This is the lens hood that broke my rib. More truthfully this is the lens hood that I used to break my rib in my clumsiness. I was walking through some brush with a heavy pack full of cameras lenses and water. I stepped on some slippery dry grass next thing I knew I was rolling over on the ground and trying to get a breath. I had landed on the lens hood and broken a rib.

It was made of black ABS plastic and painted flat black inside. It really helped with lens flare.
