We had 2 hurricanes off shore this week of shore near Long Island. We had big waves (for Long Island) So I took my sony FS700 and Sigma 200 to 500 MM F2.8 lens to the beach. For most slow motion of people the 20 FPS that I got from the sony was great. Now the lens!!!! I took out this huge and awesome Sigma lens. I put on the 2X extender so I was shooting 400 to 1000 so I could shoot surfers a quarter of a mile away. I will add more surfing clips from my day at Long Beach soon. Enjoy
