Denver, CO—Pentax Ricoh Imaging introduced its new DA645 25mm f/4 lens, designed and optimized for exclusive use with its 645D medium-format digital SLR camera. Pentax combined its ultrawide perspective with super multi-coating (smc), aspherical elements (AL), supersonic direct-drive motor (SDM) and all-weather (AW) construction to create this lens.

When mounted on the Pentax 645D medium-format digital SLR camera body, the DA645 25mm f/4 AL [IF] SDM AW lens provides a focal length of approximately 19.5mm in the 35mm format, the widest perspective available with the 645D. Photographers now have greater creative flexibility when shooing landscapes or photographing in confined areas with minimal room to move.

“The DA645 25mm f/4 lens is completely optimized for use with the Pentax 645D digital SLR camera to render outstanding sharpness and clarity, even along its edges,” explained John Carlson, sr. manager of Sales and Marketing, Pentax. “Its 95º angle of view offers the widest perspective available for use with the camera, providing photographers with greater creative flexibility in a variety of shooting environments whether they are in a studio or out on location.”

Carlson added that the lens also offers precision engineering and glass elements. The DA645 25mm f/4 lens incorporates two aspherical optical elements, which provide image-resolving power with “outstanding” brightness levels even at the edges, while keeping various aberrations to a minimum. In addition, the lens is treated with Pentax Aero Bright coating to help ensure antireflection performance over a broader wavelength range for images that are more brilliant and higher quality than those produced by previous models.  Additional lens coatings and antireflective materials are applied to create a lens that is totally optimized for the 645D camera.

As the newest addition to the AW (all-weather) series, this lens includes dustproof and weather-resistant construction with 11 special seals to prevent the intrusion of dust and water into its interior.

Additional features include: a conveniently placed interchangeable built-in filter holder (including a 40.5mm diameter circular polarizing filter) located within its barrel; fully automatic diaphragm control; a built-in lens hood shaped for its angle of view when used with the 645D; a quick-shift focus system for instant switching between auto and manual focus; a rounded diaphragm to produce an attractive bokeh for enhanced appearance of a photograph’s out-of-focus areas; and a special protect (SP) coating applied to the front surface of the lens to repel dust, water and grease.

The Pentax DA645 25mm f/4 lens carries an MSRP of $4,999.95. pentaximaging.com
