New HD (High Definition) Coating for exceptional image rendition
Treated with HD coating, a PENTAX-exclusive multi-layer lens coating, enjoy 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.

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 PENTAX-original Quick-Shift Focus System allows instant switching from autofocus to manual focus operation.
The PENTAX-original SP (Super Protect) coating repels dust, water and grease to keep your lens clean and your image quality at its peak.
