Preparing the Camera
NOTES
• Turning on the image stabilization function of a lens may reduce the effective usage time of the battery pack.
When image stabilization is not necessary, for example if the camera is fixed to a tripod, it is recommended to
turn it off.
• Depending on the lens used, you may experience one or more of the following limitations.
- The lens model name may be shortened when displayed on the screen.
- You may not be able to focus manually when the focus mode switch of an EF lens is set to AF.
- You may not be able to use the focus preset function on an EF lens (super telephoto lenses).
- You may not be able to use the power zoom function on EF lenses with that function.
• This camera’s sensor is larger than the sensor size for which EF-S lenses are designed (APS-C). When using
EF-S lenses with this camera, you may notice peripheral illumination fall-off or vignetting (

• When using a compatible lens, you can use the > [
B
System Setup] > [Retract Lens] setting to retract
the lens automatically when the camera’s power is turned off with the lens's focus mode switch set to AF.
Using the EF-EOS R 0.71x Mount Adapter
• You can use the EF-EOS R 0.71x Mount Adapter to attach a compatible EF lens to the camera (when the
camera's sensor mode is set to [Super 35mm (Cropped)]/[Super 16mm (Cropped)]) and shoot video with an
angle of view equivalent to full frame. Additionally, you can use autofocus, peripheral illumination correction
and chromatic aberration correction. For details on compatible lenses, visit your local Canon website.
* Setting the camera's sensor mode to [Full Frame] causes vignetting.
• When using the EF-EOS R 0.71x Mount Adapter with some EF lenses, a frame that limits the AF range may be
displayed.
Updating the Firmware of a Lens/Mount Adapter
You can update the firmware of the lens/mount adapter attached to the camera (only in CAMERA mode). For
details about firmware updates, visit your local Canon website. The following example explains how to perform a
firmware update for lenses.
1 Download the lens/mount adapter firmware update file from the Canon website and save it on the root
directory of an SD card. Insert the SD card containing the firmware update into the camera's SD card slot 2
(
A
34).
2 Attach the lens/mount adapter you want to update and turn on the camera in CAMERA mode.
• Attach a lens also when updating the firmware of the mount adapter.
3 Select > [
B
System Setup] > [Firmware] > [Lens] or [Mount Adapter].
• The current lens/mount adapter firmware version will appear on the screen.
• If the menu option is grayed out, the attached lens/mount adapter may not support firmware updates or the
SD card used may not contain a valid lens firmware file. Check the lens/mount adapter and SD card and
repeat the procedure from the beginning.
4 Select [OK].
5 Select the lens firmware file (.LFU or .AFU file).
6 Select [OK].
• The firmware will be updated. Once in progress, the lens firmware update cannot be canceled.
7 When the confirmation message appears, press SET.
IMPORTANT
• Be sure to observe the following precautions while the lens firmware is being updated.
- Do not turn off the camera and do not remove the battery pack or other power source.
- Do not remove the lens/mount adapter.
- Do not operate any buttons or controls on the camera.
- Do not open the card compartment cover and do not remove the SD card.
