Quick guide to enabling manual focus override on EOS R cameras

By default, Canon EOS RF lenses don’t have the instant manual-focus override feature enabled, as you find on the EF series. To enable this functionality, you need to change a specific menu setting in the EOS R camera. Follow these steps to activate manual focus override:

Steps to Enable Manual Focus Override

1. Access the AF Menu:On your camera, navigate to the AF menu. For the Canon EOS R5 and EOS R6, look for page AF 4. For other models, look through the AF menu pages for the following option:
2. Locate “Lens Electronic AF” option:Within the AF menu, locate the “Lens electronic AF” option.
3. Change the Setting:Set it to either:
   • “One-Shot -> enabled”. This enables the manual focus ring in One Shot mode only.
   • “One-Shot -> enabled (magnify)”. This does the same and includes a magnification option that enlarges the image during focusing. It allows precise focusing for stationary subjects. Note, however, this option can be vexing with moving subjects.

Using Manual Focus Override

Once enabled, you can use AF as usual, and the focus ring can now also be used for manual adjustments. However, the focus ring will only take effect when you hold the shutter button halfway, and the camera has locked focus in One Shot mode. Note, even with the Lens Electronic AF option enabled, the focus ring will still be ignored in Servo mode (Canon considers this counterintuitive).

To maintain manual override with the Servo mode, consider using the Back Button AF option featured on this site.
