I broke the bank and purchased the 7D and 70-200f2.8 IS II.
I knew we could use the 70-200f2.8 for years to come as my 6yr old loves to play baseball and was just selected to the All-Stars team. My 13yr old daughter is a dancer and her recitals are very low-light and they do not allow flash. I kept going back and forth between the 700-200 f4 and 70-200 f2.8 but i figured the 2.8 lense would be more beneficial with the sports and the dance recitals. Now I need to choose a good walk around lens. Please give me some recommendations for a good walk around lens. I have seen good reviews on the 17-55 f2.8 IS. I would like to keep both of the lenses in 2.8 if at all possible.
