Product Information

Full details

This Urth Lens Mount Adapter is for photographers looking to combine vintage M42 mount lenses with modern Micro Four Thirds (M4/3) cameras. It unlocks a vast array of new creative possibilities by allowing you to use lenses not originally designed for your camera system, offering a significant benefit in lens selection and creative control. However, it's important to note that this is a manual adapter, meaning electronic functions like autofocus and auto-exposure are not supported, requiring manual adjustments for focus and exposure.

FAQs

Will autofocus work with this adapter?

No, this is a manual adapter. Electronic functions such as autofocus and auto-exposure are not supported. You will need to manually focus and set exposure on the lens and camera.

Can I use lenses with a 'P' or 'A' setting on the aperture ring?

Yes, you can use lenses with these settings. For 'A' mode, you typically set the lens to the aperture ring's 'A' position and then select the desired aperture on the camera body. For manual control, set the aperture directly on the lens ring.

Does this adapter allow for infinity focus?

Yes, the adapter is designed to allow for infinity focus with compatible lenses and camera bodies.

What types of M42 lenses can I use?

You can use any lens with an M42 screw mount. This includes many classic lenses from brands like Pentax (Takumar), Carl Zeiss, Helios, and others.

Does the adapter affect image quality?

The adapter itself is designed with an anti-reflection matte finish to minimize internal reflections and light loss. Image quality will primarily depend on the quality of the M42 lens you are using.

How do I clean the adapter?

Use a soft, dry microfiber cloth to clean the mounting surfaces. Avoid using liquids or abrasive materials.

What is the warranty on this adapter?

This Urth adapter is backed by Urth's lifetime warranty.

Troubleshooting

Adapter doesn't mount securely to the camera.

Ensure there are no obstructions in the camera's mount or on the adapter. Realign the mounting indicators carefully and try again. Check if the camera model is listed as compatible.

Lens doesn't screw into the adapter properly.

Verify that you are using an M42 mount lens. Ensure the lens's M42 threads are clean and free of damage. Align the lens's mount indicator with the adapter's indicator.

Image is consistently underexposed or overexposed.

This is expected behavior for a manual adapter. Manually adjust the aperture on the lens and/or the shutter speed/ISO on your camera. Use your camera's light meter or take test shots to achieve correct exposure.

Focus is difficult to achieve.

Utilize your camera's focus peaking or magnification features. Practice manual focusing; it may take some time to adapt if you are used to autofocus.
