| Background |
|
| “ZUIKO DIGITAL” interchangeable lenses are specifically designed to maximize the performance potential of the image sensors in “Four-Thirds System” digital SLR cameras. Newly announced “ZUIKO DIGITAL ED 40-150mm F4.0–5.6” lens is a lightweight, ultra-compact telephoto zoom lens that offers outstanding value. |
|
| “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. |

| Main Features |
|
| 1. |
Lightweight and Ultra-Compact Design |
| |
| “ZUIKO DIGITAL ED 40-150mm F4.0-5.6” uses ED (Extra-low Dispersion) and high-performance glass elements and an optimized zoom range to ensure outstanding performance and portability. Packing the equivalent of 300mm telephoto power in a barrel only 72mm long, and weighing just 220g, it makes it easy to enjoy true telephoto shooting in the field. The lens’s 3.8x zoom covers a wide range of focal lengths, and offers performance equivalent to 80-300mm on a 35mm camera. |

| 2. |
Excellent Close-Focusing Capability |
| |
An inner focusing system assures that lens length remains constant, and provides close focusing from 90cm at any focal length. |
|
|
| Other Features |
|
| ･ |
Superior 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. |
|
|
| ･ |
Filter Support |
| |
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. |
