NYC, NY (PRWEB) February 12, 2013
Pentax K-mount lens is the HD Pentax DA 560mm f/5.6 ED AW HD super-telephoto lens with a 35mm-equivalent 859mm focal length.
The lens has an AF driving motor installed in its barrel, which promotes smooth autofocus operation. It also features a multi-layer HD Coating, yielding sharp and clear images free of flare and ghosting.
The Pentax DA 560mm f/5.6 ED AW telescope-type optical design and two extra-low dispersion (ED) lens elements limit chromatic aberration around the image, and its rounded diaphragm blades provide smooth bokeh in the out-of-focus areas. The lens barrel is also equipped with a removable C-PL circular polarizing filter holder for using filters that further reduce unwanted reflections. The lens also features 29 special seals that make it both dust and weather resistant.
