Full details

This Urth Lens Mount Adapter is for photographers using Canon EF-M mount cameras who want to expand their creative options by using M42 mount lenses.

FAQs

Will autofocus work with this adapter?

No, this is a manual adapter. All electronic functions, including autofocus and auto-exposure, are not supported. You will need to manually focus and set your exposure.

Can I use lenses with a built-in aperture ring?

Yes, you can use M42 lenses that have a physical aperture ring. You will adjust the aperture directly on the lens.

What does 'light-sealed' mean?

It means the adapter is designed to prevent stray light from entering the camera body between the adapter and the lens mount, which helps maintain image quality and prevent unwanted flares.

Does this adapter support infinity focus?

Yes, the adapter is designed to allow focus to infinity, provided the original M42 lens was capable of focusing to infinity.

What material is the adapter made from?

The adapter is machined from hardened aluminum and copper, coated in an anti-reflection matte finish.

What is the warranty on this adapter?

This adapter is backed by Urth's lifetime warranty.

How do I clean the adapter?

Gently wipe the adapter with a soft, dry microfiber cloth. Avoid using liquids or abrasive cleaners.

Troubleshooting

Camera does not recognize the lens or refuses to take a photo.

Ensure the adapter is fully and securely attached to both the camera and the lens. Check if your camera has a 'release without lens' setting enabled in its menu; this is often required for manual adapters.

Image appears overexposed or underexposed.

This adapter disables electronic communication. You must manually set the aperture on the lens and adjust shutter speed and ISO on your camera to achieve correct exposure. Practice 'shooting through' the lens to get a feel for exposure settings.

Focus is inaccurate.

Use your camera's live view feature for precise manual focusing. Magnifying the live view can help ensure sharpness. Focus confirmation indicators in some cameras may not work with this adapter.

Adapter feels loose or wobbly.

Re-seat the adapter and lens, ensuring they are fully locked into place. If the issue persists, contact Urth support as there might be a defect.
