Lens mount adapter Pixco: Olympus Four Thirds (4/3) lens to Olympus OM camera bodies

Pixco mechanical lens mount adapter enables the use of Olympus Four Thirds (4/3) lenses on cameras with Olympus OM mount. This precision-machined metal adapter provides a secure physical connection between a 4/3 lens and an OM-mount body, preserving correct flange distance for accurate focus. There are no electronic contacts or communication between lens and camera, so aperture and focus are adjusted manually on the lens itself. The adapter is intended for photographers who wish to reuse legacy Four Thirds optics on OM-mount cameras for manual operation, vintage rendering, or creative control.

Advantages

The adapter is constructed from durable metal for reliable mechanical coupling and repeatable alignment. Its design maintains proper optical registration so that focusing performance is retained when used within the mechanical limits of the lens and camera combination. Without electronic interfaces, the adapter is simple to mount and requires no firmware or power, offering a straightforward solution for adapting 4/3 lenses to OM bodies. The compact, lightweight build minimizes added bulk while providing a solid mount for shooting.

Suitable for

• Photographers wanting to use legacy Olympus Four Thirds lenses on OM-mount camera bodies
• Manual-focus portrait, landscape, and creative photography
• Testing and comparing vintage optics on modern OM bodies
• Workshops, teaching, and hands-on lens technique practice

Key specifications

• Mount input: Olympus Four Thirds (4/3) lens side
• Mount output: Olympus OM camera body side
• Construction: metal alloy housing with precise mechanical tolerances
• Electronic communication: none — manual aperture and focus control only
• Compatibility: designed for physical adaptation of 4/3 lenses to OM mount without optical elements
• Finish: matte or anodized surface to reduce reflections

How to use

Align the index marks on the adapter and lens, then rotate the lens until it locks into the adapter mount. Attach the adapter with the mounted lens to the OM camera body by aligning the adapter’s mount mark with the camera’s mount mark and turning until it clicks into place. Set the camera to a manual or mechanical lens-compatible mode as required to permit manual exposure control and metering. Adjust focus and aperture directly on the lens; use viewfinder or live view for focusing assistance. To remove, press the camera’s lens release and rotate the adapter and lens assembly off the camera mount.

Usage recommendations

Confirm physical compatibility of lens and camera mounts before use. Because there are no electronic connections, features such as autofocus, EXIF aperture reporting, and electronic aperture control will not function. For accurate exposure and focus, rely on manual controls, focus peaking or magnified live view where available. Handle the adapter and vintage lenses carefully to avoid dust ingress and mechanical wear; store in a dry environment when not in use.
