The Fujifilm Fujinon C22x17B-Y41 is a long zoom lens for industrial cameras with C-type lens mounts. It was designed primarily for 1/2-inch CCD systems but it can be used on 2/3-inch and 1-inch systems as well. This lens can be preset for specific zoom, focus and iris positions. It also has video-type auto iris and a built-in ND filter that brings the effective minimum aperture to f/3000. It can focus as close as about 10' (3m).
