I am interested in photographing a (legal) Falconry demonstration near Melbourne, Australia (Healsville Sanctary). I intend to use a F90X with a 80-200 f2.8. I understand that a longer lens may be necessary but I have been to the demonstration previously and know that the birds can fly very close to the audience. The 80-200 will be adequate for many instances. My question is what mode should I photograph in and what type of film should I use? I have thought of setting the F90X to shutter priority at 1/500s and use a fast (ISO 400 or above) negative film. I would also like to set the film transport to high and continous autofocus. Is this setup reasonable? I thought a negative film is warranted because of the potentially difficult lighting conditions. (I generally prefer colour reversal film). My other concern is whether the autofocus would keep up with release priority. Any other suggestions would be appreciated. Thanks. Eric
