Description
With the Pentax DA 645 28-45 mm F 4.5 HD ED AW, Pentax introduces an ultra-wide angle zoom lens for Pentax 645 d and Pentax 645Z. The focal length is similar to 22-35, 5 mm in the 35 mm equivalent and the construction is dust and water resistant.
The Pentax DA 645 28-45 mm has a 6 x optical zoom of 1, and a maximum aperture of f/4.5 over the zoom range. The lens is made up of 17 elements, divided in 12 groups, including two aspherical elements and two extra-low dispersion (ED) elements. This optimizes the image resolution and brightness at the edges and minimizes the aberration. The lens is treated with a HD and Aero Bright coating for high light transmission and minimal refraction.
The lens has nine rounded diaphragm blades for a nice bokeh. The Pentax DA 645 28-45 mm F4.5 has Pentax's own HD image stabilizer SR (Shake Reduction). The camera's sharpness is minimized and vibration is compensated to about 3.5 shutter steps.

- Suitable for 645Z and Pentax 645D
- Aperture range f/4.5-32
- 17 elements spread over 12 groups, including 2 aspherical and 2 ED elements.
