Catching up with reviews started before PMA I've just put the finishing touches to my review of Pentax's four megapixel Optio 430. The camera (and thus my review) is based heavily on the Optio 330. Indeed, the entire body design, control system and menus are identical to the 330. What we needed to test in this review was the resolution advantage of going from the 3 megapixel to the 4 megapixel model.
