Vastly more focus points
206 more focus points. The more focus points the more flexibility in picking which part of the scene to focus on. They also give the image sensor a better probability in identifying the right area of the scene to focus on in more automatic modes.

Faster photo autofocus due to a phase detection autofocus when shooting pictures
A phase detection autofocus is much faster than a contrast detection autofocus and allows sharper images.
Has an optical viewfinder
An optical viewfinder (or OVF) allows the photographer to compose a shot while seeing exactly what the lens sees. There is no time lag and they require no power - as opposed to electronic viewfinders which can drain battery life. They are also better in low light situations.
