Lens Overview — Leica 135mm f/3.4
Key Features — Leica 135mm f/3.4
APO Apochromatic Design: Apochromatic correction brings all wavelengths of light to the same focal plane, virtually eliminating chromatic aberration for sharper, more color-accurate images across the frame.
135mm Full-Frame Prime: Fixed 135mm focal length delivers strong subject compression and background separation well-suited to portraiture, street, and distant subjects on full-frame M bodies.
Leica M Bayonet Mount: Natively compatible with the full range of Leica M-system rangefinder and mirrorless cameras, including the M10, M11, and their predecessors.
f/3.4 Maximum Aperture: A practical working aperture for a telephoto of this class, allowing meaningful background separation while keeping the lens compact and optically well-corrected.
Manual Focus Only: Fully manual focus operation is consistent with the Leica M rangefinder shooting philosophy, requiring coupling through the camera's rangefinder mechanism.
Compact 49mm Filter Thread: A relatively small 49mm filter diameter keeps filter costs low and adds minimal bulk for a lens of this focal length.

Description — Leica 135mm f/3.4
The Leica APO-Telyt-M 135mm f/3.4 is a manual-focus telephoto prime built around the Leica M lens mount, intended for use with Leica M mirrorless camera systems. With a fixed 135mm focal length, it sits squarely in telephoto range, offering the subject isolation and compression characteristics associated with longer primes. The lens covers a full-frame image circle, making it a natural fit for full-frame Leica M bodies.
Its maximum aperture of f/3.4 provides a workable exposure latitude across a range of lighting conditions. Weighing in at 450g, it remains a relatively portable option for a telephoto prime of this reach. The 49mm filter thread is compact and cost-effective for accessory use.
It is worth noting that this lens has no image stabilization and is manual focus only, so it rewards deliberate, considered shooting style — very much in keeping with the rangefinder tradition. The Leica M Hot Shoe is also noted in the mount specifications for accessory compatibility.
Pros — Leica 135mm f/3.4
- ✓Fixed 135mm focal length in a full-frame telephoto prime format
- ✓Compact 49mm filter thread keeps filter costs and accessory weight down
- ✓Lightweight at 450g for a telephoto prime of this focal length
Cons — Leica 135mm f/3.4
- ✗Manual focus only — no autofocus option for faster-moving subjects
- ✗Maximum aperture of f/3.4 is relatively modest for low-light or shallow depth-of-field work at this focal length
- ✗No image stabilization, requiring careful technique at 135mm for sharp handheld shots
