Yea... that's a new language to me... lol. I've always wanted to take a class or something on photography to learn how to adjust all that stuff, but never got the chance. I could care less about taking pics of the fishes, haha. Most look the same as the ones already online. I wonder how big the macro lense will make a difference on taking pictures of corals.
Macro lenses from my understanding give you a 1:1 ratio on your sensor. Check out "extension tubes". Kenko makes some decent ones because you can mix & match focal lengths. You can pick up a set on ebay used for about 80$ Extension tubes adjust your focal point away from your sensor for magnification. So instead of 1:1 you can get a 5:1. They are a nice option if you are not ready to spend $$$ on a macro. The shots I have on my build thread are with a 50mm and extension tubes. That should give you an idea how much it zooms.
