Review (Summary): "The Nikon Coolpix P310 is a modest update to its predecessor, the P300, and maintains many of the same features in almost exactly the same body design. Physically very similar to competitors like the Canon PowerShot S100, it offers PASM exposure modes and a useful-but-not-enormous zoom range (24-100) with a reasonably fast maximum aperture of F1.8-4.9. Unlike the S100 though, the P310 is a JPEG-only camera and uses a considerably smaller sensor. This might limit its appeal to enthusiast photographers, but allows a relatively low price compared to its high-end peers, making it potentially attractive to buyers who don't need the greater post-capture versatility offered by Raw but still want full manual control."
