This lens hood is made by Mennon. It's available in black or silver and is mounted on a 37mm filter. It even comes with a cap. I ordered it from EnjoyYourCamera.com in Germany.
Mennon also produces a screw-in lens hood with 37mm thread that fits the camcorder directly without the need for a filter. But since an UV or IR blocking filter also protects the lens I strongly suggest to use one.
Note that such a wide lens hood blocks the iAF sensor, the LED light and the flash. Since I don't use any of these that's not a problem for me. I don't film fast moving objects and I don't want the camera to change focus too quickly therefore I'm fine with the slower contrast auto focus through the lens.
