Wooden Camera UMB-1 Universal Matte Box Cloth Donut for Non-Standard Lens - 143mm

The Wooden Camera UMB-1 Universal Matte Box Cloth Donut for Non-Standard Lens - 143mm snaps onto any matte box with a 143mm rerar opening and makes any lenses with an outer diameter from 72 to 138mm usable. The black cloth comes with a drawstring that helps form four thumbloops for adjustment. Because of this, it can fit snugly around your lens to help prevent light from reflecting off the back of your filters. This will help prevent degradation of your image.

The donut is suitable for use with primes and zooms, and it can speed lens changes as you don't have to worry about finding the specific donut for each of your lenses. Additionally, when using lenses with either focus or zoom travel, the universal donut will expand and contract with the movement of the lens, ensuring a light-tight fit.
