The 1-Euro coin has a diameter of 23.25mm.

The EOS R's image sensor has an effective resolution of around 31 megapixel. The resolution is far above average and will easily be sufficient for years to come. Photos with this resolution can easily be printed in A2 size or larger, even if unwanted parts of the photo have to be cropped.

The EOS R features a mechanism for automatic sensor cleaning.

Exposure Modes

The EOS R supports all general exposure modes.

The Canon allows spot exposure for the difficult occasion.

Auto Focus Properties

The EOS R's auto focus processor uses 5955 AF points (or sensors). A basic rule of thumb says that the more AF points you have, the better. More AF points mean a better chance to have a point at the location of interest in a scene, a big plus in challenging situations (e.g. when panning the camera).

Manual focus is also possible with the Canon, a plus in tricky situations or for some creative freedom.

Flash Specs

The EOS R doesn't feature a built-in flash. That is not unsusual in this camera category.

A flash or a trigger for remote flashes can be attached to the Canon's hotshoe.

Display Specs
EOS R display and touch screen

The EOS R features a monitor with a diagonal of 80.00mm (3.1 in.) and a resolution of c. 2.10 megapixel. A resonable value that will make it easy to evaluate images directly in-camera.

The camera's display is articulated, a plus for selfies and other challenging situations.

The EOS R's monitor can work as a touch screen, just like a smartphone. That can be very useful, for example to pick AF points, but keep in mind that touch screens usually don't work when wearing gloves.
