Canon's budget zoom model has upgraded from a CCD to a 1/2.3" CMOS sensor meaning users of the new SX510 should see significant improvement over the older SX500 in low light scenarios. Besides the improved sensor, the SX510 also includes wi-fi, a rarity for a $250 advanced camera. Video quality was also improved from 720 to 1080p. Needless to say, the SX510 is definitely worth the few extra bucks to pick up this year's model. Canon's point-and-shoot models usually offer exceptional quality for the price and we don't expect any different for the SX510. This model also features optical image stabilization, a nice 30x zoom, and up to 10 fps continuous shooting. Nikon's P520 will get you a longer zoom and built-in GPS, but comes at a much higher price. The SX510 has exceptional value for the $250 price tag.
