This 77 to 114mm Threaded Adapter Ring from SmallRig is a step-up ring that allows you to mount the SmallRig 2660 matte box onto your lens, and it allows you to add a filter with a thread diameter of 77mm. The adapter fits the 114mm matte box opening and allows you to mount your matte box closer to the front of your lens, reducing the possibility of vignetting with wide lenses. It features durable aluminum construction and a matte finish to minimize glare and reflections.

Note:

Focal lengths under 16mm may cause vignetting.
