The Cavision MMB4512FP 4 x 5.65 Matte Box Package for 15mm LWS Rods is designed to mount on 15mm rods (rods not included). The kit includes a 4 x 5.65" matte box with two filter stages, a 120 to 100mm step-down ring, a flexible lens donut, a top flag, and both left- and right-side flags. The matte box features one fixed and one rotating filter stage, and it includes one 4 x 4" and one 4 x 5.65" filter tray. The wide 120mm opening allows you to use it with a variety of lenses, using the proper antireflection or step-down donuts.
The included step-down ring allows you to clamp the matte box onto a lens with an outside front diameter of 100mm. For smaller lenses use the rod clamps to mount the matte box onto a set of 15mm LWS rods (not included). The included expandable top flag and side flags are useful additions that help protect your lens and filters from veiling glare or light strikes that can degrade your image.
