Century Optics +3.5 Achromatic Close-up Diopter for 72mm Thread Mount
Your card will only be charged once item ships.
For maximum magnification and image clarity, these Macro Zoom Attachments give your lenses more close-up range, while preserving zoom capabilities. Available in +2.0, and +3.5 magnifications, Century Achromatic Diopters are essential whenever you need to focus tightly on a small object in tabletop, miniature, and flat field videography. Integral 72mm threads make it easy to connect the diopters to the front of your lens. Two or more diopters can be stacked on the front of the lens for even more magnification.
Common single element diopters permit focusing at close camera-to-subject distances at the expense of image clarity. Instead, Achromatic Diopters feature two highly corrected glass elements which minimize chromatic aberration and distortion.
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.
Choose one or both 72mm threaded +2 or +3.5 strengths. Also available, step-up rings for lens fronts with diameters of 62mm & 67mm.
