The Nokia Lumia 920 has an 8.7MP rear camera and a 1.2MP front-facing camera. Its camera sports a floating-lens technology and offers optical image stabilization which is a first for smartphones. The camera gives you two interesting features called Smart Shoot and Cinemagraph.
Many times, specially in very crowded places or tourist hotspots, while clicking photographs, you end up capturing a random stranger who just passes between the camera and the subject. With the Smart Shoot, the Lumia phone detects any motion in the frame, and selects the area which can be removed from the frame.
Cinemagraph basically allows you to animate your images - it is like a glorified GIF. Glorified because you can adjust the areas that you want to be animated. Quite a nifty feature.
