I love this mattebox but there are two things I would like for it. A set of masks to control stray light better and the option for metal filter holders. I actually like the plastic ones when I need to go really lightweight but I would like to have metal ones with really tight tolerances for when weight isn't an issue. I may have a source for doing this work but I need to know how much interest is out there for these accessories. Add your name to the list here and if we get enough people I think we can get this done and the mattebox will get that much better.
