A mandrill in a zoo. As Wikipedia notes, "[t]he mandrill (Mandrillus sphinx) is a primate of the Old World monkey (Cercopithecidae) family, closely related to the baboons and even more closely to the drill". Nikon D3100
Thanks! I used a Nikkor 55-300mm DX VR. It's not the best lens out there, but I got it for $100 off and the VR works very well. For this shot, I'm wide open at f/5.6 so the quality isn't the best (noticeably at 100%), and I increased the contrast and vibrance significantly.
