Cavision 85mm to 52mm Threaded Metal Deep Offset Step-Up Adapter Ring

This adapter ring is designed for use with lenses that have a 52 mm filter thread and connects to a matte box with an 85 mm opening.

Made of aluminum, it allows the matte box to be positioned further back relative to the lens front, which can help prevent vignetting when using wider angle DSLR lenses. The ring screws onto the lens front filter thread. Note: Some lenses may have obstructions that prevent this adapter from fitting.
