Yurgen - Hmmm, you must have gotten close to get that with a 200mm... Perhaps you shot it with a digital camera where you get a zoom effect from normal lenses? Either that or maybe you were up to your waist in water.

Try some shots at a wider aperature though.. I think they'd highlight the surfer better. But you might get a number of misses. might be better to try manual focus than auto.
