Pentax HD DA 55-300mm f/4.5-6.3 ED PLM RE Lens
Versatile and long reaching the HD PENTAX-DA 55-300mm f/4.5-6.3 ED PLM WR RE Lens from Pentax is an 84.5-460mm equivalent telephoto zoom designed for APS-C-format K-mount DSLRs. Ranging from portrait-length to super telephoto, this lens employs extra-low dispersion glass in its optical design in order to reduce color fringing and chromatic aberrations throughout the expansive zoom range. An HD coating has also been applied to lens elements to minimize flare and ghosting for increased contrast and color fidelity when working in strong lighting conditions. Furthermore, an SP (Super Protect) coating has been applied to the front and rear surfaces of the lens, too, to guard against fingerprints, smudging, and cleaning marks.
