Genustech GFFW French Flag Assembly

A matte box without a top flag lets light spill straight down onto the front element from any source above the frame line, and the GFFW is the fix for the GML Matte Box Lite: a full French flag assembly that mounts to the box and blocks that overhead light before it reaches the lens.

It installs with the included instruction sheet covering mounting and adjustment, and works across the adapter ring range the GML system supports, from 52mm up to 82mm lenses.
