March 3, 2009
HOYA CORPORATION PENTAX Products is pleased
to announce the launch of the smc PENTAX-DA15mmF4ED AL Limited lens, designed
for exclusive use with its digital SLR cameras. The latest model of PENTAX’s
acclaimed Limited Lens series, this new lens inherits all the attributes of
this renowned series, including high-quality image reproduction and high-grade
lens-barrel finish, while providing users with a unique ultra-wide-angle perspective.
Ultra-wide-angle perspectiveWhen mounted on a PENTAX digital SLR camera body, this new lens offers a 23mm angle of view in the 35mm format, letting the photographer capture unique, eye-catching images with visual effects unique to ultra-wide-angle lenses, such as enhanced perspective and an emphasized depth of field. It can be effectively used to capture eye-catching images of such subjects as sweeping landscapes, magnificent architecture and confined interiors.
Limited Lens-series quality for distinctive visual description and a premium appearanceThe PENTAX Limited Lens series is designed for the ultimate in image reproduction, combining a series of mechanical and numerical evaluations with human assessment of test-shooting samples. True to this tradition, this new lens not only assures excellent image quality, but also produces sharp, clear images with outstanding contrast, even at the maximum aperture. This is because its optical design has been optimized for digital photography. In addition, its lens barrel, hood and cap are all made of a high-grade aluminum material and shaped for perfect proportions and striking beauty.
High-performance opticsThis lens incorporates a hybrid aspherical (AL) lens and an extra-low-dispersion (ED) glass optical element to assure high-quality image reproduction with minimal aberrations, including lateral chromatic aberration. Compared to other ultra-wide-angle lenses, its image distortion is also compensated to a minimal level.
Compact, lightweight designThanks to its newly developed optics, this lens is designed extremely compact and lightweight despite its ultra-wide-angle perspective. Since it has no dome-shaped protrusion at the front end, the photographer can mount commercial 49mm-diameter filters, including circular polarizing filters popular in landscape photography.
