This Lens Adapter from Rayqual allows you to mount an Olympus OM mount lens on your Canon EF-M-mount camera. The flange depth has been tested with a variety of camera bodies and lenses to deliver exacting performance and maintain infinity focus. It supports manual focusing in both Manual and Aperture Priority modes, and though autofocus is not supported, the adapter does allow you to use depth of field preview and stopped down metering if your camera and lens support it. Please note that when using In-Body Image Stabilization (IBIS), the focal length should be set in the camera. Made in Japan, the adapter has been designed and manufactured to maintain a parallel optical pathway while eliminating internal reflections.

Related Questions and Answers

Q: 1. Does this adapter impart any magnification factor to the Olympus lens? Some adapters do. The description doesn't say.

A: The Olympus OM series lenses were used on the Olympus OM series 35mm SLR cameras. A full frame sensor is modeled after a 35mm film frame, so using this adapter on the Nikon Z6/Z7 will keep the focal length of the OM lens the same. If using the OM lenses with the adapter on the Z50, which has the DX sensor, then a crop factor of 1.5X will be applied to the focal length.

Q: 2. Will putting a micro 4/3 lens on the z6 crop the image similar to putting a DX lens on a full frame body?

A: No, Micro 4/3 cameras have a 2x crop factor and Nikon DX cameras have a 1.5x crop factor. You will have a longer focal length when you attach a Micro 4/3 lens.

Q: 3. Will it work for an Olympus OM 65200mm? Also, a Nikon D70?

Q: 5. Will it provide infinity focus of oly 21mm3.5 Lens on Canon 6D?

Q: 6. Does this adapter work with pre AI lens Nikon F lens?

A: The Rayqual Lens Mount Adapter for Nikon F Lens to Leica M-Mount Camera allows you to mount all Nikon F-mount lenses on a Leica M-mount camera. However, the adapter does not support autofocus or camera-to-lens communication. So, you cannot control the aperture on Nikon G lenses that do not have an aperture ring.

Q: 7. Will auto diaphragm work with this adapter? I mean, can I focus the lens wide open and when taking the picture, the diaphragm will close to the stop down aperture?

A: My Hexanon lenses from my Konica camera adapt to my Nikon D100 camera, but I can't view through wide open aperture. It's not too inconvenient focusing in reasonable light because the focus indicator light still works. All other settings are set manually in conjunction with an external light meter. My main objective was to have the use of otherwise very good lenses.I hope this helped somewhat. PS B&H is very helpful; and they have great free instructional videos.

Q: 8. Can this adapter be used on the Beastgrip Depth Of Field MK2 to accommodate a Tokina SZ-X and or Sigma Pantel manual lenses? It doesn't have to be perfect.
