Ultra wide-angle perspective
This new lens offers a 23mm angle of view (in the 35mm format) for eye-catching wide-angle images. Enjoy visual effects unique to ultra wide-angle lenses such as enhanced perspective and an expanded depth of field. This lens is perfect for capturing sweeping landscapes, magnificent architecture and confined interiors.

Limited Lens series quality
The Pentax Limited Lens series is designed for the ultimate in image reproduction. True to the Limited lens tradition, this new lens not only assures excellent image quality, but also produces sharp, clear images with minimal distortion and outstanding contrast even at the maximum aperture. The optical design has been optimized for digital photography, and the barrel, built-in hood, and cap are all made of a high-grade aluminum material that is shaped for perfect proportions.

High-performance optics
This lens incorporates a hybrid aspherical (AL) lens and an extra-low-dispersion (ED) glass optical element to assure high-quality images with minimal aberrations, including lateral chromatic aberration. Compared with other ultra wide-angle lenses, image distortion is also extremely low.

Compact, lightweight design
With newly developed optics, this ultra wide-angle lens design is extremely compact and lightweight. It has no dome-shaped protrusion on the objective element, allowing the photographer to easily mount any 49mm diameter filters, including circular polarizing filters which are popular in landscape photography.

Minimum focusing distance of 0.5 feet (18 centimeters) for close-up photography

Pentax-developed Quick-Shift Focus System for instant switching to manual-focus operation after the subject is acquired by the AF system
