No pass needed.. I felt there were tons of great places for great shots with out a pass.. some corners I had too much lens (200mm) and some I felt 400 mm would do the trick.. I would like to have next time a 1.4 tele with me but I did ok for just having the 200.. it helps having the 2.8 200mm and a d300.. I had to bump up the iso with the tree cover and dark clouds out most of the day and my old d40x would have made alot of noise with the iso numbers I was pushing with the d300.
