According to us (GeekTech) out of all the Nikons announced today, the P310 and P510 are likely to be the most popular. Though P310’s 4.2x (24-100mm) focal length may not deliver the awesome zoom of the P510, and it can’t do anyting like the P7100, but it does have some serious optical features.
P310 has improved image stabilization, which Nikon says will let you take blur-free handheld shots at four stops below and also a “market leading” f/1.8 maximum aperture, which further aid low-light shooting as well shallow depth-of-field shots. This camera is a lot smaller than either the P510 or the P7100 and it feels great in the hand: not quite pocketable, perhaps, but certainly portable, discreet and sturdy.
The Coolpix P510 “breaks the zoom barrier” with a 42x 24-1000mm optically stabilized lens. It features a 16.1 megapixel BSI (backside illuminated) CMOS sensor, a 921k-dot 3-inch vari-angle LCD, can shoot 1080p HD video with stereo sound and supports ISO 100-3200 shooting with Hi1 (ISO 6400) and Hi2 (ISO 12800, monochrome) options. GPS functionality is also included, with support for tracking and photo geotagging.
Whereas P310 which offers the same 16.1 megapixel BSI CMOS sensor, a 921k-pixel 3-inch LCD, a native sensitivity range of ISO 100-3200 (Hi1 of ISO 6400) and a 4.2x 24-100mm f/1.8 (maximum) optically stabilized zoom lens. As Nikon’s high-end pocketable model, the P310 offers advanced exposure modes, including program, shutter- and aperture-priority, along with a full manual mode. There’s also 1080/30p video capture with stereo sound and in-camera editing. Both cameras will be available in February, with the Coolpix P510 shipping in black and red for $430 and the black-only P310 running you $330.
