This zoom lens provides focal lengths between 84.5mm and 460mm (in the 35mm format)* to cover medium- to super-telephoto ranges. Thanks to its upgraded AF performance, it assures quiet, high-speed AF operation in still-image shooting, as well as smooth AF tracking operation during movie recording to minimize operation noise caused by focus and aperture shifts. Its newly designed, high-quality optics provide a minimum focusing distance of 0.95 meters, expanding the range of photographic applications. With the adoption of a retractable structure, it measures a mere 89 millimeters in length, making it easy to carry around. Coupled with its weather-resistant construction, this zoom lens assures outstanding reliability and durability even in demanding shooting conditions.

Quiet AF operation and electromagnetic diaphragm control, perfect for movie recording
This is the first K-mount lens to feature an electromagnetic diaphragm control system.* When mounted on the new PENTAX K-70 digital SLR camera body, it assures smooth, high-precision aperture control during movie recording. Thanks to this state-of-the-art system, it shifts the aperture setting automatically and smoothly, even when the brightness level of the subject changes drastically in movie shooting. Coupled with the PLM mechanism, it also assures smooth AF tracking operation and exposure control, while minimizing the intrusion of focus- and aperture-shift noises during movie-recording operation. As the result, it produces more natural, true-to-life movies in locations such as a theater stage or a sunlight-streaked forest where the brightness level fluctuates considerably, and for such active subjects as athletes and animals.
This lens features a KAF4 lens mount compatible with an electromagnetic diaphragm control system. In order to use this lens, the camera’s firmware must be upgraded to the latest version (except for the PENTAX K-70). If this lens is mounted on a camera without proper firmware upgrade, its diaphragm control mechanism becomes inactive, making it impossible to obtain correct exposure.
Cameras compatible with this system: PENTAX K-70, K-1, K-3 II, K-S2 and K-S1
High-quality images, with a minimum focusing distance of 0.95 meters
With focal lengths from 84.5mm to 460mm (in the 35mm format), this telephoto zoom lens provides approximately 5.5-times zoom coverage from medium- to super-telephoto ranges. Its 14-element, 11-group optics include an ED (Extra-low Dispersion) optical element to effectively minimize spherical and chromatic aberrations, while delivering high-resolution, fine-detailed images with rich contrast from the image’s center to its edges and minimal color bleeding at any focal length setting. In addition to the short minimal focusing distance of 0.95 meters, made possible by the rear-focus system, the lens barrel has also been designed to be free of extension during AF operation, making it ideal for a wide variety of applications, such as outdoor, sports and landscape shooting.
The lens features a dependable weather-resistant construction with 11 sealing parts to effectively prevent the intrusion of water into the lens interior. When paired with a weather-resistant PENTAX digital SLR camera body, it creates a durable, dependable digital imaging system that performs superbly in demanding shooting settings — even in rain or mist, or in locations prone to water splashing or spray.
