Borrowed a friends Sigma 105mm Macro lens and Canon T2i, and got a couple good shots with it. Tank is lit with LEDs, so I'm very pleased with how these turned out. I shot in RAW and then edited them to get as close to the actual colors as I could (on my monitor anyways). I'm at ISO 100 I believe, Fstop of 1/15 as well. I'm using the Tv setting as well. Critiques are more than welcome, as I'm new to the macro game! :tongue:
