Pentax announces new DA645 25mm f/4 lens for exclusive use with Pentax 645D medium format digital SLR camera
Pentax today announced the introduction of its new DA645 25mm f/4 lens, designed and optimized for exclusive use with its popular 645D medium format digital SLR camera. By combining its ultra-wide perspective with exclusive Pentax Super Multi-Coating (smc), Aspherical Elements (AL), Supersonic Motor Drive (SDM), and all-weather (AW) construction, Pentax has created a lens that will render super-sharp images with performance levels photographers have come to expect from original Pentax lenses.The new Pentax DA645 25mm f/4 lens features a conveniently placed interchangeable built-in filter holder (including a 40.5mm diameter circular polarizing filter) located within its barrel.
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 lens also features fully automatic diaphragm control; a built-in lens hood optimally shaped for its angle-of-view when used with the 645D; a Quick-shift Focus system for instant switching between auto and manual focus; 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 incorporates two high-performance aspherical optical elements, which provide exceptional image-resolving power with outstanding brightness levels even at the edges, while keeping various aberrations to a minimum. As the newest addition to the AW (all-weather) series, this new lens includes dustproof and weather-resistant construction with 11 special seals to prevent the intrusion of dust and water into the lens interior. The new Pentax DA645 25mm f/4 lens will be available at retail outlets nationwide and online in late March with a suggested retail price of $4,999.99.
