| p.2 #13 · 1DX/5D3 odd intermittent playback glitch explained |
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 recent image shot, you can't scroll to another image, unless you hit 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 actually 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.
