Bug Report: EOS R8 Magnify Button Doesn't Work in Image Playback - Firmware 1.0.0

[SometimesSepia]

When viewing images in playback, the magnify button doesn't work. I think this is a firmware issue because this button is also used for AF point selection when in shooting mode and works just fine. I am still able to zoom in on the images in playback using the touch screen. Canon EOS R8 Firmware 1.0.0. Please help.

Tell us what happens when you press the magnify button.  You need to use other controls to change the magnification factor.

Nothing happens when I press the magnify button on the R8. The image doesn't zoom in at all. I'm familiar with EOS RP where you press the magnify button and use one of the wheels to control the magnification factor.

Hi - I just purchased my R8 and am having the same issue. Was glad to see someone else mention it because I thought I was doing something wrong.  Likewise, my button is otherwise functional so this must be a playback bug.

I'm a new owner of a Canon R8 and my magnify button works just fine during playback. I have Magnification set to 10x on sheet 3 of the Playback menu. I noticed that one of the options is "Actual Size" so maybe your settings are set to this option?

Greetings,

One of our next recommendations would be to perform a settings reset on the camera and see if the behavior can be reproduced.  In many cases, its a setting or particular combination of them that "appears" to cause unexpected behavior. This only takes a few minutes to confirm.

Hi - Yes I took a good look at those settings. I'm at 2x.  I've tried other magnifications as well (and a different initial zoom area via the other option) but no luck.  Thanks for the idea though.

Hi Rick - Yes, I was wondering if there could be some other setting (like a custom button, though I've not assigned anything different there) causing the conflict.  I'll look around a bit more and otherwise reset, and will then report back.  Thanks.

Hi again - 

So, resetting just the "Basic Settings" did not fix the issue.  However, resetting most of the "Other Settings" (I held back on resetting copyright and communications preferences) did fix it. 

I probably should have done those one at a time to see exactly which category cleared it, but perhaps I'll be doing it again once I get everything set up the way I want it , unfortunately.  If so, I'll do them one at a time.

Does seem like a bug since there's no option (that I can think of) that should be disabling that zoom function.

Thanks for your guidance on this.

I ran into the same issue with my R6 Mark II.  Which control are you using to zoom/magnify a playback image?

The default button for zoom control is not the same as a DSLR.  I just took a look at the rear and top of the camera body at B&H.  The [ON / OFF] switch looks like it is a thumb wheel.  That is the default control for zooming on the R6M2, not the Main Wheel by the shutter as it would be on a DSLR.
