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 color 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
• Smooth, quiet autofocus operation, driven by the built-in DC motor
