i shoot with a range of cameras (all canon).
so far i've shot with the Rebel XT, 20D, and the 1D Mark II, as well as a smorgasbord of lenses; 28-90mm, 35-135mm (old lens), 70-300mm (crappy black one), 70-200mm L series, 35mm wide angle, and the 45mm and 90mm tilt-shift lenses.
the Mark II and 70-200mm L series is by far the most prime setup that i've worked with.
