Olympus revealed the metal clad Camedia C-50 Zoom at Photokina 2002, a camera with a clean design it maintained the Olympus compact family appearance with the sliding front cover but improved the finish level thanks to its magnesium alloy body. The C-50 Zoom has a 1/1.8" (7.2 x 5.3 mm) five megapixel CCD sensor and three times optical zoom lens. The C-50 Zoom is also the first Olympus digital camera to be powered by a dedicated Lithium-Ion rechargeable battery (capacity 1090 mAh at 3.7V). The C-50 Zoom is aimed at the advanced amateur, it has some surprisingly prosumer type features (such as aperture and shutter priority) but seems to fall short of carrying the prosumer label thanks to its lack of manual white balance, manual focus and other advanced features (which is a pity).
