Pentax HD DA* 11-18mm /2.8 ED DC AW (21230)

 With the introduction of this lens, the high-quality, high-performance Star series now provides a wide angle-of-view coverage —from ultra-wide angle to telephoto — with its compact models featuring a large F2.8 maximum aperture, which are exclusively designed for use with PENTAX APS-C-format digital SLR cameras.

 In addition to an outstanding dustproof, weather-resistant construction, and -10°C cold-resistant construction, the lens provides a Focus Clamp Mechanism to lock focus at the desired focal point. It also provides useful features to improve performance and dependability in harsh outdoor conditions: a space specifically designed for wrapping a heating device to prevent dew condensation, and a metallic frame structure to more effectively transmit the heat of the heating device to the lens. These devices greatly improve the lens’s operability when shooting landscapes and starry skies.
