I'm travelling to Maui, I've never shot kitesurfers at Kanaha Maui and I was wondering what lens do I require? I have a Sony 70-200 f2.8 gm II but I'm concerned that it might not have the reach even if I did video editing to bring the riders closer. Also do I have to bring along my own tripod for this trip? I looked on the internet and there doesn't appear to be a place where I can rent one in Maui. Thanks for the help.
