As Canon’s newest line of cameras, the EOS R mirrorless camera and its corresponding lenses boast some of the latest and greatest technology. However, many photographers are wondering whether they can use their older EF lenses on the new RF mount. The answer is yes… with a few caveats.
First, you’ll need an adapter in order to physically attach the lens to the camera. Second, not all EF lenses will work with all RF cameras- there are some incompatibilities between certain models. Finally, even when using an adapter, you won’t be able to take advantage of some of the newer features available on RF lenses, like control over aperture or image stabilization.
- Select an EF lens that is compatible with your RF camera mount
- With the lens mounted on the camera, set the switch on the lens to the “EF” position
- Set the aperture ring on the lens to the “A” position
- Press and hold down the shutter button half-way to engage AF (autofocus)
- Take your picture!

Canon Mirrorless – adapting EF lenses VS native RF?
How Well Do Ef Lenses Work on Rf?
In short, EF lenses work great on RF. There are a few things to keep in mind, however. Firstly, because the mount is smaller on RF cameras, the image circle produced by EF lenses will be slightly cropped.
Secondly, due to the different distance between the lens and sensor on RF cameras vs EF cameras, there may be some slight vignetting at the edges of the frame. Finally, because of the way RF lenses are designed to work with the mirrorless design of RF camera bodies, using an EF lens on an RF body may cause some autofocus issues.
Can You Use Ef Lenses on Rp?
Yes, you can use EF lenses on RP. You will need an adapter in order to do so, but once you have the adapter, you’ll be able to use your EF lenses just as you would on any other camera body. There are a few things to keep in mind when using EF lenses on RP, however.
First, because the sensor is smaller on RP, you will get a 1.6x crop factor. This means that your field of view will be narrower and your images will appear slightly zoomed in compared to if you were using the same lens on a full-frame camera body. Second, autofocus may not be as accurate or fast as it is with native RF lenses.
So if you’re shooting action or anything else where autofocus is critical, it’s best to stick with RF lenses. But for most other shooting situations, using EF lenses on RP is a perfectly viable option.
Can You Use Ef Lenses on Mirrorless?
Yes, you can use EF lenses on mirrorless cameras with the right adapter. The Canon EOS R system uses an RF mount, which is compatible with EF and EF-S lenses when used with an adapter. Other mirrorless camera mounts include Sony E-mount, Micro Four Thirds, and Nikon Z-mount.
Each of these has adapters available to allow for the use of different types of lenses.
Is There an Ef to Rf Adapter?
No, there is not an EF to RF adapter. The two mount types are incompatible. Canon EF lenses use a bayonet mount while RF lenses use a much larger diameter screw mount.

Conclusion
If you’re a Canon shooter, you may be wondering if you can use your EF lenses on the new RF mount. The answer is yes… and no. Here’s a breakdown of what you need to know.
Canon’s new RF mount is designed for their mirrorless cameras, and while it’s possible to physically mount an EF lens on an RF camera, there are a few things to keep in mind. First, because the flange distance (the distance between the lens mount and the sensor) is different on EF and RF cameras, you’ll need an adapter to make things work. And second, because of that same flange distance difference, using an EF lens on an RF camera will result in a slight loss of image quality.
So, if you’re looking to use your Canon EF lenses on a Canon RF camera, it can be done… but it’s not ideal. You’ll get better results by using native RF lenses or adapters that allow you to use other types of lenses (such as Sony E-mount lenses) on your Canon camera.
