smc PENTAX-FA645 80-160mm F4.5

This medium telephoto zoom lens transitions from 63mm to 126.55mm, with a 35mm equivalent focal length, offers a f/4.5 maximum aperture, and features autofocus extending down to f/32. It uses extra-low dispersion (ED) glass and extraordinary-low dispersion glass in the optical system to effectively correct the various types of aberrations, and a ghostless coating is used for effectively preventing reflections on the lens inner surface. This enables a sharp image with high contrast. Focus as close as 1.0m when using this lens, which gives consistency to out-of-focus areas with an eight-blade diaphragm. Photographers may add 77mm filters with the front thread and, when the hood is attached, can easily adjust all by turning the front of the lens.
