  • Standard Zoom Lens
  • Offering approx. 4.1X Zoom Ratio
  • For Pentax Digital SLR Cameras
  • Filter Diameter - 67mm
  • Approximately 4.1-times zoom ratio covering from wide-angle to moderate-telephoto ranges
  • Focal length range from 26mm wide angle to 107mm telephoto in the 35mm format
  • Offers the most frequently used focal lengths in day-to-day photography, making it ideal for a host of casual applications, including scenery, snapshot and portraiture
  • Extra-smooth, extra-quiet SDM autofocus system
  • SDM system driven by a built-in supersonic motor, this zoom lens offers exceptionally smooth, quiet autofocusing operation
  • On an SDM-compatible Pentax digital SLR camera body,* the focus mode is automatically switched to SDM-assisted autofocusing
  • Because this zoom lens has been developed exclusively for SDM-assisted autofocusing, it is designed compact and maneuverable despite the incorporation of the built-in supersonic motor (* This lens is compatible with the K20D, K200D, K100D Super and K10D (with Ver. 1.30 or later firmware installed) camera bodies)
  • When mounted on other camera bodies, the focus mode is automatically switched to
  • Exceptional Image
  • Incorporating two hybrid aspherical (AL) optical elements in its optics, this zoom lens assures exceptional image quality, while effectively compensating various aberrations
  • Maximum aperture of F4 over the entire zoom range
  • Lets the photographer use higher shutter speeds to minimize annoying camera shake--especially in telephoto applications--or reduce the depth of field to intentionally throw the background out of focus
  • Digital SLR-exclusive Optical Design
  • From lens coating and curvature to the positioning of optical elements, the optics has been meticulously designed to optimize the lens' digital imaging characteristics
  • Image circle is perfectly proportioned to the camera's image-sensor size
  • Other Features
  • Minimum focusing distance of 0.28 metres over the entire zoom range
  • Inner-Focus (IF) system to eliminate lens extension and retraction during focusing operation
  • Quick-Shift Focus System for instant switching to manual-focus operation without any focus-mode changes, after the subject is captured in focus by the AF system
  • SP (Super Protect) coating applied to the front surface to repel dust, water and grease
