An exceptional addition to the Star-series, the HD Pentax-DA 11-18mm f/ 2.8 ED DC AW Lens, bundled with Hoya 82mm UV and CPL Filters, offers an ultra-wide-angle zoom lens that ensures superior optical performance across the entire zoom range. This lens is designed to deliver high-resolution, high-contrast images without any edge blur, making it an ideal choice for high-grade digital photography, even at open aperture. As the latest model in the new-generation Star series, this lens is designed to provide exceptional image quality, making it compatible with the super-high-performance digital cameras of the future.
The introduction of this lens expands the Star series' angle-of-view coverage from ultra-wide angle to telephoto. Its compact design, coupled with a large F 2.8 maximum aperture, makes it exclusively suitable for use with PENTAX APS-C-format digital SLR cameras. The lens boasts an impressive dustproof, weather-resistant construction, and a -10 Degree C cold-resistant construction, ensuring durability in harsh conditions. The Focus Clamp Mechanism allows you to lock focus at the desired focal point, enhancing the lens's operability when shooting landscapes and starry skies. This lens also features a unique design that includes a space specifically designed for wrapping a heating device to prevent dew condensation, and a metallic frame structure to effectively transmit the heat of the heating device to the lens.
These features significantly improve the lens's operability in outdoor conditions. Despite its compact dimensions, this ultra-wide-angle zoom lens provides a focal length of 11 to 18 millimeters (equivalent to 17mm to 27.5 mm in 35mm format), producing magnificent, dynamic images. Its maximum aperture is fixed at F 2.8 over the entire zoom range, delivering sharp, bright images of scenes with starry skies. With a minimum focusing distance of 0.3 meters, the lens also allows for true-to-life close-up images by emphasizing the depth of field with an effectively defocused background. The 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.
This effectively minimizes flare and ghost images even in demanding lighting conditions such as backlighting. Designed as an AW (All Weather) model, this zoom lens features a dustproof, weather-resistant construction to prevent the intrusion of water and dust particles into the lens interior. When paired with a PENTAX weather-resistant digital SLR camera body, it assures a highly durable, reliable digital imaging system that performs superbly in demanding shooting settings. This lens assures solid, trouble-free operation even at freezing temperatures, making it an ideal choice for photography in cold locations.
