LOL....Thanks.......
Nope nothing special just your basic Nikon D40 and a realy nice 105mm Macro lens, heck the lens cost almost twice what the camera body cost. My camera kit cost me $495 thru amazon and from there I added the Macro lens.
Part of the secret is that I minimize all visual noise as much as possible, this is usually camera shake or vibration caused by pressing the shutter button, sounds silly but you can't begin to understand how many problems it causes when doing detail macro work. I can't stress enough how important a good tripod is! Also, use a shutter remote or the camera timer! All the pumps off and clean the glass on the inside of the tank right before the shot.
