  • Equivalent to 84.5-460mm in 35mm film format
  • High Definition Coating
  • Extra low-dispersion ED lens elements


High-grade HD coating* for exceptional image rendition

The lens is treated with HD coating,* a Pentax-exclusive multi-layer lens coating that assures higher light transmittance and lower reflectance than conventional multi-layer coatings. This means it produces sharp, clear images free of flare and ghost images, even under such adverse lighting conditions as backlight.

* HD stands for High Definition.

Dependable weather-resistant construction

The lens features weather-resistant construction to prevent the intrusion of water and moisture into the lens barrel. When the lens is 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.

Quick-Shift Focus System

The lens features the Pentax-developed Quick-Shift Focus System, which allows the user to instantly switch to manual-focus operation after the subject is captured in focus by the camera’s AF system.
