I have had my Canon Rebel XT for over 6 months now and the kit lens just isn’t doing it for me anymore. I think the new Canon EF 24-105mm f/4 L IS USM Lens is gonna be the next one for me. The cost of L glass is expensive, but I see the results from it everyday at work and the results are fantastic. The added IS will make a dramatic difference in my ability to hand hold shots. I am getting tired of blurry images when taking anything inside. The 24-105 should be a great walking around lens. The photographer I work with has the 70-200mm L glass lens and that thing is a beast. We have a few other non-L glass lenses and the difference in the quality is huge.
