This is the first time that I saw the ocean do this as well. Just shows the great difference in temperature between the water and the air. This happened only once though so I must think of myself lucky here. Nex-7 and the CV 15 f4.5 delivered again. This is proving to be a great combination, you just have to use Cornerfix with the images to get rid of the magenta cast. Only a couple of seconds more work in processing, that's all. Well worth it in my opinion.
