I use a Nikon D5100 with a 200mm f/4 micro lens, mounted on a tripod and with a remote control so I don't shake the camera. Aperture is normally around f/10 "“ f/20, if I can't get the subject to sit still I crank up the ISO settings until shutter speed is acceptable. For lighting I use my aquarium lights with 30% blue 3W leds and 70% whites (14.000k).
