I will be ordering a new body and a couple of lenses in the near future. I am interested in wildlife, candid street, portraits, and event photography. In a dream world I would buy the correct lenses for each spaning a range from 10mm to 400 but, alas I am not rich. I will be ordering a 7D, EF-s 17-55 f/2.8 and I think a 70-200 f/4 IS with a 1.4 extender. Figure this should hold me over until I can manage a 100-400. Just wondering if any of you have used the 70-200 with the extender and what kind of results you got. I could just get the 100-400 but then there is that gap from 55 to 100. Or is that such a big deal? Any advice/info would be great.
