The Universal Lens Donut from Redrock Micro is made of flexible steel ring that snaps into your swing-away microMatteBox and features a light-proof cloth with a drawstring. The cloth fits around your lens, and the drawstring pulls the cloth tight around your lens to prevent light from reflecting off the back of your filters and degrading your image.
The donut is suitable for use with primes and zooms, and speeds 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.
Supports lenses up to 138mm front diameter
Supports zoom lenses with varying lengths
Works with your swing-away microMatteBox
