Olympus Zuiko Digital ED 40-150mm lens
Olympus Zuiko Digital ED 40-150mm lens : Olympus Imaging Corporation announces the introduction of the Olympus Zuiko Digital ED 40–150mm F4.0–5.6, a new Designed-for-Digital telephoto zoom lens for FourThirds System DSLR cameras. The new lens is scheduled to go on sale in Japan on November 23, 2006. Zuiko Digital interchangeable lenses are specifically designed to maximize the performance potential of the image sensors in FourThirds System digital SLR cameras. The newly announced Olympus Digital ED 40-150mm is a lightweight, ultra-compact telephoto zoom lens that offers outstanding value. A non-rotating mount ensures that filters do not rotate when the lens is focused, making it much easier to shoot when using polarizing filters.|

“Zuiko Digital ED 40-150mm F4.0–5.6” is the lightest (220g) and smallest lens in its class*, and boasts the shortest minimum shooting distance (0.9m). Its wide zoom range is equivalent to 80–300mm on a 35mm camera, and its “Four-Thirds System” design assures outstanding portability that makes interchangeable lens photography easier. An inner focusing system assures that lens length remains constant, and provides close focusing from 90cm at any focal length.

Zuiko Digital ED 40-150mm - Imaging characteristics
ED and high refractive index glass elements are used to minimize chromatic aberration, coma flare, and image curvature. Sharp, high-contrast imaging is achieved at the outer periphery of the lens at all focal lengths. Advanced technologies for high image quality include multi-coating to reduce ghosting and flaring in backlight, and the use of a circular iris to achieve smooth, soft, background defocusing.
