Canon EOS-1DX and EOS-5D Mark III image review glitch explained

Here’s another glitch/bug with the Canon EOS-1DX (and shared by the 5D Mark III):

Immediately after creating an image and during the time in which it automatically appears on the camera’s display, if you zoom in to check the focus, then try to scroll to a neighbouring image, the camera will remain locked on the image just captured.

The inability to scroll to other images is caused by turning on auto image review to any of the timed durations, or the hold option. I believe this setting is on by default and is found in the red Shoot3 tab “Image review.” Therefore any 1DX or 5DIII taken straight out of the box should display this behaviour.

The solution is to turn off image review, which will allow you to directly zoom into the image by pressing the magnify button and scroll to neighbouring images at any time, no matter how soon after capture. This also works if you have programmed the Set button to initiate image zoom, as I have.

This raises the question of whether this behaviour is a glitch, or whether it’s intentional.

After giving it some thought, I think it’s intentional. With auto image review on, after taking a photo, when that photo first appears, and if you try to scroll to another image, it just disappears and the screen goes black (and actually changes your shutter speed or aperture (or whatever you have the rear dial assigned to do in shooting mode). The logic is that the photographer’s priority is shooting, not review, because if the photographer really wanted to review images, s/he’d hit the playback button and consciously switch out of image capture mode. If during initial auto image review you press the playback button, you can scroll through images, whether zoomed or not.

I don’t have my 1DIV handy, but pulled out a 1DIII for comparison. Same basic principles with it. Auto image review only allows you to see the most recently captured image. You can’t scroll to another image, unless you press the playback button. Also, during auto image review, you can’t zoom in. The screen goes black because the camera thinks you want to set the AF point. I.e you’re still in image capture mode rather than image review mode.

I think the 5DIII/1DX (never tried the 7D) are probably the first to allow us to zoom into the image during auto image review. Previous cameras forced us to hit the playback button first.

When auto image review is turned off, the logic is that the photographer doesn’t want to see the images, therefore, if one presses the zoom (or assigned the set) button, one is consciously deciding to review images and may want to scroll through more than just the most recent one.
