Compact ultra-wide-angle Zoom lens for use on PENTAX cameras with APS-C sensor, ideal for shooting astrophotography and landscape photography.
The HD PENTAX-DA 11-18 mm F2.8 ED DC AW (equivalent to 17 to 27.5 mm in 35 mm full-frame format) is the latest lens in the new generation of the PENTAX star series. Lenses of this series stand for excellent high optical performance and first-class features. The Stern series is not only designed to meet the current demands of digital photography, but also to be prepared for future generations. Like all lenses in this series, the 11-18mm ultra-wide-angle Zoom lens delivers high-resolution, high-contrast images without blurring to the edges of the frame, and guarantees fabulous imaging performance even at open aperture.
With the introduction of this lens, the high-quality, high-performance Stern series now offers compact lenses with a minimum aperture of F2.8, from ultra-wide to telephoto, for PENTAX digital cameras.
As with all lenses in this series, particular emphasis has been placed on performance characteristics under adverse conditions. For example, the lens not only has seals to prevent moisture or dust from entering the lens, but is also prepared for use with a dew cap heater, which greatly improves the operability of the lens when photographing landscapes and starry skies.
Lenses with outstanding performance are marked with a star in the PENTAX system. To receive this designation, the following three basic parameters must be met:
The aim is not only to ensure that the lenses in the Stern series are ideally matched to current recording sensors, but also to design them for future recording technologies while keeping them as compatible as possible with older cameras.
To achieve high optical quality with the smallest possible dimensions, this lens consists of 16 lens elements in 11 assemblies. A total of three ED lenses and two aspherical lenses (AL) were used. One of the ED lenses is combined with AL to reduce chromatic and spherical aberrations with one glass.
Despite its compact size, the new ultra-wide-angle Zoom lens has a very large input aperture of F2.8 over the entire Zoom range. The short minimum focus distance of 30 cm allows you to create very realistic images with a great depth of field that you can emphasize in the background by blurring, with a soft bokeh through nine aperture blades.
The lens elements of this lens feature the multi-layer HD (High Definition) coating developed by PENTAX, which offers significantly higher light transmission with low reflection (about 50% less than conventional multi-layer coatings) compared to conventional coatings. This allows maximum contrast and sharpness without flare and ghosting even under difficult conditions such as backlighting.
