My EOS R5 has the aperture stuck at the lowest F of my lens and is unable to change to other value

[Brokencanonr5]

Is this problem common to many R5?

Greetings

It's not typical.  Might it be an incorrect setting, hardware incompatibility or failure?  Does this happen with any lens or just one?  Take a look at your custom functions.  C.Fn.. There is a setting that allows you to specify a range for selectable apertures.  Resetting your camera settings is another option.

I've only seen one other recent report of this type of problem and it was a problem with a menu setup.

You don't say how your are trying to make adjustments to the aperture that is stuck. Have you looked at the button/dial customization menu to make sure they are set up?

Camera/Orange menu
Screen 3

If you can't find/resolve the problem I am confident Canon can assist you, go right to the source, save yourself some time and frustration. 800-385-2155 or 800-652-2666

Did you change the setting for the aperture range in the custom functions menu, C.Fn2 there is a setting labelled Set aperture range, and if it is changed from the default there will be a blue coloured asterisk on the right. If this is showing then you might want to change this back to the defaults which are Max. aperture 1.0 and min. aperture 91.

Check this page of the manual, you need to scroll down a little to find the Set aperture range section.
