Like the HC1, the HC3 records up to 1080i onto standard mini-DV cassettes in HDV format, but it ups the ante with stills up to four megapixels (and even simultaneous widescreen 2.3 and 4:3 1.7 megapixel stills while shooting video), although it has a lower gross pixel count, no manual focus ring, and we've heard grumblings of a "noisier" picture.
