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. The versatile zoom lens comes in handy for a wide variety of scenes and subjects, including sweeping landscapes and cramped rooms.


Exceptional imaging power to optimize the performance of super-high-resolution cameras

Consisting of 16 optical elements in 12 groups, the lens features one ED (Extra-low Dispersion) element and three high-grade aspherical elements to minimize spherical and chromatic aberrations and suppress color bleeding. In order to accommodate a super-high-pixel image sensor installed in an SLR camera body, its MTF (Modulation Transfer Function) curve is programmed to be higher 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 transmittance and less reflection to deliver bright, high-contrast images free of flare and ghost images, even under demanding lighting conditions such as backlight.
