Pentax HD DA 21mm F3.2 AL Black Lens

With precision and high-performance optics, the Pentax 21mm F3.2 lens measures only one inch in length and weighs a mere 4.9 ounces. It is the ideal choice for carry- everywhere, instantaneous wide angle or snapshot photography. The versatile angle of view produces natural images with a moderate perspective, or an expanded depth of field, making it ideal for many different types of subjects, stories, landscapes and life’s special occasions.

High-grade HD coating for exceptional image rendition
All lenses are treated with HD coating, a high-grade multi-layer lens coating that assures higher light transmittance and lower reflectance than conventional multi-layer coatings. As the result, they produce sharp, clear images free of flare and ghost images, even under such adverse lighting conditions as backlight.

Round-shaped diaphragm
All lenses feature a completely round-shaped diaphragm to optimize the performance of their distinctive optics. This diaphragm produces a natural, beautiful bokeh (out-of-focus) effect, while minimizing the streaking effect of point light sources.

Premium quality of the Limited Lens-series
While inheriting the design concept of the Limited Lens series, these lenses were designed by combining a series of mechanical and numerical evaluations with human assessment of test-shooting samples to assure the ultimate in image reproduction. Their optical design has been optimized for digital photography to deliver sharp, clear images with outstanding contrast, even at the maximum aperture. In addition, their lens barrel, hood and cap are all made of a high-grade aluminum material, hand-machined for perfect proportions and beautiful texture.
