Features
Internal lens motor for smooth autofocus operation
Round iris diaphragm for producing beautiful out-of-focus (bokeh) effect
High delineation performance
Simple drip-proof construction
High-magnification zoom
A DC motor for the autofocus (AF) incorporated within the lens enables smooth autofocus operation (Note 1). A non-rotating mechanism is also used for locking the focus ring during autofocus so that the lens is held in the same position as manual focus.
Note 1: The compatible models are the K-70/K-1/K-3II/K-3/K-S2/K-S1/K-50/K-30/K-5 II/K-5IIs/K-5/K-01/K-7/K-r/K-x/K-m/K20D/K200D/K10D FW Ver.1.30/K100D Super. If attached to other cameras, focusing is performed using the manual focus.
The optical system uses one ED (extra-low dispersion) glass and one hybrid aspherical lens (AL) and one glass mold aspherical lens. This system enables correcting of various types of aberration and high delineation performance in a compact body design.
This lens uses a round diaphragm for reducing the beams of light when shooting point light sources for enabling a more natural out-of-focus (bokeh) effect.
This lens uses a simple drip-proof construction for preventing water from getting inside the lens. Combined with PENTAX digital SLR cameras also using a drip-proof construction enables use in rainy or foggy conditions, or other locations exposed to water for enhanced durability and reliability.
Attaching this lens to a PENTAX digital SLR camera enables use as a 7.5x high-magnification zoom lens with a focal length equivalent to 27.5mm (wide) to 207mm (telephoto) in 35mm film format. This lens is suitable for a wide range of typical photographic situations, from landscapes, snapshots, and portraits to sports events.
