The P100 is Nikon's top-of-the-line megazoom camera, extending out to a questionably useful 26x. Along with that lens it has many features and capabilities, thanks, in part, to its backside-illuminated 10-megapixel CMOS sensor.
The P100 offers high-speed continuous shooting of stills at up to 120 frames per second and video at up to 240fps. It has a regular movie mode, too, that goes up to 1080p HD quality. There are also shooting modes for creating high-dynamic-range photos and taking handheld low-light shots.
Controls are easy to use and menu systems are clean and simple to navigate, making experimentation with its many, many shooting modes uncomplicated and fun.
The thing is, though, for all the P100's features and capabilities, the photo quality just isn't that good. So if you're expecting digital SLR-quality photos simply because this is a high-end camera with a long lens and an SLR-style design, you're going to be disappointed. If you can accept that the cost gets you the features and not superb photos, you'll probably like this camera quite a bit.
