The full frame HD PENTAX-D FA 15-30mm f/2.8 zoom lens covers a focal length span of 15mm ultra-wide to a 30mm wide-angle. With its exaggerated perspective, the lens is capable of capturing vivid images with dynamic views perfect for use with landscape photography. It was built with PENTAX-developed HD Coating to guarantee fine details as well as sufficient lighting power even at the edges of the image and reduces chromatic aberration and distortion. The optical construction consists of 18-element, 13-group optics with three ED (Extra-low Dispersion) glass optical elements and three aspherical optical elements offering high-resolution images rich in contrast while effectively minimising chromatic aberration, distortion and coma. This lens comes along with the full frame K-1 DSLR providing a large f/2.8 maximum aperture perfect for nigh skies and other night photography. The built-in SDM (Supersonic Direct-drive Motor) however, provides high-speed yet whisper-quiet autofocus operation. Other features include weather-resistant construction in addition to the SP (Super Protect) Coating applied to the front surface to effectively avoid water intrusion, rounded diaphragm with nine blades for a smooth and beautiful bokeh. It is compatible with Full Frame and APS-C DSLR Cameras.
Product Features in Detail
Exceptional imaging power
When mounted on the PENTAX K-1 35mm full-frame digital SLR camera body, the lens provides an ultra-wide-angle focal-length coverage from 15mm to 30mm. Its exaggerated perspective helps the photographer produce spectacular landscape photographs. With a 30mm focal length at the telephoto end, the lens is also well-suited to portrait and street photography.
State-of-the-art optical design
The zoom lens incorporates three ED (Extra-low Dispersion) glass optical elements and three aspherical optical elements in its 18-element, 13-group optics to deliver high-resolution images rich in contrast even at the edges of the image field, while effectively minimizing chromatic aberration, distortion and coma.
Large-aperture zoom lens, with a maximum aperture of f/2.8
Since this zoom lens provides a maximum aperture of f/2.8 over its entire zoom range, it is versatile enough to be used for many different subjects and scenes, ranging from sweeping landscapes to nightscapes and starry skies. Despite its ultra-wide-angle perspective, it can capture the subject with an excellent bokeh (defocus) effect on the background. Even in macro photography from its minimum focusing distance of 28 centimeters, it can capture subjects with a well-defined sense of depth.
Built-in SDM (Supersonic Direct-drive Motor)
The incorporation of a new-generation SDM (Supersonic Direct-drive Motor) assures that this zoom lens provides quiet, high-speed autofocus operation, letting the photographer react swiftly to all types of subjects.
Weather-resistant construction
Special seals applied throughout the lens body provide this zoom lens with dependable weather-resistant construction, effectively preventing the intrusion of water into the lens interior. By pairing it with a weather-resistant PENTAX digital SLR camera body, the photographer has a durable, dependable digital imaging system that performs superbly under demanding shooting conditions — even in the rain or mist, or at locations prone to water splashes or spray.
HD Coating to improve image description
The lens is treated with high-grade, multi-layer HD (high-definition) coating. Compared with conventional multi-layer coatings, this PENTAX-original coating assures higher light transmittance and less reflection to deliver bright, high-contrast images free of flare and ghost images, even under demanding lighting conditions such as backlight.
Other features
Quick-Shift Focus System for instant switching from autofocus to manual-focus operation, by holding the shutter-release button halfway down and turning the focus ring after the subject is captured in focus by the camera's AF system.
Rounded diaphragm with nine blades produces a smooth, beautiful bokeh (defocus) effect, while minimizing the streaking effect of point light sources.
SP (Super Protect) coating applied to the front surface of the lens to effectively repel water and grease.
