Versatile, 5.3-times zoom lens covering ultra-wide angles:
This zoom lens offers a zoom ratio of approximately 5.3 times to cover the ultra-wide-angle to telephoto ranges (for focal lengths equivalent to 24.5mm to 130mm in the 35mm format). In addition to the most commonly used focal lengths, it provides ultra-wide-angle coverage to produce distinctive, creative visual expressions, such as an exaggerated perspective or an extra-wide depth of field.
Exceptional imaging power to optimize the performance of super-high-resolution cameras:
Consisting of 16 optical elements in 12 groups, this lens features one ED element and three high-grade aspherical elements to minimize spherical and chromatic aberrations and improve colour rendition. In order to accommodate high-resolution image sensors in DSLRs, its MTF (Modulation Transfer Function) curve is programmed to be more acute than those of conventional models in the same class to deliver high-resolution, fine-detailed images.
HD Coating to improve image description:
This lens is treated with the high-grade, multi-layer HD Coating. Compared with conventional multi-layer coatings, this PENTAX-original coating assures higher light transmission and reduced reflections to deliver bright, high-contrast images free from flare and ghosting, even under demanding backlit conditions.
Quick-Shift Focus system:
This lens is equipped with the PENTAX-developed Quick-Shift Focus system, which allows the user to instantly switch to manual-focus operation after the subject is captured in focus by the camera’s AF system.
This lens features dependable, weather-resistant construction with eight special seals to effectively prevent intrusion of water into the lens interior. When used with a weather-resistant digital SLR camera body, it assures a durable, reliable digital imaging system that performs superbly in demanding shooting settings — even in rain or mist or in locations prone to water splashes or spray.
・SP (Super Protect) Coating (applied to the front surface of the lens) effectively repels water and grease
・Rounded diaphragm blades produce a smooth, beautiful bokeh effect; while minimizing the streaking effect from point light sources
