Lens Overview — Leica 90mm f/2 ASPH.

The Leica APO-Summicron-M 90mm f/2 ASPH. is a full-frame prime telephoto lens built exclusively for the Leica M mount system, making it at home on both rangefinder and M-mount compatible mirrorless cameras. With a fixed focal length of 90mm and a maximum aperture of f/2, this lens sits firmly in the short telephoto category, well-suited for portraiture, street photography at a distance, and detail-oriented work where subject separation matters. Focus is entirely manual, reflecting the deliberate, methodical shooting style that defines the rangefinder experience.

The lens accepts 55mm filters, which is a relatively compact thread size for a lens of this aperture class, pointing to an efficient optical package. Weighing in at 500g, it strikes a balance between substantiality and portability — noticeable on camera but not burdensome during extended use. There is no image stabilization, so steady technique or adequate shutter speed management is required.

The full-frame coverage means no crop factor concerns when paired with any Leica M-mount full-frame body, and the prime design ensures a focused optical formula dedicated entirely to the 90mm perspective. For photographers who value deliberate, manual shooting with a high-quality Leica M mount lens, this 90mm f/2 prime offers a compelling option in the telephoto prime segment.

Key Features — Leica 90mm f/2 ASPH.

APO-Summicron Optical Formula: Apochromatic correction minimizes chromatic aberration across all wavelengths, producing exceptionally sharp images with high color fidelity.

Aspherical Lens Element: The ASPH. designation indicates at least one aspherical element, reducing spherical aberration and improving edge-to-edge sharpness at wide apertures.

90mm f/2 Prime: A fast, fixed 90mm focal length optimized for portraiture and detail work, delivering strong subject separation at f/2.

Leica M Mount: Designed exclusively for the Leica M bayonet mount, ensuring precise mechanical and optical integration with M-system rangefinder and compatible mirrorless bodies.

Full-Frame Coverage: Covers a full 35mm full-frame image circle with no vignetting on any Leica M full-frame body.

Manual Focus Design: Fully manual focus operation suits the deliberate, rangefinder-coupled shooting workflow that defines the Leica M system.

Description — Leica 90mm f/2 ASPH.

The Leica APO-Summicron-M 90mm f/2 ASPH. is a prime telephoto lens designed exclusively for the Leica M mount, covering a full-frame image circle. With a fixed focal length of 90mm and a maximum aperture of f/2, it occupies the short telephoto range and is well-positioned for disciplines that benefit from a tighter field of view and moderate subject compression. Focus is entirely manual, consistent with the rangefinder tradition of precise, deliberate focusing.

The lens weighs 500g and features a 55mm filter thread, reflecting a compact and efficient physical design for its aperture class. There is no image stabilization, placing the onus on shooting technique or in-body stabilization where available. Compatible with Leica M mount mirrorless and rangefinder systems, this lens is a purpose-built prime for photographers invested in the M-mount ecosystem who require a capable, fast telephoto prime with full-frame coverage.

Pros — Leica 90mm f/2 ASPH.
