EOS R5 C not taking photos

[NEWYORKGM]

I traveled to Brooklyn this past Labor Day to shoot videos and take pictures. To my surprise, when I tried to use the camera to take photos, it wouldn’t work, even with the self-timer set. What should I do? I own several different Canon cameras, but the R5C is proving to be quite frustrating.

  Did it turn on?  Did you check your battery? 

[NEWYORKGM]

Yes, the battery is on. I'm even using a battery grip that allows me to add extra battery.

also, the apeture slider remains on F00 and when I press the shutter button, I see a flashing red camera icon on the monitor.

An aperture reading of "F00" suggests that the camera can not communicatre with the lens.  To help you more, we're going to need to know what lens you're using.  But basically:

• If the lens is a mechanical lens, with no electronic contacts, then you need to set the camera to take pictures with no lens attached.  There's a menu setting for this.
• If the lens is a proper Canon RF lens, or an EF lens and you're using a correct adapter, then it seems that there's something wrong with the electronic contacts, or the lens is broken.
• If the lens is an electronic lens for another make of camera -- like Nikon -- then there's no way it can work.

Also if you are using an EF lens with an adapter, make sure that the adapter is locked on securely to the camera body and that the lens is securely on the adapter.   Sometimes if one didnt click or wasnt tghten till it locked than you won't have  good connectivity and the camera won't work.

Greetings,

Since we aren't there to see what you have in hand, we need more information to help.  Great that you own several Canon bodies. 

For the time being, remove the battery grip.

What's installed or connected to the body?

Lens is? 

What brand, model and type(s) of storage media are installed?

Canon battery?

I assume the camera powers on since you mentioned self-timer mode.

What shooting mode are you in?

Describe the behavior for us.  What you observe.  Does the camera focus when the shutter is half-pressed?  "Wouldn't work" is not much to go on.  🤔  Help us, help you.

Thank you all for your incredible support! After I removed and reconnected the adapter, the camera magically started working again. I truly appreciate your thorough feedback. If any of you live in New York City, I would be more than happy to take lessons from you. Please feel free to email me at [email address removed per community guidelines]. Thanks once again!
