Awesome shot! I have been looking at macro lenses and have a few questions. Are you using the tamron 90mm macro lens for this picture? Do you take the picture using a tripod? How far is the camera lens from the coral?
The acros in my frag tank are close to the surface and I dont have any lenses that allow me to take a top down picture with a topdown viewer, the corals are too close to focus on.
