Face detection focusing mode is very helpful in the street scenes where you focus on a face, since you can concentrate on framing and other adjustments while the camera handles the focus for you. Tilting LCD Screen
An articulated screen gives you the flexibility to shoot in non traditional positions such as waist level, which helps you to be more creative and unobtrusive in the streets. Large APS-C (22.3 x 14.9 mm) sensor
Large sensor in Canon M3 ensures a good low light image quality compared to smaller sensor, and it also provide shallow depth of field and a nice blurry background when needed.
Medium sized Body
Mirrorlessbody of Canon M3 is a good combination of relatively small size and good handling camera, without giving the impression of a professional camera.
No Image Stabilization
