With its wide zoom coverage of approximately 5.5 times, the lens offers focal-length coverage from 84.5 medium telephoto to 460mm super telephoto (in the 35mm format), making it ideal for use with a wide variety of subjects and applications including portraits, sports and landscapes. It features weather-resistant construction to prevent the intrusion of water and moisture into the lens barrel. When mounted on a PENTAX weather-resistant digital SLR camera body, the user is assured of greater durability and reliability when shooting in rain or mist, as well as at locations subject to a spray or splash. It incorporates two ED (Extra-low Dispersion) glass elements in its optics to effectively compensate for chromatic aberrations over the entire zoom range and deliver well-defined, true-to-life images. Complete with the PENTAX HD coating, enjoy higher light transmittance and lower reflectance than conventional multi-layer coatings.
