Lens hood for GS150
 

I recently purchased a Panasonic PV-GS150 and a Kenko WA lens. I would like to put a lens hood on there as there is a considerable amount of lens flare when I'm out in regular daylight. Does anyone have any recommendations?

Does the Kenko have filter threads? If so, what size? You can find examples of hoods for Panasonics and wide angle lenses (click) here.

I could even do with just getting a lens hood for the camera without using the WA lens. Are there any hoods that would thread onto this camera? Its a 37mm and everything else I've seen is for either a smaller thread, or a larger one.
