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.

To get a better idea of what I am talking about, take a look at the to of the R6, not the R6M2.

Those controls weren't an issue if, say, I first used the touchscreen to pinch and initiate zoom mode that way.  It's only the use of the AF Point Selection button (with the blue magnifying glass below it of course) that wasn't working to initiate zoom mode. In other words, the only thing I couldn't do was initiate zoom mode. The rest was fine.

I've started recustomizing and am about done. Zoom button still works. Really strange.

Glad to hear there was a positive outcome.

The [MAGNIFY] button always worked.  It would seem that the initial playback magnification and initial zoom magnification are the same.  When the two initial settings are the same, then pressing the [MAGNIFY] button seems to have no effect.  

Combine the above with the default [ZOOM] control no longer being the Main Dial, one can get the impression that [MAGNIFY] is not working.  

Like I said, I ran into a similar issue with the R6M2.  I would press [MAGNIFY] and the display would not change, which was fine.  My DSLRs can exhibit the same behavior.  But, when I tried to change the zoom factor with the Main Dial, then nothing changed.  

[EDIT] It would seem like the camera would not enter zoom playback mode, when it was!  The fact that you can zoom using the touch screen confirms that camera entered zoom/magnify mode.

Nothing changed because I was using the incorrect control to change the zoom factor.  The default zoom control wasn’t the Main Dial.  I hate to sound cliche, but I discovered this difference by reading the Destruction Manual.

I realized that I needed to use the [Quick Control Dial 2] to control zoom factor, instead of the Main Dial near the Shutter Button.  I tested it.  Sure enough, the [QCD 2] button changed the zoom factor.  Getting used to this new control is going to be an uphill learning curve and adjustment, for me.

I went into the Custom Control Menu and changed this setting.  I can now use the Main Control Dial to control the zoom factor, just like I did on my DSLRs.

I definitely think it is either a bug or not programmed in a good way. I could replicate the behaviour: Setting the magnify/focus point button to any other function but the default "AF point selection" disables the magnification function. According to the setting in shooting mode the button either does nothing (for exmple "direct AF area selection") or sets the camera from play mode back into shooting mode (for example "direct subject selection"). Only with the default assignment does it act as a magnify button in play mode. Interestingly, setting any other button as a magnify button also does not work as long as the focus point/magnify button is not set to ist default operation as "AF point selection". 

In a few words,  the reprogramming of the button in shooting mode will lose its function as a magnify button in play mode. 

Please consider this in one of the next firmware updates. I think it is definitely a bug. Keep in mind, that no one other button can be programmed as magnify button as long as the AF Point/magnify button is not at its default setting.

Your observations and conclusions are incorrect.  Please refer to my explanation of how the Zoom button functionality works just above.  

The bottom line is that users are using the wrong control to magnify the image.  The main wheel does not control zoom and neither does the rear wheel on the rear panel on camera models that have one.

The advanced R series bodies add another secondary wheel control, one which does not appear on DSLRs.  In the case of the R8, this control is integrated into the On/Off switch.  This secondary wheel is the default control for adjust zoom magnification.

There is a menu option that allows users to select which user control wheel is used to control zoom magnification.  I would suggest to some users to change this to be the Main Wheel.

[Waddizzle]

After spending some time to read the User Manual the issue is not a firmware bug.  The issue is knowing which is the correct user control to use to control zoom magnification.

After pressing the [MAGNIFY] button, the default control to use to control zoom magnification is the wheel that is integrated into the [ON / OFF] switch.

Users have the menu option to select this wheel, or to use the main wheel as you would with a DSLR.  I programmed my camera to use the main wheel like my DSLRs.

The users are not using the wrong control to magnify the image. First, it is designated with blue magnifying glass, so this is surely the right button to use in play mode to magnify the image. Blue colour = function in play mode. Second, in the R8 user manual is explained, that this is exactly the button to be used. I consulted the user manual before googling and coming for help here. How can it be that this is the wrong control? There is no sense in losing the magnifying function once the default operation in play mode is changed. Understanding this is so easy. 

But I made a mistake too: although one can assign one of the 4 direction dials to be used for magnification in play mode it does not work, no matter how the "AF point/magnify" button is set. Although this is irrelevant for me I find it highly confusing. 

So to keep the only button intended for magnifying images in play mode I should not change its default shooting operation setting. Of course this makes no sense. 

I do not want to use a dial for initial magnification in play mode either. I tried to implement your suggestion changing dials but there is not such an option in the R8 other than reverse the operation in shooting mode. No way to set which dial should be used for magnification.

Are you sure that you refer exactly to the R8? If yes which menu item is it?

I have told you which control that you should use.  The [MAGNIFY] button puts the camera into magnify mode.  

Use the main control wheel to zoom in or out of the image.  Use the buttons that you keep trying to reprogram to move the magnified area around the image.

You say the you do not want to use the main control wheel to zoom in and out.  I have no response for that.  Good Luck!

The [MAGNIFY] button puts the camera into magnify mode. 

This is not what the user manual say. As much as I appreciate your quick response and trying to help I am afraid you do not refer to the R8. And you ignore my findings.

In respect to the R8 your suggestion simply does not work. Again, following examples, just freshly reproduced: If the "magnify/AF point" button is set to "direct select of sub to detect" pressing it in play mode sets the camera back in shoot mode, so how should I use a dial to magnify? If the button is set to "Direct AF area selection" pressing it in play mode does absolutely nothing. Both dials keep scrolling through the images, no magnification happens.

There is no option in the R8, to set a dial for magnification. Once magnified I can use a dial to change the magnification, this works fine. But the initial magnification is the problem here.
