hi, i'm going to be buying the canon 450d this week. i am also thinking of getting the canon EF-S 55-250mm f4-5.6 IS lens. my question is should i buy the body only or go for the kit lens package, bearing in mind i am buying the EF-S 55-250mm f4-5.6 IS lens? will they complement each other or am i more likely to use the 55-250mm and forget about the kit lense? furthermore, does anyone have any recommendations for bags which will house both the 450d and the EF-S 55-250mm f4-5.6 IS lens? oh, one more question before i post this. should i get a uv filter or something to protect the lens? or will it come with a lens cap which should do the trick?
