Displays
Shooting mode information
Pressing the INFO button displays an overview of the current camera configuration. The Mark IV does away with the super-detailed but essentially illegible settings list, instead just presenting a full-screen version of the information shown on the top display panel. This display isn't interactive in the way it would be on a camera with fewer external controls, instead a different option screen is brought up depending on which button has been pressed.

Record review & play displays
The Mark IV has a fairly standard choice of playback screens and, as usual for Canon DSLRs, these can be tailored to your tastes, including the option of whether overexposed areas 'blink' or whether the histogram display shows luminance or separate Red, Green and Blue data. The maximum number of images that can be shown in thumbnail mode is 9 (the same as the Mark III), which doesn't make great use of the new, higher resolution screen.

Nine image index 3 x 3 thumbnail display. Exposure and file number relates to currently selected image. Use the quick control dial or front dial to browse / jump. |
When browsing through images in the thumbnail views using the rear dial, images will 'scroll on' from the bottom right or top left corner (depending on the direction). The front dial can now be used to scroll through thumbnails a page at a time.
