I'm new to cameras and photography. I've been thinking of shooting cars lately, as that's another hobbie of mine. Wide-angle lenses make cars look especially nice. I don't know anything about wide-angle lenses. Can anybody teach me and tell me a bit about them and how they work? I've got a Nikon D50 and it came with a kit lens (18-55mm zoom). I've seen some wide-angle lenses that are 24mm, etc. Seen as though I've got 18mm as my lowest, does that mean I can make some shots wide-angle-looking with my kit lens? Thanks!
