Pentax has added a new wide angle lens to its 645 medium format line. The new Pentax DA645 28-45mm f/4.5ED AW SR lens is the first ultra-wide-angle zoom lens for the Pentax digital medium format line.
The 28-45mm lens includes 17 optical elements in 12 groups, including two aspherical elements and two extra-low dispersion elements. Additionally, the lens features a built-in Shake Reduction mechanism that compensates for up to 3.5 shutter stops.
HD lens coatings on the new lens are designed to optimize light transmission and minimize reflections. The lens is also weather sealed with 11 seals to prevent dust and water from entering the lens, which is suited nicely to match the weather sealing on the new Pentax 645Z camera.
The new Pentax DA645 28-45mm f/4.5ED AW SR lens should be available this month for $4999.95. Check it out here at B&H Photo.
