Olympus Zuiko 150mm f/2

Manufacturer's Description:

"Ideal for capturing nature and sporting action, the ZUIKO DIGITAL ED150mm F2.0 (35mm camera equivalent: 300mm) couples telephoto performance with high light-gathering power. The f2.0 aperture also allows the use of a shallow depth of field in the composition, to frame subjects by blurring the foreground and background. Optical precision is of course exceptional, delivering the degree of clarity and contrast expected by the best photographers."
