In additional EOS M was introduced by Canon in July 2012. It belongs to the Mirrorless Cameras category.

Canon is well-known and shouldn't require further introduction, please see our manufacturer's page for more digital cameras by Canon.

Also EOS M has a APS-C CMOS sensor with size of 22 x 15 mm² (0.88" x 0.59").

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

The EOS M's image sensor has an effective resolution of around 18 megapixel. That's roughly average and will be sufficient for most purposes. Photos with this resolution can easily be printed to A3 or A2 size.

The EOS M features a mechanism for automatic sensor cleaning.

Viewfinder Properties

The EOS M does not come with a built-in viewfinder. The camera's display is used to compose the photo. That can be cumbersome in broad daylight.


The EOS M's shutter speed varies from 1/4000s to 30s.

Max. shutter speed1/4000s
Min. shutter speed30s
Sensitivity Properties

The EOS M's sensitivity is from 100 ISO and 12800 ISO.

Also, Canon's sensitivity can be boosted to 25600. Therefore, ISO boosting will lead to growth noise.

Min. sensitivity100 ISO
Max. sensitivity12800 ISO
Boost25600 ISO
Exposure Modes

The EOS M supports all general exposure modes.

The Canon allows spot exposure for the difficult occasion.

Auto Focus Properties

The EOS M's auto focus processor uses 31 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 M 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 M display and touch screen

The EOS M features a monitor with a diagonal of 77.00mm (3.0 in.) and a resolution of c. 1.04 megapixel. That's about average.

Unfortunately, the EOS M's monitor is not articulated. That can make it tricky to frame your subject in some situations, e.g. when taking selfies.

The EOS M'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.
