Chris writes in shares Fotga's latest MatteBox. Just over $220 dollars, it offers the usual dual
rotating filter trays, three flags, and mounts to standard 15mm rods. Instead of the massive bracket on one side, the Fotga uses a very low profile swing away that sits just above the rod clamp for faster lens changes.
In the specs it claims to have +/- 10mm of height adjustments, but I don't see how that could be done. There's some additional photos at the eBay product page (Click Here).
