What fisheye to buy?

[Eden.z]

Hi, I'm trying to chose a fisheye to my Sony Handycam DCR-SR47, for skateboard photography.
I already found four lenses by Opteka, all of them are abut 37mm and I dont know if it good for what I need it.
If someone got to use one of those lenses I'll be happy to hear a review.
Thanks [=
