I'm on the verge of buying a Canon EOS 20D. Up to now I've been using a Fujifinepix F700, which I cant fault for what I want to do, but wanting to move on a wee bit decided to spend a bit of money on a DSLR.  I've dusted down my old Fender Squire and Amp to help pay for it!   Anyway I was wanting to know if you own a Canon 20D, what lens would you recommend as good all rounder mainly for landscape / portrait shots. It looks like a bit of a mine-field at first.

I may buy the body only, or as part of a kit with a lens included but either way , I'm not sure what  spec of lens I should be looking for.  I've been volunteered to take someones wedding photos too, I think I'm more nervous of doing this than I was at my own wedding, so I want to make sure I give them some decent pictures.  Also, is it normal to have say 3 or 4 lenses as part of your outfit?

Thanks for any tips/help
