High-Performance Lenses
08 WIDE ZOOM
- Zoom
- High-Performance
This wide angle zoom lens can be used in constricted spaces where it is difficult to obtain separation from the subject, landscapes that emphasize a sense of vastness and perspective, and more.
Three glass-molded aspherical lenses are used for enabling a lens length of about 38mm, which is the shortest in the Q Mount Zoom lens lineup, and for providing a compact, lightweight design that weighs only about 75g. This lens is an easily portable size and has a focal length equivalent to 17.5mm to 27mm in the 35mm film format to enable usage in a wide variety of situations, including constricted spaces where it is difficult to obtain separation from the subject, landscapes that emphasize a sense of vastness and perspective, and more. The lens uses the cam barrel made of machined aluminum materials for a smooth and elegant tactile sensation when operating.

Features / Specifications
- 1. Compact, lightweight design
- Three glass-molded aspherical lenses are used for enabling a lens length of about 38mm, which is the shortest in the Q Mount Zoom lens lineup, and providing a compact, lightweight design with a weight of only about 75g.
This lens is an easily portable size and has a focal length equivalent to 17.5mm to 27mm in the 35mm film format (when attached to a PENTAX Q7 mount digital SLR camera) to enable usage in a wide variety of situations, including constricted spaces where it is difficult to obtain separation from the subject, landscapes that emphasize a sense of vastness and perspective, and more.
The lens also features a cam barrel made of a machined aluminum material for a smooth and elegant tactile sensation when operating. - 2. High delineation performance
- The first lens uses a glass-molded aspherical lens of uneven thickness for dramatically reducing the distortion.
The optical system also uses two ED (extra-low dispersion) glass lenses and one extraordinary low-dispersion glass lens for correcting the chromatic aberration over the entire zoom range and also enabling sharp, crystal-clear images from the center all the way to the edges. - 3. Other features
- [1] An inner focus system is used for providing a high-speed, quiet auto focus drive
[2] "Quick-Shift Focus System" for enabling manual focus operation after focusing by AF without any switching operation
[3] SP (Super Protect) coating for protecting the lens surface from water and dirt
[4] Built-in lens shutter using a ND filter and multi-level iris diaphragm
