Optical Built-in Viewfinder
Using a viewfinder during a street photography shoot allows the photographer to stabilize the camera and reduce the camera shake since it is closer to the body. Besides, it comes handy where LCD screens are very hard to read under bright sunlight. Live-view
Live view lets you take photos without using the viewfinder which makes you less obstrusive and this works very well during street photography where you don't want to get people's attention. Large Full frame (35.8 x 23.9 mm) sensor
Large sensor in Leica M10 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 Leica M10 is a good combination of relatively small size and good handling camera, without giving the impression of a professional camera.
No Image Stabilization
