Rating: no ratingThanks to the incorporation of Pentax-original HD Coating — a newly developed high-grade multi-layer lens coating, and telescope-type optics, this super-telephoto lens delivers clear, well-defined images of distant subjects.
When mounted on a Pentax K-mount digital camera body, this super-telephoto lens offers an equivalent focal length of approximately 859mm in the 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. By incorporating two ED (extra-low dispersion) optical elements, it also delivers bright, high-resolution images even at the edges, while effectively minimising chromatic aberration.
