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. 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. Large Full frame (36 x 24 mm) sensor
Large sensor in Canon 5D MIV 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.
No Image Stabilization
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 Body
Due to the lack of sensor based Image stabilization, Canon 5D MIV users have to rely on lenses with optical IS in order to maximize the sharpness of their handheld street photography photos. Currently there are native Canon EF mount lenses with Image Stabilization for Canon 5D MIV.
