The PENTAX-DA HD 55-300mm f/4.5-6.3 ED PLM WR RE Lens is an 84.5-460mm (35mm equivalent) telephoto zoom designed for APS-C-format K-mount DSLRs, that's Versatile and long reaching. Ranging from portrait-length thru super telephoto, this lens makes use of extra-low dispersion glass in its optical design as a way to reduce color fringing and chromatic aberrations all through the far-reaching zoom range. An HD coating has also been added to lens elements to diminish flare and ghosting for enhanced contrast and color fidelity when shooting in strong lighting conditions. Additionally, an SP (Super Protect) coating has been added to the front and rear exposed surfaces of the lens, too, to protect against fingerprints, smudging, and cleaning marks.
Complementing the optical design is a quick action PLM (Pulse Motor), which delivers smooth, quiet, and precise autofocus operation to create an advantage for both still image shooting and video capture. A compact and lightweight form factor, together with a retractable design, also adds to intuitive handling and use while on the go, plus a weather-resistant construction is a benefit shooting in trying weather conditions.
