The timing of the new Olympus Pen E-P1 isn't a coincidence. It's 50 years since Olympus launched the original Pen, a revolutionary 'half-frame' camera that was eventually developed into an SLR with a 'porro-finder' rather than a conventional pentaprism, a design which resurfaced in the Olympus E-300 and E-330.
