Lens Overview — Leica 75mm f/2 ASPH
Key Features — Leica 75mm f/2 ASPH
APO-Summicron Optical Formula: Apochromatic correction minimizes chromatic aberration across the full aperture range, producing sharp, color-accurate images even at f/2.
Aspherical Lens Element: The ASPH designation indicates at least one aspherical element, reducing spherical aberration and contributing to exceptional edge-to-edge sharpness.
75mm Full-Frame Prime: A focal length that sits between classic portrait and short telephoto ranges, well suited to head-and-shoulders portraits and subject isolation.
f/2 Maximum Aperture: Provides strong light-gathering capability for a telephoto prime, enabling handheld shooting in lower light and meaningful background separation.
Leica M Mount: Designed exclusively for the Leica M system, ensuring native compatibility with full-frame M-body rangefinder cameras without adapters.
Manual Focus Only: Optimized for rangefinder-coupled manual focusing, aligning with the deliberate, tactile shooting style of the Leica M system.

Description — Leica 75mm f/2 ASPH
The Leica APO-Summicron 75mm f/2 ASPH is a prime telephoto lens built exclusively for the Leica M mount, targeting photographers working with full-frame mirrorless rangefinder cameras. At f/2, it delivers a wide maximum aperture for its focal length class, offering flexibility when light levels drop or when subject separation is the priority. Sitting in the telephoto category at a fixed 75mm focal length, it is a natural choice for portrait-distance work and controlled compositions.
Focusing is entirely manual, with no autofocus system — a deliberate design choice that suits the rangefinder workflow. There is no image stabilization, so handling technique matters. The lens accepts 49mm filters and weighs 430g, keeping it compact relative to its aperture and focal length.
For photographers committed to the Leica M system, this lens represents a precise, optically dedicated option for telephoto prime shooting.
