Rear of camera controls
The rear of the Coolpix 3100 continues its modernized, round 'comfortable' styling, the few buttons are intelligently placed with clear labeling. This is a camera aimed at novice users and shouldn't therefore overload them with visible controls.

Enters the Coolpix 3100's play mode, despite being a single press button this mode is not 'shooting priority', you must press this button again to return to record mode (which is a shame and must be easy to implement). Also you can not (unlike some other digital cameras) use this button to power the camera on into play mode.
