The Pentax 28-45mm f4.5 ED AW SR HD DA lens with 645 mount is an ultra-wide-angle lens with SR Shake Reduction for use with the 645D and 645Z medium-format DSLR cameras. This weather-resistant lens provides a 35mm equivalent focal length of 22-35.5mm, making it great for capturing a wide variety of scenes and subjects, in particular images with an exaggerated perspective. Its optics consists of 17 elements in 12 groups, including two high-performance aspherical elements and two extra-low dispersion elements. In addition, the Pentax-innovated SR mechanism has been incorporated into this versatile lens, which effectively compensates for camera shake up to approximately 3.5 shutter stops.

This is an ultra wide-angle zoom lens designed specifically for degital use, featuring the best of Pentax lens technology.
Providing focal lengths from 22mm to 35.5mm in the 35mm format, this is exclusively designed for digital imaging. Its image circle is optimised for an image sensor of the new Pentax 645Z medium-format digital SLR camera, and a number of Pentax developed technologies including advanced lens coatings are incorporated, to deliver super-high-resolution images made possible only by medium-format digital SLR cameras.

First ultra-wide-angle zoom lens for use with medium-format digital SLR cameras
This zoom lens offers a zoom ratio of approximately 1.6 times to cover ultra-wide-angle to wide-angle ranges (for focal lengths of 22mm to 35.5mm in the 35mm, when mounted on a Pentax 645Z or 645D camera body). With visual effects unique to wide-angle lenses, including exaggerated perspective and expanded depth-of-field, this lens can be used for a wide variety of scenes and subjects, such as sweeping landscapes and cramped rooms, adding more versatility to advanced medium-format digital SLR photography.

State-of-the-art optical design to optimize super-high-resolution images
Designed as the HD Pentax DA-series model in the Pentax 645 lens series, this lens's image circle is optimized for the image sensor of the Pentax 645Z camera body. Its optics consists of 17 elements in 12 groups, including two high-performance aspherical elements and two ED (Extra-low Dispersion) elements, to enhance image resolution and brightness at edges, while minimizing various aberrations. Coupled with innovative lens coatings and an anti-reflective coating applied to the interior of the lens barrel, this lens is designed to bring out the best performance of medium-format digital SLR cameras.

HD Coating and Aero Bright Coating to optimize light transmittance and minimise reflection
This lens is treated with the high-grade, multi-layer HD Coating to optimize light transmittance and minimise reflection. This coating delivers sharp, clear images free of flare and ghost images, even under demanding lighting conditions such as backlight. By coupling this coating with the Pentax exclusive, high-grade Aero Bright Coating, this lens is designed to assure exceptionally high light transmittance and super-low refraction.
