M42 to OM Lens Adapter Ring

This aluminium adapter ring lets photographers attach M42 screw-mount lenses to Olympus OM and Micro Four Thirds camera bodies. It weighs 27 grams and is constructed from anodised aluminium alloy for durability. The ring provides a purely mechanical connection with no electrical contacts, so aperture and focus must be controlled manually on the lens itself.

Replaces Direct M42 Mounting

The adapter removes the need for a dedicated M42 camera body when using legacy lenses on 4/3 or Micro Four Thirds systems. It is a worthwhile addition when a photographer already owns M42 optics and wants to use them on cameras such as the Olympus E520, E620 or Panasonic L1. The jump makes sense for manual-focus enthusiasts who accept losing autofocus and automatic aperture control.

Suits Manual-Focus Shooters

This ring suits photographers who enjoy adapting vintage M42 glass to modern 4/3 and Micro Four Thirds bodies and are comfortable setting exposure and focus by hand. It will not suit users who require autofocus, electronic aperture control or EXIF data transfer, as the adapter has no electrical interface. Buyers needing automatic lens communication should look at a different solution.

Questions about this item

Will the 27 g adapter ring fit the Four Thirds bayonet on my Olympus E-520?

Yes, the ring is configured for Olympus E520, E620, Panasonic L1 and other 4/3 bayonet cameras.

How do I attach the M42-OM adapter without damaging the lens or camera mount?

Align the red dots, insert the adapter into the camera bayonet first, then twist the M42 lens onto the adapter until it locks; do not force the threads.

Does the aluminium alloy ring need lubrication or replacement after extended astrophotography sessions?

No lubrication is required; the anodised aluminium construction is durable for long time use and the package includes only the single adapter ring.
