The Simmod Pro SimRing  screws onto the front filter thread of your lens and acts as a step up ring to provide a 77mm front internal thread for screw on accessories, while maintaining a consistent 80mm outer diameter for matte box compatibility.

 

Simply put, our 80mm Rings are designed for precision and optimum fit, smoothness, and compatibility with any matte box system on the market. Converting your front outer diameter to 80mm is a quick and inexpensive upgrade that adds purpose and convenience to any lens set up.

 

To select the size you need, you must determine the front filter diameter of your lens.  Please follow the resources below as a reference.
