HD Pentax-DA 55-300mm f/4-5.8 ED WR Lens from Pentax is a portrait-length to telephoto zoom lens that provides a 35mm-equivalent focal range of 84.5-460mm. This extensive zoom range is complemented by the inclusion of two extra-low dispersion glass elements, which work to minimize chromatic aberrations and enhance overall image sharpness and clarity. A high-grade multi-layer HD coating has been applied to lens elements to help minimize flare and ghosting for enhanced contrast and, additionally, an SP Protect coating has also been applied to the front lens element to effectively protect it from dirt, oil, and finger prints.

The lens features a weather-resistant construction, which helps to prevent moisture and dust from entering the lens and affecting its performance and a highly durable metallic mount ensures a secure connection between the camera and lens. Pentax's Quick-Shift Focus System has also been incorporated into the design, which permits quick changing to manual focus control at any time, even in AF mode, for precise handling over the focal plane.
