Steve's Digicams reviews the Pentax Optio MX4 and writes - 'When we first received the MX4 we were hoping Pentax had corrected some of the weaknesses found on its predecessor. While it's capable of producing good quality 4-megapixel images, its promises are largely unfulfilled. Pentax claims it is "Two Great Cameras in One" (still/movie), however its movie results were disappointing. And while its versatile 38-380mm optical zoom lens invites action and wildlife photography, its leisurely autofocus and shooting performance will dampen your fun. However, we did find that the MX4 was at its best doing interior flash photography, especially with the L-WC17 Wide Conversion lens attached. '
