The Cavision MBF3 French Flag is a flag for the MB385P/M 3x3 Matte Box; it can be positioned to cover the matte box or at various angles depending on the user's application.
This flag is only compatible with the MB385P/M matte box and LH100P/M lens hood, as both the matte box and lens hood have the same rubber shade where the MBF-3 is attached.
