Does anyone use a macro/micro lens to take photos of their fish and aquariums? I'm struggling to get the close up shots I want, and Nikon's auto settings aren't doing it for me. I have a Nikon D7000 paired with a Nikon AF-S VR Micro-NIKKOR 105mm f/2.8G IF-ED lens. What lens do you use and what are your go-to settings? Any advice for a photography newbie would be greatly appreciated!
