What lens is this

[DEDFX]

Kind of a strange question but I have seen this effect in many movies but I have no idea how to do it, It's focused on a character who looks slightly distorted with everything else in view looking normal. You can see it in this video http://www.youtube.com/watch?v=0o2V3Uj3xjA in the 18-21 second shot and the 34-37 second shot. Thanks for the help.

It could be a very slight fisheye lens, or even a fisheye effect done in post-production. I know Ulead Videostudio 11 plus has a fisheye effect.

Yeah it sorta looks like it, FCP has fisheye and I guess I could do it in post.
