I am new to photography and being a surfer myself, I really like to take pictures of surfing. Some of the areas I travel are RI, Florida, California, and of course the North Shore of Oahu. I will be heading back down to Oahu in late November to catch some triple crown action. Right now I have a 40D with an EF 75-300 zoom lense. I know its not the greatest lense so I was wanting to know what lenses everyone else uses?
