Wooden Camera UMB-1 Mattebox Clamp On Ring (143-80mm)

The 143-80mm UMB-1 Matte Box Clamp-On Ring from Wooden Camera enables you to use your base or swing-away version of the UMB-1 Universal Matte Box as a clamp-on matte box with a lens with a front outer diameter of 80mm. The clamp-on ring is made from ABS plastic for a combination of strength and durability and features a split ring design for a secure grip and built-in baffles to prevent light leaks.

Compatibility

UMB-1 Universal Matte Box Base and Swing-Away versions.

Functionality

The split ring design allows the clamp-on ring to compress while evenly distributing the clamping force on your lenses barrel. The baffles (overlapping areas) prevent light from leaking from behind the camera and fogging filters or degrading your image.
