I just remembered there was a Macro thread so I decided to drop these pictures here as well (had them over in the d7100 section). I've been using a 105mm f2.8G lens with various combinations of Kenko extension tubes. For lighting I sometimes use a speedlight 910 with a soft box diffuser angled downward. Here are some critters I snapped today and last night around my house.
