HD Pentax-DA 11-18mm F/2.8 ED DC AW Lens In More Detail
Large f/2.8 maximum aperture
This ultra-wide-angle zoom lens provides a focal length of 11-18 millimetres (equivalent to 17mm to 27.5mm in 35mm format) produce magnificent, dynamic images despite its small size. With its maximum constant F2.8 aperture over the entire zoom range, the lens delivers sharp, bright astro, aurora and star images. A minimum focusing distance of just 0.3 meters allows the photographer to capture true-to-life close-up images by emphasising the depth of field with an effectively defocused background.
Enhance imaging power with HD Coating
This lens features high-grade, multi-layer HD Coating which reduces the average reflectance in the visible ray spectrum to less than 50% of conventional multi-layer coatings. It effectively minimises flare and ghosting in images even during demanding lighting conditions such as backlighting.
Optimised for landscapes and star photography
The unique Focus Clamp Mechanism allows the photographer to lock the lens’s focal point, even when the focus ring is rotated. This improves the lens’s operability in photographing such subjects as landscapes and star-lit scenes, which demand high-precision focusing during extended exposures. It also has special features for improved operability and versatility in outdoor shooting, such as a space for wrapping heating wires around the lens barrel to prevent dew condensation, without affecting focus-ring operation; and a metallic frame structure to more effectively transmit the heat of the heating device to the lens.
Dust-proof, weather-resistant and -10 ℃ cold-resistant construction
Developed as an All Weather (AW) model, this 11-18mm zoom lens features a dust-proof, weather-resistant construction to prevent water and dust particle intrusion into the lens interior. By pairing it with a weather-resistant digital SLR camera body like the Pentax K-3 Mark III Camera (Black), this assures a highly durable, reliable digital imaging system that performs superbly in demanding shooting settings — even in rain or mist, or at locations prone to water splashes. Anticipating use in cold locations, this lens assures solid, trouble-free operation even at freezing temperatures.
