The selection of a digital camera largely depends on the type of photography you like to do. The market is flooded with different varieties of digital cameras for various purposes. If you are inclined towards wild life photography, look for a camera with Center-Weighted metering. Center weighted metering is a feature by which the light reflected by the object is measured accurately with in the digital camera. The camera is focused at the center of the object.
On the other hand if you are more interested in nature photography, a wide angle lens and memory exposure lock is a must for you. Memory exposure is responsible for the depth of a photograph. The wide angle lens brings the depth visible. Always make sure that you carry a light camera if you are mountaineering or going for an adventure trip.
