Compact, lightweight telephoto zoom lens with outstanding portability
Despite its compact, lightweight design weighing approximately 819 grams, this zoom lens covers the image circle of 35mm full-frame digital SLRs, and provides a focal length range of 70mm to 210mm to facilitate handheld outdoor photography. When mounted on an APS-C-format camera, its focal length range is extended to the equivalent of 107mm to 322mm in the 35mm format. Coupled with its compact, lightweight body, it can be easily integrated in any APS-C-format camera system. In its 20-element, 14-group optics, it incorporates three ED (Extra-low Dispersion) glass elements and two anomalous dispersion glass elements to deliver high-contrast, high-resolution images with edge-to-edge sharpness, while effectively compensating for distortion and chromatic and coma aberrations. The lens which allows the photographer to enjoy active field photography in a wide range of outdoor applications, including scenic photography, townscape shooting and wildlife photography where its outstanding portability really comes in handy.

Technologies supporting exceptional imaging performance
Lens constructionThe lens construction, with a total of 20 elements in 14 groups, includes three ED (extra-low dispersion) glass elements and two anomalous dispersion glass elements. This reduces distortion, coma and chromatic aberration are compensated for and the conditions for high-contrast images with high resolution and sharpness all the way to the edge of the image. Thanks to internal focusing, the length of the lens barrel remains constant, whichThis makes handling much easier in many shooting situations. |

HD Coating to enhance imaging power
This lens features PENTAX’s latest HD Coating.* Compared to conventional multi-layer coatings, this high-grade, multi-layer coating not only improves light transmittance but also reduces average reflectance in the visible light range by more than 50 percent, minimizing the adverse effects of flare and ghost images even in demanding lighting conditions such as backlighting.
* HD is an abbreviation of High Definition.
Weather-resistant construction, with perfect for outdoor photographyThis zoom lens features a weather-resistant construction to prevent the intrusion of water into the lens barrel. When mounted on a PENTAX 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 at locations prone to water splashes or spray. |

* This lens is compatible with the K-3 Mark III, K-3II, K-3, K-5 II, K-5 II s, K-30, K-01, K-5, K-r, K-7, K-x, K-m, K20D, K200D, K100D Super and K10D camera bodies (with Ver. 1.30 or later firmware installed).
When mounted on other camera bodies, the focus mode is automatically switched to manual.

MTF chart information
MTF (Modulation Transfer Function) is a kind of index used to evaluate lens performance, which represents the extent of subject contrast reproduction as spatial frequency.
The MTF chart here shows the contrast on the vertical axis, and distance from the center of the image on the horizontal axis. For the spatial frequency, 10 lines/mm shows a low frequency, and 30 lines/mm shows a high frequency, resulting in the MTF graph. On the graph, the solid line represents the S direction (sagittal direction and radiation direction) MTF, and the broken line represents the M direction (meridional direction and concentric circular direction) MTF.
In general, a low-frequency MTF is proof of a clear, high-contrast lens, and a high-frequency MTF is proof of a sharp lens with high resolving power.

Nine-blade circular diaphragm for beautiful light beams and bokeh effect
This lens incorporates a Round-shaped, nine-blade diaphragm to produce a natural, beautiful bokeh (defocus) effect while minimizing the streaking effect of point light sources -
Quick-Shift Focus System
After focusing using the autofocus, the focus ring can be turned to allow immediate focus adjustment using the manual focus.
This feature enables smooth operability by eliminating the need for an AF/MF switching operation. This is useful during closeup photography, for instance, when you want to shoot while making fine adjustments to the focus

SP (Super Protect) Coating
SP coating is a PENTAX-original special coating that provides superior performance in repelling water and oils. It is used on the front surface of the first high-performance lens for effective protection of the lens surface. This coating not only prevents adhesion of dust, water drops, oils, and other substances, but it also makes it easy to wipe off objects that adhere to the lens.
Comparison of wipe-off (oil-based ink)
A lens surface treated with SP Coating can be wiped clean more easily and completely, even after the ink has dried.
