The HD Pentax-DA 560mm F5.6 ED AW is a new super-telephoto lens for Pentax K-mount digital cameras. When mounted on a Pentax K-mount digital camera body, this super-telephoto lens offers an equivalent focal length of approximately 859mm in 35mm format. Since the lens’ unique telescope-type optics require fewer optical elements than conventional lenses, it delivers sharp, well-defined images, particularly of distant subjects, the company claims. The HD Pentax-DA 560mm F5.6 ED AW lens is treated with HD Coating, a new high-grade multi-layer lens coating developed by Pentax. A new addition to the AW (All Weather) series, this lens also features a dustproof, weather-resistant construction with 29 special seals. The HD Pentax-DA 560mm F5.6 ED AW will be available from early December for £5,999.99/$6999.95.
