nice photos. I was there last winter and saw 2 guys with what looked like 800 or 600mm lenses, and a guy with a 70-200 IS v2. Then near one of the eating areas i saw 3-4 teenage girls with what appeared to be a bunch of different vintage rangefinders. Nice zoo, and again, nice shots.

5D Mk III, Elan 7e, Nikon J1, some old rangefinders
