Finning technique, taught by a shrimp goby

Today I did 3 dives, 2 with the Sigma 17-70mm (which i’ll write something on in the future) and then the last one with the Zeiss Milvus 50mm Macro lens, which is manual focus. The 50mm lens is the lens that I used for the Shrimpgoby in the video below, shooting at a higher than usual frame rate of 300 frames per second. ┬áSo this is being played back at less than 1/10th of real time speed to show the detail in the finning method of the goby.
