good luck sucker.
oh I see, so I have to stand miles away from the track, leaving the gap open to wretched spectators!
I rapidly change from 70-200 a lot when out shooting. And it's inconvenient for me to carry tons of lenses when I have a small backpack for motorbiking. So other than my Sigma 70-300/4.0-5.6 APO DG Macro lens, there's not really any options unless I spend thousands of pounds. :-\
