Record-breaking specs don’t always produce a well-rounded camera, however. So was this camera conceived through Nikon R&D engineering excellence, or a demand from the marketing department to produce an enormous zoom regardless of quality?
Two things dictate the effective zoom range of a camera: the lens and the sensor onto which it focuses light. The P900 uses a small 1/2.3in sensor, the same as is found in cheap compact cameras. That way, the lens dimensions can also be reduced. The lens actually has a focal length range of 4.3-357mm, but because it’s focusing light onto a much smaller area, it behaves like a 24-2,000mm lens on a full-frame camera.
That’s handy because it keeps the size down – on a full-frame camera, a true 2,000mm lens would be about the size of a small car. However, it also places high demands on the quality of the optics. Achieving sharp focus across the enormous 83x zoom range can’t be easy.
