I'm looking for a fisheye converter, mostly for some unique portraiture concepts I have in mind. What I want to know is should I go for a 0.25x or 0.42x? I'm not really sure what the differences are, so if someone could explain that, it'd be handy too. I guess one day I'll be buying a fisheye lens, but for now the converter will do. My current lenses are: Canon 18-55mm, 75-300mm, Tamron 90mm.
