I've talked with a few guys online that insist if the lens shield can be removed, I'll be able to find a filter to screw on in it's place. I think most people overlook the fact that the lens is behind the clear shield that is generally incorrectly refered to as the lens.
From what I've seen of hoods, they actually make a huge improvements in the overall quality of your shots. I've got a brother that's a photographer and found out it's really easy to make your own with empty bottles and plastic containers. Just need a razor cutter and flat black spray paint.
I'll try it and share my results.
