Nikon's $599 Coolpix P900, announced back in March, is perhaps the king of the superzoom crop. The focal length of its lens spans the range from 4.3mm to 357mm. In full-frame 35mm angle-of-view equivalent, that's a reasonably wide 24mm at one end and a monstrous 2000mm at the long end. That's a big zoom. A really big zoom.
