The Coolpix 7900 does its best to prevent you taking bad shots.
Blur Warning is to let you know when camera shake or hand shake has affected a shot - but we found far too many blurred shots still slipped past the sensor's eye.
D-Lighting compensates for insufficient flash or excessive backlighting. When tone is adjusted, a new picture is created automatically, in addition to the original. The end result is a brighter picture.
Nikon's In-Camera Red-Eye Fix function automatically detects and corrects red eyes in-camera. On some shots, the camera has done its trickery well, but it can also give some subjects a glazed eye affect or completely miss some red eyes.
The Coolpix 7900 features a 3x Zoom-Nikkor ED lens (focal range equivalent of a 38-114mm lens in 35mm format) and takes shots at 7.1Mp with a top resolution of 3072x2304. Images saved at this setting and at Fine quality are more than suitable for A3 enlargements. All image information is saved to either its 14MB internal memory, or to an SD card.
The 7900's body is easy to hold. For ease of use, the camera omits manual functions such as Aperture and Shutter priority.
Verdict Apart from sensor size, a few functions related to resolution, and price, the Coolpix 7900 is the same camera as the Coolpix 5900 - an excellent picture taking alternative for those not desperate for the extra couple of Mp and additional price.
