The Pentax Optio50L is quietly introduced. The Optio 50L is yet another 5 megapixel camera with a 3x zoom lens from Pentax. The main difference between this new model and the existing Optio50 is the addition of a 2.5 inch LCD screen, although the optical viewfinder has been sacrificed. The Pentax Optio50L is available from December 2005, price and official press release to follow.
