Century 0AD-7220-00 (AD-7220-00 & AD722000) 72mm +2.0 Threaded Achromatic Diopter
Thread Size: 72mm
This line of advanced Achromatic Diopters provides video zoom lenses with more close-up range and magnification & while maintaining zoom capabilities — without compromising image quality.
Common single element diopters permit focusing at close camera-to-subject distances at the expense of image clarity & a pin cushioning effect occurs. Instead & Achromatic Diopters feature two highly corrected glass elements which minimize chromatic aberration and distortion & creating an image with edge-to-edge sharpness.
An Achromatic Diopter is essential whenever it is necessary to focus tightly on a small subject with a long lens - in tabletop, miniature and flat field photography.
Reduced working distance offers a range of shooting possibilities. Exceptionally crisp videography of small objects like jewelry or computer chips is now possible. A variety of industrial applications are made simpler, including remote, high-magnification visual inspection of hard-to-reach objects and manufacturing processes. For example, a camera and lens equipped with an Achromatic Diopter might be used to get an extremely accurate close-up view of signatures moving through a printing press.
