Designed for still lenses, this donut ring screws onto the inner thread of the lens to step up the diameter to 114mm to be used with a matte box.
Threaded Donut Rings
The 114mm Threaded Donut Rings are an optional accessory designed to screw into the inner threading of your lens to change the outer diameter interface with any matte box to 114mm.
The front end is designed with the absolute minimum overhang to allow for maximum field of view and the precision standard thread allows for quick and easy attachment to the lens.
The ring is even compatible with our Black Hole donut using a separate adapter ring that helps secure the Black Hole when expanded.
Made from anodised aluminium, this ring is lightweight and built with no compromise to offer you maximum durability.
