Love these forums, but everytime I come here I find a new lens that I want to buy. I was just looking through a great thread
about lenses to take to Disney World as we have a trip coming up in November and the 17-55 is looking like a great upgrade and choice for the trip.
At least convince me it's a real pain in the ass to sell a well-taken care of lens or something.
For travel, Disney, snap shots, I think think 17-85IS will be a better choice, mainly because of its size, weight, range and flare-resistence. You can use this lens without a hood.
The 17-55IS's main advantage is F2.8 and low distortion. I would say the IQ improvement is secondary. It is good, but 17-85IS is not bad either.
The main disadvantage of 17-55IS here is its flare issue, although it is not as bad as the rumor suggest, it is there. You really need to use the hood with it, and it makes this combo huge compare to 17-85IS.
The 17-85 is just a lot more convinient for your case.
