Solution

Camera operations are essentially the same as for the EOS R. Refer to the included EOS R Instruction Manual (booklet). Additionally, you can download the EOS R Advanced User Guide (PDF fi le) from the Canon website.
Before shooting, check for any EOS Ra news on the Canon website.
Display in magnifi ed view switches from approx. 1× to 5× to 30×, which differs from maximum magnifi ed view on the EOS R.
When using autofocus (AF) to focus, consider using magnified view to check the image.
More exact focusing is possible by using magnifi ed view with manual focus (MF).
Even if : Retract lens on power off] is set to [Disable], focus reset operation (lens retraction followed by extension) may occur automatically when the power switch is changed from <OFF> to <ON>, depending on the lens used. If focus reset operation occurs, recheck the focus before shooting.
Irregular colors may occur under some shooting conditions in long exposures and at high ISO speeds.
Zooming during bulb exposures may cause a loss of focus. Use a shooting mode other than [BULB] if you will zoom during exposure.
Focus may not be adjustable during bulb exposures, even by turning the lens focusing ring. Use a shooting mode other than [BULB] if you will adjust the focus during exposure.
Noise in your shots may increase due to image sensor heat if, for some time before shooting long exposures, you record movies or leave the camera in standby.
Noise will increase when taking a long exposure, or shooting repeatedly.
It is recommended that you take some test shots to check in advance how noise increases in the image.
Battery consumption increases when you mainly shoot bulb exposures. Carrying a spare battery is recommended. If household power is available, consider using AC Adapter AC-E6N and DC Coupler DR-E6. Note that continuous bulb exposure shooting for approx. 7 hr. 30 min. is possible with a fully charged Battery Pack LP-E6N at room temperature (23°C / 73°F).
When using a telescope, set : Release shutter without lens] to [Enable].
You can use the same software as for the EOS R. For details, refer to the EOS R Instruction Manual (booklet) or EOS R Advanced User Guide (PDF fi le).
