The Olympus 12-60mm f/2.8-4 ED SWD Zuiko Zoom Lens for Olympus Digital Cameras is designed to meet the needs of the professional photographer, Zuiko Digital lenses were born of an uncompromising commitment to performance. The lenses feature high resolving power, to get the most out of the imaging element. Zuiko Digital lenses allow light to strike the image sensor at a near-perpendicular angle, minimizing degradation and light loss. This large, award-winning family of lenses is perfectly matched to work exclusively with digital cameras so every pixel is properly exposed.
In combination with the E-3 Digital SLR, this lens delivers the fastest autofocus speed in the world.* It covers a zoom range equivalent to 24mm to 120mm on a 35mm camera lens. This lens also boasts impressive close-up shooting capability, allowing users to shoot from as close as 25cm throughout the zoom range. Autofocus is powered by Olympus' breakthrough SWD. Designed to be the world's fastest AF system, this extraordinary autofocus drive provides both high speed and high precision while operating with extremely low noise.
The autofocus speed of the ZUIKO DIGITAL 12-60mm (24-120mm) f2.8-4.0 SWD lens combined with the E-3 was measured in-house testing by Olympus and is based on similar available lenses for digital SLR cameras as of October 17, 2007.
