The first two-times zoom lens of the Limited Lens series

With its two-times zoom coverage from 20mm to 40mm, this lens offers a focal-length coverage from 30.5mm to 61.5mm (in the 35mm format) when mounted on a PENTAX K-series lens-interchangeable digital cameras body. It provides the most frequently used focal lengths required for many popular applications, such as scenic photography, snapshots and portraiture, making it the ideal choice as an all-purpose, everyday lens.

Acclaimed Limited Lens-series quality for superb visual description and premium appearance

Inheriting the design concept of the Limited Lens series, this lens is designed with an optical construction that faithfully reproduces the feeling of depth while minimizing astigmatism over the entire zoom range. It allows the photographer to optimize the subject’s visual description, by making its appearance softer at larger apertures and sharper at smaller apertures. Its lens barrel, hood and cap are made of a high-grade aluminum material, and hand-machined for perfect proportions and beautiful texture. Positioned in the mid-section of the lens barrel, the zoom ring features a series of knurled grooves to facilitate zooming operation.

State-of-the-art optical technology

The lens has been treated with the PENTAX-developed HD coating*, a high-grade, multi-layer coating that reduces reflectance in the visible light spectrum to less than 50 percent of that of conventional multi-layer coatings. This allows the user to capture crisp, high-contrast images free of flare and ghost images, even under such adverse lighting conditions as backlight. It also incorporates an ED (Extra-low Dispersion) glass and a super-low-dispersion glass element in its optics to deliver clear, high-resolution images with edge-to-edge sharpness, while effectively compensating for chromatic aberrations over the entire zoom range.

The first weather-resistant lens in the Limited Lens series

This lens is the first Limited Lens-series model to feature a weather-resistant construction, with seven special seals to prevent the intrusion of water and moisture into the lens interior. By mounting it on a PENTAX weather-resistant digital SLR camera body, the user is assured of greater durability and reliability when shooting in the rain or mist, as well as at locations subject to spray or splashes.

Other features

Smooth, quiet AF operation using a lens-installed AF driving motor.
Round-shaped diaphragm to produce a natural, beautiful bokeh (blur) effect, while minimizing the streaking effect of point light sources.
The lens features the Quick-Shift Focus System, which allows the user to instantly switch to manual-focus operation after the subject is captured in focus by the camera’s AF system.
SP (Super Protect) coating to keep the front surface free of dust and stains.
A choice of black or silver color.
