At the moment I have EF-S 18-55mm USM lense on my 350d. I am thinking of getting a Canon EF-S 17-85mm IS but at around £330 for it, is it really worth it. Have any of you made the change and noticed a diference?
Yes
Downside..
Cost...
Size....
Becuase of the increased length, sometimes the flash casts a shadow if care is not taken. this probably appiles to all lenses longer than the kit lens
Advantage
everything else
Since swapping them round 4 months ago I have
never been tempted to put the kit lens back on
Put in perspective I certainly think its worth the money over the kit lens ( and I got mine for £410, then). Possibly the second best Canon non-L lens for non full frame sensors. There is still the 17-55 ( 2.8) IS

but at twice the cost
However if you are in no hurry, the kit lens is by no means "rubbish"
Its just that with better lenses ( esp
L) you can concentrate on getting the best pic possible without worriying about the lenses limitations
