I took these photos of surfers on the windward side of the island while making the drive to Hana. These were taken at a popular surfing beach near Pa'ia (pronounced pah-ee-a) which is the last town you see before Hana about 40 miles away.
These were all taken with the Sigma 150-500mm at 500mm and hand held. Sorry Q, next time I will have the tripod.
I have been looking at a new lens to buy before my next trip to Hawaii. Sigma makes a 300-800mm f5.6 lens that I think I'm going to invest in. You'll know why when I put up some more of my ocean shots. Is the suspense killing you? LOL
