R5 EVF Screen is Completely "Overexposed" and unusable

katgrady — Tue, 17 Sep 2024 15:30:51 GMT

This is the 2nd time that this has happened since I bought my R5 and in both instances it began randomly in a session, without any changes in my settings etc. The first time it seemed to also randomly fix itself, so I have no idea how to replicate a resolution.

The issue: The viewfinder, when looking into it, is a very overexposed screen. The back preview screen is completely normal and indicative of the settings of my shots, and the subsequent recorded image is also normal.

What I have tried: Adjusting the EVF settings (brightness, color, you name it). Resetting ALL camera settings. Switching batteries, completing firmware updates, switching cards, switching lenses, I'm using authentic Canon LP-E6NH batteries....

I AM using an adaptor for my EF lenses, but have done so from the beginning.

Unfortunately, I seem to be the only one with this issue, as I have searched high and low in all forums and searches that I can think of.

Any insight would be greatly appreciated, as I prefer shooting with the viewfinder as opposed to the back screen.

Thank you1

Greetings,

I've had the EVF completely wash out when shooting into a bright backlit scene. I was at the beach and it was a few firmware releases ago. Don't remember which. I think I was in Av mode. It only lasted for a few seconds and it resolved on its own.

What firmware version are you running on your R5. I'm not suggested that is a fix for anything, I'm just asking?

Its an EVF, so it can be subject to lighting variance.

Hi Rick,

Thank you for taking the time to reply. Unfortunately, it has nothing to do with the lighting I'm in. It stays "overexposed" no matter where I am or what my settings are.

It actually remedied itself during an event I was shooting (after being unusable for the last several sessions I shot) and then started up again yesterday in the middle of a studio session, right between shots.

It's so bizarre. I haven't found any information at all - even with Canon.

I appreciate you taking the time to try to help!

Have a wonderful day.

Well now I can tell you you’re not the only one. I went to an event tonight and it happened to my evf. It’s completely blown out. Please tell me you’ve figured this out.
