Haha. USM dun cost alot isn't it? Yeah probably they prefer an all rounder lens like the 18-200. But i can see the the image quality from the 55-250mm IS is great.
not sure how much USM add to the price, but it does cost more than normal lens

ahaha. what is USM? 800 so cheap sure or not..but then mount plastic =_+
ultrasonic motor, faster and quite autofocusing, dun worry too much about the plastic mount since the lens is light, and the built is pretty good. personally tested it out so it's a good lens for that kind of price, and having IS helps a lot with that kind of zoom range.
but you do lost the wide end if u use this lens though since it start at 55mm
