I bought this lens a few years ago to go with my EOS 30 to replace my kit lenses. I though this would make a nice allround lens and it was not too expensive either.
I have hardly used it. Its reaction speed to my camera is extremely slow and focusing is tiresome. The zoom ring is very heavy going indeed, making it useless for fast moving objects coming towards you or away from you.
I have replaced it with two separate lenses now and it lives in its box in the cupboard. It will probably be up at Ebay at some point.
