Features / Specifications
- High-magnification zoom
- 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. It uses an advanced optical design for providing high magnification in a compact, lightweight body and its easy operability and mobility make it suitable as a lens for everyday use.
- Simple drip-proof construction
- 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.
- Internal lens motor for smooth autofocus operation
- 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.
- High delineation performance
- 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.
- Round iris diaphragm for producing beautiful out-of-focus (bokeh) effect
- 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.
- Other features
- 1.Realizes minimum shooting distance of 0.4 m in the zoom range.
2.Uses "Quick-Shift Focus System" for enabling manual focus operation after focusing by AF without any switching operation.
3.Uses SP (super protect) coating for protecting the lens surface from water and dirt.
