105 mm to M72 Threaded step down XL ring
Item Code: 0250-0146
When using a matte box as clip-on, step down rings can be necessary, with or without thread. This XL ring is required when using a MB-2XX matte box (with 105 mm front diameter) as a clip-on on a lens with internal M72 thread. The shape of the ring is XL for compatibility with large lens fronts such as the Sony HVR-270(S).
