Pentax has today announced a four megapixel version of its pocket sized Optio 330. This camera is essentially identical to the 330 appart from its 4 megapixel CCD sensor (and, lets hope improved AF ability). "The Optio 430 measures just 3.6" (92mm) wide, 2.3'' (59mm) high, and 1.2" (31mm) deep and weighs only 7.2 ounces (205g). Precise imaging is achieved with the powerful 4.13 megapixel (total pixels) primary color filter CCD and a superior PENTAX 3X zoom lens (equivalent to 37.5-112.5mm in 35mm format) which provides high-resolution images and low image distortion."
