Product Information

Full details

This Urth lens adapter is designed for photographers who want to use vintage M42-mount lenses on their modern Sony A (Minolta AF) mount cameras. Its key benefit is unlocking a vast range of new creative possibilities by combining classic optics with contemporary camera bodies. A key caveat is that electronic functions like autofocus and auto-exposure are not supported, requiring manual control. The adapter is precisely machined for a secure, light-sealed fit and is constructed from durable aluminum and copper with an anti-reflection finish. Purchasing this adapter also contributes to Urth's tree-planting initiatives.

FAQs

Can I use autofocus with this adapter?

No, this adapter does not support any electronic functions, including autofocus. You will need to focus manually.

Will I be able to control exposure automatically?

No, automatic exposure control is not supported. You will need to use your camera's manual exposure settings (shutter speed, ISO) and set the aperture on the lens itself, if it has an aperture ring.

Does the adapter record lens information (EXIF data)?

No, because it's a purely mechanical adapter, it cannot communicate with the camera body to record lens model, aperture, or focal length in the image's EXIF data.

What is the construction material of the adapter?

The adapter is constructed from hardened aluminum and copper, featuring an anti-reflection matte finish.

How does purchasing this adapter contribute to planting trees?

Urth partners with organizations to plant trees in areas affected by deforestation for every product purchased, including this adapter.

Can I use this adapter with Sony E-mount cameras?

No, this adapter is specifically designed for Sony A (Minolta AF) mount cameras. For E-mount cameras, you would need a different adapter.

Troubleshooting

Adapter does not lock onto the camera.

Ensure the adapter's mounting flange is clean and properly aligned with the camera's mount index. Check for any obstructions on either surface.

Lens does not attach securely to the adapter.

Verify that you are using an M42 mount lens and that it is correctly aligned with the adapter's mount. Ensure the lens's M42 mount is clean.

Images appear blurry or out of focus.

Confirm that you are manually focusing correctly using your camera's viewfinder or live view. Ensure the adapter is fully seated on both the lens and camera.

Light leaks visible in photos.

The adapter should provide a light seal. If leaks are present, re-mount the lens and adapter to ensure a snug fit. Inspect the adapter for any damage.

Pros and Cons

Pros

  • Expands lens selection significantly by allowing use of M42 lenses.
  • Durable construction ensures a reliable connection.
  • Precise fit prevents light leaks and maintains image quality.
  • Supports Urth's environmental mission through tree planting.
  • Simple to attach and detach for quick lens changes.

Cons

  • Does not support electronic functions (autofocus, auto-exposure, EXIF data).
  • Requires manual focus and exposure adjustments for every shot.
  • May introduce vignetting or focus shift depending on lens and camera combination.
  • Compatibility needs to be verified for specific M42 lenses, especially those with protruding rear elements.

Setup, Compatibility & Care

Setup:

  1. Ensure both your M42 lens and Sony A mount camera are clean.
  2. Align the adapter with the mounting index mark on your Sony A camera body.
  3. Gently twist the adapter clockwise until it clicks into place.
  4. Align the mounting index mark on the M42 lens with the mark on the adapter.
  5. Gently twist the M42 lens clockwise until it locks onto the adapter.

Compatibility:

  • Lenses: This adapter is designed for M42 screw-mount lenses.
  • Cameras: Compatible with all Sony A (Minolta AF) mount digital and film cameras.
  • Limitations: Electronic functions of the lens are not supported. Some very large or internally complex M42 lenses may not physically fit or could interfere with the camera's mirror mechanism (though this is rare for Sony A mount).

Care:

  • Clean the adapter's mounting surfaces with a soft, dry microfiber cloth.
  • Avoid exposing the adapter to excessive moisture or dust.
  • Store the adapter in a protective case or pouch when not in use.
