In order to get good zooms while at concerts? I usually don't attend the largest concerts - so I don't need a lens that will zoom up 400 miles - but then again, I rarely ever get "front row seating" (or standing, in this instance).
I also plan on using my lens for portraits, so I will most likely need a lens that varies in terms of how far/close it'll zoom in and out (because, from what I know, portraits are typically shot fairly close up, while concerts are normally [for me, at least] shot from a pretty far distance).
Anyway, what lens(es) would you suggest for these purposes?
