Hey guys, I am about to pick up a Canon 40d and was wondering if the lens kit (the EF 28-135mm) is worth picking up. My situation? I have: 12-24mm wide angle 50mm f/1.8 18-55mm (Digital Rebel XT Kit lens) 70-300mm 100mm Macro I need a replacement for the 18-55mm as I am not happy with that lens. Ideally I would like the 17-105mm L lens (or the 17-70mm L) so would it be worth waiting 6 months or so to pick this up? Or just go for the 28-135mm and make do Thanks for any advice!
