Black and White Ruffed Lemur, MadagascarHere’s another of the many different lemur species I was able to photograph while in Madagascar back in May of 2007. My total count was 23 different species — this being the black and white ruffed lemur. Nikon D200 with Nikkor 17-35mm lens (at 35mm) ISO 400, f/4.5 at 1/100th of a second, two Nikon SB-600 flash units.
