Threads on to your camera or lens allowing the Matteblox to be directly attached.
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. Step-up rings (sold elsewhere on this planet) allow the Matteblox used with the 72mm Threaded Adapter to be mounted on just about any camera or lens with a thread (less than 72mm) on the end. We have a whole page of compatible cameras and lenses.
The 72mm Threaded Adapter has 72mm threads on both ends allowing screw on filters to be added either before or after the 72mm Threaded Adapter.
