Not in the sense of using the LCD on the back panel of the camera. Essentially, the camera has TWO electronic display screens - one of them is the LCD panel on the back of the camera, while the other is a high-resolution one mounted in the viewfinder binnacle. If you want to use the traditional camera stance, holding the camera up to your eye to shoot, and blacking out stray light by looking into a viewfinder, this will be done exactly as it is done on a DSLR - except instead of looking optically off a mirror or through a prism and through the lens, you are looking at a very high res electronic display feeding off the main sensor which is looking through the lens.
A switch on the camera can select either electronic viewfinder or LCD - or you can have the camera set to switch to the viewfinder when your eye raises to the camera.
Whenever you see 'EVF' instead of 'OVF', it means the camera still has a viewfinder, but that it is electronic rather than optical.
