Hi Eric...thanks for your response.
Let me try to be more specific.....Iamlooking for agood quality walk around lens, primarily for"portrait" meaning group and individual (not in a studio/professional environment). "Kids" meaning action and sports. "Indoors" meaning family gatherings, events, anything. "Travel" meaning landscapes, wildlife.
I think my best choices are the 17-85 IS or the 24-105 L IS? Do you think the latter,despite the price, would be a good choice for what I want? And, do you think I would miss the difference between 17mm and 24mm?
Hope I am a bit more clear....thank you again!!!
