4×5.65 Carbon Fiber Matte Box (Clamp-on)

This 4×5.65 carbon fiber mat box is designed to attach directly to a full-size film lens to make it as light and unobtrusive as possible

It includes several lens adapter rings to fit most standard tip diameter sizes.

Additional size backs can be purchased separately.

Not only do these adapter rings attach the matte box directly to the lens, but they also eliminate the need for lens donuts.

A French flag top is added to the flame protection packaging.

It also includes a 15mm rod attachment if you want to mount the matte box via a LWS rod.
