M-mount rangefinder cameras. It covers the classic documentary and street photography range, allowing shooters to switch between 28mm, 35mm, and 50mm by rotating a lever on the barrel. This eliminates the need to carry multiple primes while maintaining the slim profile that M shooters prize. The constant f/4 aperture is modest by rangefinder standards, but the aspherical design and 6-bit coding promise strong optical performance and seamless integration with digital M bodies. At just under $2,500, the Tri-Elmar occupies the sweet spot for Leica glass, less than premium Summilux primes but still a serious investment. It appeals most to travelers and documentary photographers who want flexibility without bulk, though the mechanical focal length selector adds a step that purists may find less elegant than simply swapping lenses.
