Banzai Beach on the North Shore of Oahu, Hawaii, in the winter, is the best wave photography beach I have been to.
The beach is beautiful and the waves are huge with great shape (perfect for surfing). Like clouds, no two waves are the same. The challenge to capture just the right wave framed perfectly under the right light (many clouds this day) could content me for days.
The orientation of the waves to the beach (and the wind on this day) is great, but to get deep into the waves, I used a 700mm focal length. Taking advantage of the lighter weight of the 500 L II Lens, I was shooting handheld and rested on my knees - for hours. A drop-in circular polarizer filter was used.
