Main features of "HD PENTAX-D FA 15-30mmF2.8ED SDM WR":1. High-resolution imaging performanceWhen mounted on a 35mm full-frame digital single-lens reflex camera "PENTAX K-1," it provides an ultra-wide-angle view with a focal length of 15~30mm, allowing you to create more magnificent landscape photographs with an overwhelming perspective. Furthermore, with a telephoto end focal length of 30mm, it is suitable for snapshot photography and other uses.
2. Latest optical designAdopts a lens configuration of 13 groups and 18 elements, including 3 special low dispersion (ED) glass elements and 3 aspherical lenses, thoroughly correcting chromatic aberration, distortion aberration, and coma aberration, achieving high contrast and high-resolution imaging even at the periphery.
3. F2.8 large aperture lensWith a constant aperture of F2.8 throughout the zoom range, it is bright and ideal for landscape, night scenery, and star photography, greatly expanding your shooting possibilities. Despite being ultra-wide-angle, it allows for background bokeh effects, with a minimum focusing distance of 28cm, enabling three-dimensionality of the subject in macro photography.
4. Built-in ultrasonic motor (SDM)Equipped with a new type of ultrasonic motor (SDM) inside the lens, enabling high-speed and quiet autofocus, providing comfortable operation.
5. Water-resistant constructionFeatures a sealing throughout the lens to prevent water droplets from entering, adopting a water-resistant structure. When combined with our digital single-lens reflex camera bodies equipped with water resistance, it enhances reliability in rainy, foggy, or water-splash-prone environments.
6. Enhanced imaging performance with ""HD coating""Uses the latest high-performance multi-coating ""HD coating"". Compared to conventional multi-coatings, it has less reflection and higher transmittance, reducing ghosting and flare under challenging lighting conditions such as backlighting, and achieving high contrast and clear imaging.
Note 2: "HD" stands for High Definition.
7. Other features① Equipped with ""Quick-Shift Focus System"" that allows manual focus adjustment at any time without switching modes, simply by half-pressing the shutter button in autofocus mode.② Uses a 9-blade circular aperture to suppress starburst effects from point light sources and produce soft, round bokeh.③ The front of the lens is coated with SP (Super Protect) coating, which is resistant to dirt.
【In-body image stabilization SR/SRII】 Pentax digital single-lens reflex cameras in the K series are equipped with in-body image stabilization that extends the limits of handheld shooting.【High-resolution imaging performance】 Achieves overwhelming perspective and high-resolution imaging characteristic of ultra-wide-angle lenses, enabling especially grand and dynamic expressions in landscape photography.【Latest optical design】 Uses 3 special low dispersion (ED) glass elements and 3 aspherical lenses, thoroughly correcting chromatic aberration, distortion, and coma aberration, and providing high contrast and high-resolution imaging even at the edges.【Large aperture F2.8】 The maximum aperture value is F2.8 throughout the zoom range, making it powerful not only for landscape photography but also for starry sky photography.【Built-in ultrasonic motor SDM】 Enables high-speed, quiet autofocus for comfortable operation.
