The M2 Matte Box from YELANGU mounts to standard 15mm rod systems using a height-adjustable swing-away bracket, and accepts lenses up to 100mm in diameter. It features two rotating 4 x 4″ filter trays. The swing-away bracket allows you to move the matte box out of the way during lens changes, without having to remove it from the rods. The unit’s height can be adjusted to support different-sized cameras and lenses. The top flag and two side flags, which are made of durable metal, block unwanted light to prevent glare and lens flare. This matte box is suitable for use with DV and HD cameras or DSLRs.
