Nikon led a slew of Coolpix camera launches Tuesday night with two models straddling the line between pro and amateur shooting. The P510 has one of the longest zooms ever on a non-removable lens camera and can shoot at 42X (24-1,000mm equivalent) with a purportedly more aggressive image stabilization engine. A 16.1-megapixel, backside-illuminated CMOS sensor helps combat shake along with helping in low light and improving autofocus speed.
