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.
The PENTAX-original SP (Super Protect) coating repels dust, water and grease to keep your lens clean and your image quality at its peak.
The focal length is equivalent to 82.5mm to 450mm in the 35mm format.
