FOTGA Professional Matte box Swing Away Sunshade for 15mm Rod DSLR Rigs Kit with Universal Lens Donut Set

2 Dual-purpose filter trays, supporting 4x4" filter sizes (One of the trays allow rotating 180 degrees) The kit includes one French flag, and two adjustable side wings. Each of the three flaps can be positioned and locked in place so as to suit different focal lengths by providing the maximum amount of shading without getting in the way of the shot. For changing lenses quickly, the unit features a swing away design. Instead of moving the mounting position of the matte box, (which may be blocked by other rig accessories, or require rod extensions to fit), it can simply be slid outwards with just one screw to undo. It also allows height adjustable. A set of 4 “donut” rings are included. (Size at 103mm,76mm,64mm,51mm).By fitting one of these rings, light from the rear of the matte box can be blocked out, leaving only the camera lens protruding through. Donuts are slightly flexible, and the four sizes range to fit almost any lens diameter. Two pieces of free 15mm rods made of aluminum, length at 300mm
