 Olympus Zuiko Digital ED 50-200mm f2.8-3.5 SWD lens : Olympus released, next to its new E-3 DSLR camera, three new Zuiko Digital lenses and a tele converter. Among them is the Zuiko Digital ED 50-200mm f2.8-3.5 SWD lens. This 100% digital-specific optic incorporates Olympus’ new Supersonic Wave Drive technology, to provide ultra-fast, whisper-quiet auto focus (AF) speed, and offer several impressive distinctions. Two compact SWD devices power auto focus at a very high speed by exciting unique elliptical oscillations. The compact 5.3mm x 4.3mm optical encoder detects and controls the lens drive position using direct rotation detection without reduction gear. This enables it to achieve a level of precision that’s accurate to 5 microns.

John Knaur, senior marketing manager, Digital SLR, Olympus Imaging America Inc stated: "With the new SWD lenses, we’ve got outstanding glass to match the high quality performance of our flagship E-3 digital SLR. In testing, the 50-200mm SWD focused twice as fast as the previous Zuiko Digital lens with that focal length, which makes it an ideal lens for sports and action photography. This lens, in combination with the other introductions will fulfill many photographer’s focal length needs."
Olympus Zuiko super-telescopic zoom lens
The Zuiko Digital ED 50-200mm f2.8-3.5 SWD is a high-performance super-telescopic zoom lens that features, for the first time, the SWD (Supersonic Wave Drive) Auto focus system and covers a zoom range equivalent to 100mm to 400mm of a 35mm camera lens. ED lens elements are being used extensively to correct color blurring which can occur when telescopic lenses are extended to their maximum focal length. The digital-dedicated design ensures high-definition performance with crisp and crystal clear images from edge to edge. In addition, close-up shooting is also superb, with a minimum shooting distance of just 1.2 meters throughout the zoom range.
Olympus Zuiko SWD Auto focus system
Auto focus is powered by Olympus’ newly designed SWD technology, which enables the lens to achieve an AF speed which is about 2x faster than the previous ED 50-200mm f2.8-3.5 model. As an ideal partner for the Olympus E-3 DSLR, this Zuiko lens maximizes the camera’s high-speed auto focus capability. The superior tracking capability makes the Zuiko Digital 50-200mm lens an ideal companion for sports photography and outdoor shooting applications.
Olympus Zuiko Digital ED f2.8-3.5 SWD
When using the Zuiko ED 50-200mm SWD lens in combination with the new Olympus E-3, which offers improved AF computation and lens-body communication rates, the SWD motors provide fast focusing speed of approximately 170 ms (0.17 seconds). The new Zuiko Digital SWD lens will be manufactured at the Olympus Tatsuno Plant in Japan, which is equipped with state-of-the-art production technology in the field of optical equipment. The Zuiko Digital ED 50-200mm f2.8-3.5 SWD will be available in December 2007, at an estimated retail price of $1,199.99.
