I've had my camera (Rebel XT) for almost a year, and I've been using the lens that came in a kit with it. About time to upgrade! Since I've never bought a lens before, I'm a little lost. Finally narrowing it down to two lenses, I'm not sure which would be better to get. I do want to keep the wider angle if possible, but I also want a substantial amount of zoom.
Are these two lenses the ones I should be looking at?
Tamron 18-200
Tamron 28-300
Any help is appreciated!
