The Pentax SMCP-DA 55-300mm f/4-5.8 ED Lens offers an extreme telephoto zoom range, and is perfect for those moderate to long telephoto shots. Designed specifically for digital SLR cameras, this lens provides an angle-of-view equivalent to an 82.5-450mm lens in the 35mm format.
The SMCP-DA 55-300mm f/4-5.8 ED's elements have been treated with Pentax's acclaimed Super-Multi-Coating for maximum light transmission, sharp definition, and high contrast, while minimizing flare and ghost imaging. In addition, SP coating is used on the exterior element to protect the lens against water and grease. ED elements compensate for chromatic aberration.
