Olympus OM to Leica M adapter compatibility
Mounting a Olympus OM lens on a Leica M body — the feasibility verdict, AF / IS / aperture-control / infinity-focus outcome, image-circle relationship, official and reputable third-party adapter SKUs, and the caveats worth knowing before you buy.

Mount specs
Lens side
Olympus OM

Flange-distance gap the adapter fills: 18.20 mm (46 mm − 27.8 mm). That gap is what a mechanical adapter has to fill to hold the lens at its design distance from the sensor.
Adapter examples
- generic mechanical adapter ring (multiple vendors)
Caveats
- Mechanical adapter only — no electronic communication between Olympus OM lens and Leica M body.
Common questions
- Will Olympus OM lenses autofocus on a Leica M body through an adapter?
- Autofocus is not applicable to this pairing — the Olympus OM mount predates electronic AF, or the bodies in this family do not implement AF for adapted lenses.
- Does in-lens image stabilization (IS / VR / OS) still work through a Olympus OM → Leica M adapter?
- Stabilisation is not applicable — Olympus OM lenses in this family do not ship with in-lens stabilisation, or the adapter pair predates the IS protocol entirely.
- What's the most-recommended Olympus OM → Leica M adapter?
- No SKU in our curated catalogue covers Olympus OM → Leica M yet. Adapter examples photographers commonly use include the generic mechanical adapter ring (multiple vendors). Pair compatibility is mostly mechanical, so any well-built adapter at the correct flange distance should work — pick on build quality and tripod-foot integration.
