Amazing shot, from indoors at the Universeum, the indoor zoological complex, indoors in Gothenburg, Sweden. I used my K-5, and my wife's Pentax FA77. In the picture you can see my wife's hand, her DA50-135/2,8 (the best zoom lens I've ever come across), and her K-5, which all thrived in the heat, and humidity, being sealed!
The monkeys roam around freely, but this one took a liking to my wife's eye visible in the other end of the camera lens ;-)!
