Commlite lens adapter for Olympus/Panasonic Micro Four Thirds (M4/3) to Olympus Four Thirds - AF support

The Commlite lens adapter allows mounting Olympus/Panasonic Micro Four Thirds (M4/3) lenses onto Olympus Four Thirds camera bodies. This mechanical adapter preserves the physical connection between lens and camera and is designed to provide autofocus-compatible operation when paired with supported lenses and camera bodies. It enables photographers to expand their lens options by using M4/3 glass on 4/3 mounts for alternative focal lengths and creative combinations.

Advantages

The adapter offers a straightforward mechanical interface that maintains aperture control where the lens supports it, while also providing electronic contacts intended to enable autofocus communication on compatible combinations. Its compact design minimizes additional extension to preserve handling and balance when mounting smaller M4/3 lenses on larger Four Thirds bodies. The construction focuses on reliable alignment and stable mounting to reduce play and ensure consistent optical performance.

Suitable for

• Photographers who want to use Micro Four Thirds lenses on Olympus Four Thirds cameras
• Those seeking extended focal length or specialized optics not available in native 4/3 mount
• Users experimenting with cross-mounting for creative or technical purposes

Key specifications

• Mount conversion: Micro Four Thirds lens to Four Thirds camera body
• Mechanical adapter with electronic contact support for autofocus where compatible
• Maintains physical aperture control where supported by lens
• Compact, lightweight metal construction for stable mounting
• Designed to minimize flange focal distance change to preserve focus range

How to use

Align the adapter’s index marks with the lens bayonet, attach the Micro Four Thirds lens to the adapter, and rotate until it locks into place. Then align the adapter with the Four Thirds camera mount and secure it by rotating until the adapter clicks. When mounting, check that electronic contacts are clean and properly seated to allow any available autofocus or aperture communication. Follow the camera and lens manufacturer guidelines for mounting and release to avoid damage to the bayonets.

Usage recommendations

Test autofocus performance and aperture control with your specific camera and lens combination before critical shooting; supported functionality can vary by model. Use manual focus and exposure modes if the camera does not recognize the lens or if AF performance is limited. Store the adapter and connected lenses with caps when not in use to protect mounts and contacts.
