Hi Everyone, I started out a couple of years ago with a 1000D twin lens kit. Along the way I've bought a 10-22, a 50 , small and large speedlites and transmitter. Today I jumped in and splurged on a 7D and a 70-200 f/2.8 L IS II and by the end of the year I'm hoping to buy a EF-S 17-55mm f/2.8 IS. My question is, now that I've graduated up from my low-level twin lenses to more expensive, better performing models, can my 1000D still serve as my backup body, or is it just too basic? Thanks, Amanda
