Electronic 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.
Face-Detection Focusing 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.
Image Stabilization Image stabilization reduces the effects of camera shake at long exposures and long focal lengths in street photography thus ensuring sharper photos.
