Highly practical, approximately 5.3x zoom from ultra-wide angle. This approximately 5.3x zoom lens covers everything from ultra-wide angle to telephoto, with a focal length equivalent to 24.5-130mm (35mm equivalent). In addition to the focal range most frequently used in general photography, it is possible to obtain unique expressive effects such as the emphasis on perspective and deep depth of field unique to wide-angle lenses, and it can also be used for scenes such as vast landscapes and narrow indoor spaces, further expanding the scope of photography.
Superior image quality to match high-pixel cameras The lens construction of 16 elements in 12 groups uses three high-performance aspherical lenses and one extra-low dispersion (ED) glass element to suppress spherical aberration and chromatic aberration, achieving images with minimal color bleeding. In addition, to support high-pixel image sensors, the MTF is higher than that of previous lenses in the same class, enabling detailed images with increased resolution.
HD Coating for improved image quality This lens features our unique, high-performance multi-coating, HD Coating. Compared to conventional multi-coatings, it has less reflection and higher transmittance, which reduces ghosting and flare even under harsh lighting conditions such as backlight, resulting in high-contrast, clear images.
Quick-shift Focus SystemThe Quick-shift Focus System allows manual focusing without the need to switch focus after autofocus has been achieved.
Moisture-resistant ConstructionThe lens is weather-resistant with eight seals to prevent water from entering the lens interior. When combined with a PENTAX digital SLR body that also features a weather-resistant construction, it improves durability and reliability even in rainy or foggy weather, or in locations where it is exposed to splashes of water.
Other features include a dirt-resistant SP (Super Featured with a "Protect" coating. Circular aperture that suppresses streaks of light when photographing point light sources, producing a soft, circular bokeh. A quiet, smooth DC motor is used for autofocus.
