Converts most 72mm screw on filters into a Matteblox compatible filter. Designed to reduce vignetting on Panasonic's AG-DVX100 when a screw on filter is already mounted on the camera.
Adaption
This adapter allows the Matteblox to be used with Canon's XL1/XL1s/XL2, Panasonic's AG-DVX100 and AG-DVC80 and many other cameras and lenses with 72mm threads on the end.
