R5 - Randomly will not take a photo

[Bear2112]

I have a Canon R5 and on occasion it will not take a picture when turned on. Normally I hear the sound of the "click" inside the body when I turn the camera on and I know I am good to go, but on random occasions I don't hear that click and I see nothing but black through the view finder. Eventually I can get the camera to work by switching modes and/or turning the camera on and off, but this can be very frustrating. Does anyone else have this issue? And before people ask...

YES, the battery is fully charged

YES, my SD card(s) are fine

YES, I have updated the camera's firmware

NO, It does not matter which lens I am using (though I I should note I am using an EF adapter).

YES, I have meticulously cleaned all the contacts on the camera and lenses.

and NO (LOL) the lens cap is not on.

Is there something in the camera settings I should check?

Is the EF adapter a Canon product?

Yes

Comments declaring what the problem is not always get my attention, especially when no details are provided to support the comment.

What brand and capacity of SD cards are you using?  

Do you only use an SD card, without a second card?

[Bear2112]

Lexar Professional Silver Pro 128GB and a Lexar 256GB Professional CFexpress Type B Silver Series Memory Card.  I typically have both in the camera, using the Type B as the Primary.  Occasionally I will shoot with just the 128GB SD card though.  I've had the situation I described happen with both.

And when I say this "Randomly Happens" I do mean it is random.  I may turn the camera on, take several pictures, turn the camera off, turn it back on 10-15 minutes later and the camera won't take a picture.  Other times it happens when I first turn the camera on.  No error messages.

What lenses are you using?  

What are you trying to photograph?  

What are the shooting conditions?

Tell us how to reproduce the issue.

Have you tried to contact Canon Support for assistance?

[Bear2112]

I don't think I can explain the situation any better.  You seem to be more concerned with my explanation than the problem at hand.  What lenses are you using? It's like I said - all of my lenses 24-105mm Canon, 70-200mm Canon, 100mm canon macro...etc. etc.

What are you trying to photograph?  Anything, again, it happens randomly.

What are the shooting conditions?  All types, sunny, indoors, outdoors, cloudy, close, far...

AGAIN...I turn on the camera and sometimes I hear the click of shutter opening and sometimes I don't and the screen and viewfinder are dark and I can't take a picture.  It's okay if you don't have any idea.  I am just looking for someone who has had the same experience and found a reason/solution.  "Have you tried to contact Canon Support for assistance?", clearly that'll be my next option, I just thought I'd try here first.

“ I don't think I can explain the situation any better.”

I am inclined to agree. That’s why I asked you about Canon Support.  I suggest that you arrange to have your gear checked out by Canon.  I don’t think many EF lenses are still supported by Canon.
