An exceptional lens that delivers the sharp, high-contrast, well-defined images that faithfully depict the ambience of the scene
This lens has a 31mm focal length, which provides a slightly broader angle of view than more conventional 35mm lenses, to expand the possibilities of wide-angle photography.
This lens inherits the proven optics of the smc PENTAX-FA 31mm F1.8AL Limited, and incorporates high-grade optical components — such as glass-molded, aspherical elements and high-refraction, low-dispersion glass elements — to deliver sharp, well-defined images of small subjects, such as the very tips of a bare, leafless tree’s branches in winter.
The barrel, hood and cap are all made of high-grade aluminum, meticulously machined for an attractive appearance and beautiful texture. It also features a mount pointer with a shippoyaki (cloisonné) finish, which lets the user effortlessly and quickly mount the lens to a camera body.
The lens also features an aperture ring to make best use of the range of functions featured in K-mount film-format cameras.
HD coating for exceptional image rendition
This lens is treated with PENTAX-original HD coating.* Compared with conventional multi-layer coatings, this high-grade coating assures higher light transmittance and lower reflectance to deliver sharp, clear images free of flare and ghost images, even under such adverse lighting conditions as backlight. It elevates the imaging performance a further step up.
Round-shaped diaphragm for beautiful bokeh effect
This lens features a completely round-shaped diaphragm, which produces a natural, beautiful bokeh (defocus) effect in the images captured, while optimizing the imaging performance of the distinctive Limited-series optics contained within.SP coating to repel dust and protect lens surfaceApplied to the front optical element, the PENTAX-developed SP (Super Protect) coating effectively repels water and grease to keep the lens surface free of dust, water and oily substances. This coating is also highly resistant to abrasion and scratches, keeping the lens scratch-free.
