Cavision LH-80 is a rubber lens hood that fits over lenses with an outside diameter of 80mm, including the Canon WD-58 and Kenko 0.5x lens converters. The shade protects the lens from stray light minimizing glare and lens flares.
Will this fit a Nikon S9X5.5B1EMS-20 2/3" lens? If not do you have something similar that will?

Can you add a french flag to this sunshade? If not, do you have any other sunshade to which you can attach a french flag?
does this hood have threads for a filter lens?
I'm not sure I understand your question. Are you asking if this unit threads onto a lens or just has threads for mounting filters? The Cavision LH-80 is a rubber lens hood that fits over lenses with an outside diameter of 80mm (the mount is not threaded). This unit appears to include 82mm diameter filter threads on the inside for mounting filters.
