This APS-C optimized Limited zoom lens is the first to feature a versatile focal length of 20-40mm. With two-times zoom coverage this lens offers focal length coverage from 30.5 to 61.5mm in the 35mm format when mounted on a PENTAX K-series DSLR. Thus, it provides the most frequently used focal lengths for a variety of subjects settings and creative perspectives in a Limited Series lens, all housed in a durable PENTAX weather-sealed body with state-of-the-art HD coating.
The large f/2.8 maximum aperture and rounded diaphragm blades produce stunning bokeh for exceptional visual expression. The lens barrel, hood and cap are made of a high-grade aluminum material, and hand-machined for perfect proportions and beautiful texture. The zoom ring (see the mid-section of the lens barrel) features a series of knurled grooves to facilitate zooming operation. Like all Limited Series lenses, this lens is available in a sleek silver or classic black.
Treated with PENTAX-developed HD coating, a high-grade, multi-layer coating that reduces reflectance in the visible light spectrum to less than 50% of that of conventional multi-layer coatings, so you can capture crisp, high-contrast images free of flare and ghosting, even under demanding lighting conditions.
PENTAX-original weather-resistant construction includes 7 special seals to prevent intrusion of water, moisture and dust.
PENTAX-original Quick-Shift Focus System allows instant switching from autofocus to manual focus operation.
Shoot discreetly with in-lens, direct current (DC) Auto Focus motor operation for smooth and quiet performance.
ED (Extra-low Dispersion) glass and a super-low dispersion glass element in the lens optics deliver clear, high resolution imagery with edge-to-edge sharpness, throughout the entire zoom range.
PENTAX-original SP (Super Protect) coating repels dust, water and grease to keep your lens clean and your image quality at its peak.
