Protect your lens and camera filters when they are installed in your Mirage matte box with this Filter Protector Kit from Tilta. The kit features an aluminum frame and a clear glass filter, and the assembly installs onto the front of the matte box using four integrated clips. It is designed to protect your 4 x 5.6" and circular filters, as well as the lens when not using a filter. The glass is completely clear and has no effect on the light entering the matte box.
