How do I know which extension tube fits my camera?

Ensure the Fotasy adapter's mount matches your camera's lens mount exactly. This adapter is designed for Canon EF and EF-S mount DSLR cameras. Always verify the mount type printed on the adapter and your camera body before purchase to ensure compatibility.

Will an extension tube reduce my image quality?

Extension tubes contain no optical glass, so they do not inherently reduce image quality. Image sharpness depends on the quality of the Olympus OM lens you attach and the precision of the adapter's fit. This copper adapter ensures a snug fit and infinity focus, preserving the optical integrity of your adapted lens.

Can I use autofocus with this adapter?

No, this Fotasy adapter does not have electrical contacts, meaning autofocus and automatic diaphragm functions are not supported. You will need to adjust focus and exposure manually. This allows for greater creative control and a more deliberate photographic process.

How to use Fotasy Olympus OM Lens to Canon EF/EF-S Adapter?

Attach the adapter to your Canon EF/EF-S DSLR camera body first. Then, mount your Olympus OM lens onto the adapter. Set your camera to Manual Exposure or Aperture Priority mode. Adjust focus and aperture manually on the lens and camera settings as needed for your shot.

Is this adapter compatible with Canon EOS R mirrorless cameras?

This specific Fotasy adapter is designed for Canon EF and EF-S mount DSLR cameras. It is not directly compatible with Canon EOS R mirrorless cameras, which use the RF mount. You would need a separate EF-to-RF mount adapter for mirrorless systems.
