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.
*When mounted on a PENTAX APS-C-format digital SLR camera.
- Quick-Shift Focus System allows the user to instantly switch to manual-focus operation, even when the camera's AF system is in operation.
- SP (Super Protect) Coating applied to the front surface of the lens to effectively repel water and grease.
- Rounded diaphragm with nine blades to produce a smooth, beautiful bokeh (defocus) effect, while minimizing the streaking effect of point light sources.
This lens features a KAF4 lens mount compatible with an electromagnetic diaphragm control system. Cameras compatible with this system are KP, K-70, K-1, K-3 II, K-3, K-S2, K-S1 and K-50. For K-1, K-3 II, K-3, K-S2, K-S1 and K-50, the camera's firmware must be upgraded to the latest version. 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.
