Olympus OM to C-Mount Adapter

This adapter connects Olympus OM lenses to C-mount camera bodies, letting photographers reuse legacy glass on modern astronomy or industrial sensors. It is built for users who want manual aperture and focus control without electronic communication.

Mechanical Integration in a Lens Stack

The unit sits between the lens and camera, requiring no additional power or firmware, and it preserves the optical path so infinity focus remains accurate. It frees up the ability to mount 35 mm format Olympus OM optics onto smaller C-mount formats such as the Nano1 astronomy camera.

Sustained Use Behaviour

Precision machining keeps the lens-to-sensor distance stable during long exposures, preventing focus drift that can ruin astrophotography sessions. Durable construction resists wear from repeated mounting cycles in field or studio workflows.

Questions about this item

Will the adapter hold infinity focus with a 35 mm Olympus OM lens on a C-mount camera?

The adapter is engineered with precise depth so Olympus OM lenses reach accurate focus at infinity on C-mount bodies.

Does the all-metal construction heat up or affect sensor temperature during long astrophotography sessions?

The adapter is a passive mechanical spacer with no electronics, so it generates no heat and does not influence sensor temperature.

Must the Olympus OM lens have a manual aperture ring for this adapter to work?

Yes, the adapter provides no electronic contacts, so aperture and focus are controlled entirely by the lens's own rings.
