Denver, Colorado August 4, 2014 -- Today, RICOH IMAGING
AMERICAS CORPORATION announces the addition of the HD PENTAX DA645 28-45mmF4.5ED AW SR to the 645 interchangeable lens series. This ultra-wide-angle zoom lens is the latest in the PENTAX 645 line-up and is engineered for use with PENTAX medium-format, digital SLR cameras. Now Pentax 645
medium-format shooters will have a new high-quality lens to expand their distinct format shooting.
This new lens provides focal lengths from 22mm to 35.5mm in the 35mm format, and is the first
ultra-wide-angle zoom lens (approximately 1.6X zoom ratio) designed for use with our medium-format digital cameras. 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 (Shake Reduction) mechanism has been incorporated into this exceptional lens, which effectively compensates for camera shake up to approximately 3.5 shutter stops.
Advanced, multi-layer, HD lens coatings are applied to optimize light transmission and
minimize reflection. Paired with this with the PENTAX-exclusive, high grade Aero Bright Coating, this lens delivers the dynamic, super-high-resolution images that are only madepossible by medium-format digital SLR cameras.
Eleven special seals are used to effectively prevent the penetration of dust and water into the lens interior offering superior dependability and durability under a wide variety of shooting condition empowering the photographer to capture various images ranging from those inside the studio to sweeping landscapes without concern.
"With the rapid adoption of the PENTAX 645Z, it is essential that we continue to address the needs of the professional photographer by providing premier lens choices.
The launch of the PENTAX 28-45 mm lens reinforces our commitment to the future of medium-format photography" said Jim Malcolm, Executive Vice President, Ricoh Imaging Americas Corporation.
