Ring-Tailed Lemur, Southern MadagascarLooking forward to someday returning to Madagascar. Ring-tailed lemurs were the first of the 23 three species of lemur I ended up photographing on my three-week trip back in 2007. Nikon D200 with Nikkor 80-200mm lens (at 175mm) ISO 100, f/2.8 at 1/1250th of a second.
