How to Use Vintage Lenses on a Mirrorless Camera

The quick answer
To use a vintage lens on a mirrorless camera, identify the lens mount and your camera mount, then choose an adapter made for that exact combination. Attach the lens and adapter, enable shooting without an electronically detected lens if needed, and focus and set the aperture manually.
One of my favorite setups is a Sony a6000 with Canon FD lenses. I like the character these older lenses can give photos and video, and adapting them is a fun way to try different focal lengths without building a completely new camera system.

1. Identify the two mounts
First find the mount on the lens, not just its brand. Canon FD and Canon EF are different mounts. M42 is a screw mount, while a lens marked for Nikon may use a different mounting system. Check the exact lens model and mounting information before ordering.
Then identify the mount on your camera. Sony a6000 and NEX cameras use Sony E-mount; Fujifilm X cameras use X-mount; and Canon EOS M cameras use EF-M. Canon EOS R cameras use RF, which is different from EF-M. Check your exact model rather than choosing an adapter based only on the brand.
2. Choose the right vintage lens adapter
A mechanical adapter connects a particular lens mount to a particular camera mount and positions the lens at the appropriate distance from the sensor. Many old SLR lenses can be adapted this way because mirrorless cameras have a shorter distance between their mount and sensor, but not every lens and camera combination will work equally well.
For example, my Canon FD lens on a Sony a6000 needs an FD lens to Sony E-mount camera adapter. An EF-to-RF adapter is for a different combination and will not mount that FD lens.
In the video I used Fotasy adapters and liked their solid construction. These links from the video are all for Canon FD lenses, with a different camera mount on the other side:
- Canon FD lens to Sony E-mount camera
- Canon FD lens to Fujifilm X-mount camera
- Canon FD lens to Micro Four Thirds camera
- Canon FD lens to Canon EF-M camera
- Canon FD lens to Nikon Z camera
These aren't universal adapters. If your lens is M42, Nikon F or another mount, choose an adapter made for that lens mount and your camera. Confirm the listing, infinity focus, aperture operation and clearance for your exact lens and body. A focal reducer is a different kind of adapter and can change the effective field of view.
3. Attach the adapter and lens
- Turn the camera off. Remove the camera body cap and the appropriate lens and adapter caps.
- Attach the adapter to the camera and mount the lens to the adapter, following the adapter's alignment and locking instructions. FD locking rings and adapter controls vary by version.
- Make sure both connections are secure without forcing them. Support a heavy lens rather than letting its weight hang from the camera mount.
- Turn on the camera and take a test shot. Check focus at a nearby subject and at a distant one, and make sure the aperture responds as expected.
4. Enable shooting without a detected lens
A basic mechanical adapter usually has no electronic contacts, so the camera may report that no lens is attached even though the lens is mounted. If it won't take a photo, look for a setting such as Release without lens or Release shutter without lens and enable it.
The name and menu location depend on the camera. Sony's support guidance covers the setting for non-communicating lenses and adapters; consult your camera's manual for the exact path.
5. Focus and set exposure manually
With a manual vintage lens and a simple adapter, turn the lens's focus ring to focus and its aperture ring to change the aperture. Set shutter speed and ISO on the camera, and check the preview or a test image for exposure. The camera may not record the lens's aperture or model in the image information.
Take your time. I enjoy that slower process because it makes me pay attention to the shot. If your camera offers focus magnification or focus peaking, they can help you judge manual focus, though it's still worth checking the actual image.
What to check when buying an old lens
Look for clear photos of the glass and a description of haze, fungus, scratches and aperture or focus-ring condition. Ask whether the aperture blades move properly and whether the focus ring turns smoothly. Compare the full cost of the lens and adapter, and check the seller's return policy.
Vintage lenses differ in condition and character. Some produce flare, softer edges or distinctive backgrounds; others can be fairly sharp. For the lenses I've enjoyed and their tradeoffs, see my vintage lens recommendations.
Common problems
The shutter won't fire
Check the camera's release-without-lens setting. If the lens and adapter are meant to communicate electronically, check the contacts and compatibility instead of assuming the setting solves every problem.
The lens won't focus on distant subjects
Confirm that the adapter is designed for both mounts and is seated correctly. Adapter spacing and the particular lens can affect infinity focus, so check the manufacturer's compatibility information and test the setup.
The aperture doesn't change
Check the lens's aperture ring and the adapter instructions. Some FD adapters use a control or locking ring to operate the aperture mechanism. Electronic-aperture lenses may need an adapter with the appropriate control rather than a simple mechanical ring.
Frequently asked questions
Can every vintage lens be adapted to every mirrorless camera?
No. Many combinations work, but the mounts, flange distance, adapter design and lens coverage matter. Verify your specific lens and camera before buying.
Do vintage lenses autofocus on a mirrorless camera?
Traditional manual-focus lenses used with a basic mechanical adapter are focused by hand. Electronic adapters and autofocus-capable lenses are different cases, and features depend on the exact combination.
Will a vintage lens look the same on APS-C and full-frame cameras?
The lens's focal length stays the same, but an APS-C sensor captures a narrower field of view than full frame. The smaller frame can also show less of an effect occurring toward the edge of the image.
Do I need an expensive adapter?
Not necessarily. A basic manual adapter can be inexpensive, but the correct fit and reliable operation matter more than price alone. Check both mounts and what the adapter is designed to do.
