Product Features in Detail

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
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.

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.

SP Lens Coating
The PENTAX SP (Super Protect) coating on the front and rear lens elements repels dust, water and grease to keep your lens clean and your images sharp.

DC Autofocus Motor
Smooth autofocus operation using an AF driving motor (DC motor) installed in the lens barrel.

Rounded Diaphragm Blades
Enhanced with a rounded nine-blade diaphragm at the wide apertures for optimal optical performance and gorgeous bokeh effects while minimizing the streaking effect of point light sources.
