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.
