The Kenko KNT-20 is the latest addition to the growing line of Kenko brand lenses created for video and still digital cameras. The 2.0x telephoto lens features all glass optics, that are coated to reduce reflections and flare. These elements are housed in an all metal barrel that will stand up to years of use. The 52 mm mount thread makes this lens well suited to full-sized consumer video cameras, but it can be used with smaller video cameras if the appropriate step-up ring is used.
