Hello all, I have a photo shoot lined up end of May for the Shallowsport Owners Tournament in Port Isabel TX. Part of that will include shooting from a helicopter to capture the early morning shotgun start for approximately 160 boats. I have never shot aerials in fixed wing or rotary aircraft. My longest lens is a 200/f2 so I may be somewhat limited for telephoto work. Does anyone have any tips for getting good images shooting from a helicopter which is inherently very rough as far as vibration. I am concerned about being able to get good clean focus in these conditions. I will be using my gitzo tripod with markins ballhead or the RRS monopod whichever proves to work out better for available space. I sure don't want to end up with a bunch of images that are poor quality due to out of focus or other problems I don't know about yet. It would be really great to get some good shots from this event, especially the aerial part of the shoot. Any tips appreciated.
