HD Pentax-DA 11-18mm f/2.8 ED DC AW Lens Summary

The new-generation Star series HD Pentax-DA 11-18mm F/2.8 ED DC AW Lens is an ultra wide angle zoom for crop sensor APS-C format . The lens delivers exceptional optical performance with a large f/2.8 aperture throughout the entire zoom range. This allows you to shoot at wide apertures in low light situations as well as separating subjects from their background with a shallow depth of field. With an equivalent focal range of 17mm to 27.5mm in 35mm format this lens excels at subjects including landscapes, architecture, astro photography and interiors amongst others.

As a Star series model, this joins other high end  designed to be future-proof with existing and future high resolution sensors. It includes high-end features designed to maximise image quality including HD and Super Protect coatings, a DC focus motor and nine-bladed aperture diaphragm.

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 , 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.
