The Ivation Matte Box M3 is a professional matte box for filming with DSLRs and system cameras. It shields your camera from sunlight during shootings to prevent lens reflections (lens flares). The degree of shielding can be freely selected by adjusting the three movable barn doors individually. The matte box fits all lenses with filter thread not exceeding 86mm, and it is compatible with wide-angle lenses. It can also fit lenses of varying diameters with adapter rings (available separately). It features two filter stages with fixed holders that support 4 x 4" filter trays. One filter stage is fixed, while the other supports 360° rotation.
The matte box easily mounts onto 15mm rails using a height-adjustable swing-away bracket. The swing away design allows you to make quick lens changes and simply move the matte box away from your lens when you're not using it without having to detach it from your system. The matte box's height can be adjusted to match the lens of your camera when mounted on a 15mm rod system.
