DXO mark sensor scores

The DXOmark rankings indicate that the Canon EOS M camera has above average color depth performance, which refers to the number of colors the sensor can distinguish. Additionally, its dynamic range is also average, allowing it to retain low amounts of details in both bright and dark areas of a scene. The camera's low light ISO performance is poor, which is an important factor to consider if you plan to use it in dimly lit indoor environments or at night. Overall the image quality of the EOS M is below average

Crop Factor

Camera crop factor (or focal length multiplier) refers to how a camera's sensor size affects the apparent field of view of a lens. Crop factor is determined by comparing the size of a camera's sensor to that of a full-frame sensor, which is a standard reference size for camera sensors.

Connectivity, storage, battery

Battery Life230 shots
Battery ModelLP-E12
Wireless Connectivity


The Canon EOS M supports SD/SDHC/SDXC with 1 slots for storage. This may suffice for everyday use. However, for professional applications such as wedding photography, it is not recommended as a memory card malfunction could lead to the loss of all footage.


The Canon EOS M uses the LP-E12 model of battery pack. This is rated for 230 shots shots which is high. If you intend to take photos or record videos for an extended period, it might be a good idea to bring along additional batteries.

Photography Features


The Canon EOS M does not have a built-in flash, but it does offer a flash shoe that allows you to attach external flashes. This provides more versatility in your lighting choices.


The Canon EOS M boasts a maximum mechanical shutter speed of 1/4000s, which is ideal for shooting fast-moving subjects in bright environments, such as in sports photography. Faster shutter speeds enable you to freeze the action and capture every detail, making it easier to get the perfect shot.

With a continuous mechanical shutter speed of n/a or an electronic shutter speed of n/a, this camera is not capable of capturing the perfect moment more easily, making it not as suited for wedding, sports, and wildlife photography. Higher shutter speeds make it easier to capture fast-paced action, ensuring that you never miss the perfect shot.


The Canon EOS M includes two autofocus (AF) systems: contrast detection and phase detection, with 31 number of focus points.

While contrast detection is generally more accurate and precise, phase detection autofocus is faster and more effective in most situations, particularly when photographing moving subjects.

Phase detection autofocus works by dividing the incoming light into pairs and then analyzing how they intersect on the camera's sensor. This method allows the camera to determine not only if a subject is in focus but also the direction and distance needed to adjust the focus to achieve perfect sharpness.

On the other hand, contrast detection autofocus works by analyzing the contrast of an image and adjusting the focus until the highest contrast is detected. While this method is very accurate, it can be slow, especially in low light conditions or when photographing moving subjects.
