Nikon Coolpix P510 Digital Camera Review

Noise Reduction

Without considering the competition, the P510 earned a strong noise score in our test. At the default noise-reduction setting, the noise-to-signal ratio didn't cross 1 percent until ISO 400, and maxed out at just 1.44 percent at ISO 3200, the top native ISO setting. That's very good for a point-and-shoot. More on how we test noise.

ISO Options

The native ISO range is 100-3200, selectable in full stops, which is typical for a superzoom these days. There's also an extended setting, Hi 1, which boosts the sensitivity to ISO 6400 at full-res. Although these are still 16-megapixel shots, we didn't consider this extended setting in our noise tests, because Nikon wisely leaves it as a last-resort setting.

Auto ISO selection is available, as are automatic caps at ISO 400 and ISO 800.
