HD PENTAX-FA 77mmF1.8 Limited
A fun-to-use lens that makes the photo-shooting process more enjoyable, by delivering a varied image rendition for a given aperture, while faithfully depicting images such as the luster of shell buttons on a white shirtThis lens features a coating which effectively controls spherical aberration at different wavelengths to minimize color bleeding, while greatly reducing internal reflections by applying the most efficient black coating to the interior of the lens barrel. It is designed to faithfully reproduce delicate shades in white subjects, and clearly depict the brightest spot in highlight areas.
Because the lens inherits the outstanding rendition of warm colors from the smc PENTAX-FA 77mm F1.8 Limited, it is an ideal lens for portraiture or snapshots of people. It also features the PENTAX-original HD coating* to produce distinctive warm colors even under adverse conditions, and a completely round-shaped diaphragm to produce a natural, beautiful bokeh (defocus) effect from open aperture to F4.

While retaining the distinctive optical performance of the smc PENTAX-FA 77mm F1.8 Limited, this lens delivers exceptional imaging power, made possible by the meticulous attention PENTAX paid even to the details that can’t be measured simply by numerical factors.
