Lens suggestions for good coral shots?

Yeah that's a good point. Although I find with only 150W of light my shots aren't super sharp and I need to use ISO 1600 or higher. I use the large image to allow me to size down and increase the quality and decrease the graininess of the shot. I know my own shots wouldn't look too sharp with any aggressive cropping but it's a good idea if you don't have money for a macro. I wish I did but I'll be back to using my 18-70mm stock lens for a while.
