A major factor in the D300’s stellar image quality is the new Sony-made 12.3MP (effective) CMOS sensor that captures RAW data with up to 14 bits of color per red, green, and blue channels. Most other DSLRs in this class only provide 12 bits per channel. This gives the D300 an advantage in reproducing fine color gradations, shadow details, and wider dynamic range. But it also increases the file size of images recorded in the 14-bit mode (selectable over normal 12-bit RAW).

This camera - Coolpix P5100, like all the compacts that boast absurdly high pixel counts, is prone to image noise above ISO200. Below that point the images are clean enough, particularly if the end display medium is a 10 by 15 cm print. With Noise Reduction turned on in the menu there is some loss of fine detail at ISO400 and above. However, if your expectations are not too high, the output at a stratospheric ISO3200 is acceptable, with a bit of post-camera clean-up in noise removal software. The sad fact is that if this camera had a 7 megapixel sensor it would be a world-beater.

We really enjoyed using it, and as the only competition, the Canon G9, is also over-pixelled these are as good as it gets in compact cameras.

The Coolpix P5100 is designed to be both a point and shoot and a camera that can satisfy the needs of a more assiduous photographer thanks to the inclusion of more advanced modes and a fully manual mode. And once printed, or reduced in size so as to be seen whole on a monitor, or on high definition television or through a projection system, the images from the Coolpix 5100 should please most people.
