Lens Adapter Pixco: Canon EOS (EF/EF-S) to Olympus OM mount SB1904

The Pixco Lens Adapter for Canon EOS (EF/EF-S) to Olympus OM mount SB1904 is a mechanical adapter designed to allow Canon EF and EF‑S lenses to be mounted on cameras with an Olympus OM mount. This adapter provides a physical connection and optical alignment between lens and camera body without electronic contacts, preserving manual control of aperture and focus. It is intended for photographers who want to use legacy Canon lenses on OM‑mount camera bodies for still photography and who accept manual operation of exposure and focus functions.

Advantages

The adapter offers reliable mechanical coupling and precise flange distance alignment to maintain correct focusing across the supported lens range. Its construction ensures secure locking of Canon EF/EF‑S lenses to Olympus OM bodies, while the absence of electronic communication avoids compatibility issues with unsupported electronic protocols. Lightweight and compact, the adapter minimally affects handling and balance when using heavier vintage lenses.

Suitable for

• Photographers using Canon EF or EF‑S lenses on Olympus OM mount cameras
• Owners of legacy or third‑party Canon lenses who need a mechanical mounting solution
• Still photography where manual focus and aperture control are acceptable
• Macro, portrait, and landscape shooting with adapted prime and zoom lenses

Key specifications

• Mount conversion: Canon EOS (EF/EF‑S) lens to Olympus OM camera mount
• Operation type: Mechanical coupling only, no electronic contacts
• Controls preserved: Manual aperture (where lens supports) and manual focus
• Material: Metal alloy construction for durability and stable attachment
• Finish: Corrosion‑resistant coating to protect mating surfaces
• Locking mechanism: Secure bayonet lock compatible with Canon EF/EF‑S lens mount
• Weight and size: Compact, lightweight design to reduce added bulk on camera

How to use

Mount the adapter onto the Olympus OM camera body by aligning the adapter's OM mount index with the camera's mount mark and rotating until it locks into place. Attach a Canon EF or EF‑S lens to the adapter by aligning the lens's bayonet marks and turning until the lens clicks securely. Set the lens aperture and focus manually on the lens barrel; set the camera to a mode that allows manual exposure control if necessary. Verify infinity focus and adjust focus manually as required; some lenses may require micro‑adjustment for precise focus at certain focal lengths.

Usage recommendations

Use the adapter on stable support such as a tripod when working with heavy lenses to reduce stress on the camera mount. Check lens compatibility before use, especially with EF‑S lenses on certain OM cameras, and avoid autofocus-dependent workflows since electronic AF and image stabilization will not operate through this mechanical adapter.
