Having recently upgraded my main body, my intention is to de-grip my 450d, and add zoom to it for a light vacation camera rig. I'm not a big zoom guy - mostly primes. I have the Canon 28-105 f3.5-4.5 - which came with the camera when I bought it (used). Seems a nice enough lens - I scarcely use it though, as I am quite attached to fast lenses for available light. I've heard good things about the 55-250 - certainly more reach (one of my concerns), but not sure it is wide enough.
Any personal favorites I should look at? I'm probably not talking l-class glass here for a knockabout lens.
