Hey everyone, I am thinking about buying this lens as a replacement for my kit lens that came with my Rebel XT. I have read alot of reviews and it seems tobe a verygood lens. My question is some people say this lens sucks in dust. How does it suck in dustand how much dust does it suck in. And do all people have this problem with this lens? Does the dust go in the lens or does it get sucked into the camera body? Either way i think this lens will be good for my main walk around lens. Right now i have the kit lens
EF-S 18-55 mm f/3.5-5.6 USM Standard Zoom Lensand i have the
EF 75-300 mm f/4 - 5.6 III Telephoto Zoom Lens. I like the 75-300 but the pictures aren't as clear as i would like them and the color doesn't seem to beverybold. Those of you you whohas this lens,will i see a noticable differance in the EF 28-135 f/3.5-5.6 IS USM standard zoom lens compaired to my other lenses?
