Awesome detail! Im assuming thats a macro lens. For macro coral shots, do like the 60mm or the 100mm range on a crop body Gary? Are those shot through glass or acrylic? They look great!
Hammerhead, my primary lens for coral shots is a Sigma EX180 macro, with or without extension tubes. A 60 mm is too wide and I sold my 100mm macro several years ago to buy the 180, and never replaced it. I miss it sometimes.
