Just Posted: Although it retains its predecessor's styling, the Olympus PEN E-P3 shares very little else with its forebears. There's still a 12MP Four Thirds-sized sensor at its heart, but its autofocus, rear screen and movie capabilities have all been radically overhauled. Crucially, Olympus has also managed to squeeze a flash into the body. Now sitting at the top of a three-model range, the E-P3 is clearly positioned as a camera for enthusiasts. So, do its third-generation refinements and promises of world-beating AF performance make the E-P3 into the camera that the PEN series always promised to be?
