Wide Angle Lens HELP!
 

I've Been Looking for a wide angle lens for a 37mm digital handicam,
I'm kind of new to film and photography. Most of the .45x lenses I've
looked at are fisheye lenses, are all .45x lenses fisheye ? or are
they diffrent from just normal .45x wide angle lenses. Also Is the
lower the number (.45x) the wider the picture or do I want one with
the highest number (.6x)?
