I found this male and female doing a bit of grooming just outside of the jungles of Cambodia. I've taken photos of a lot of monkeys. They are all over SE Asia and India, so I always pay special attention to them. I suppose that, as a Westerner, I'm just used to seeing monkeys in zoos. So whenever I see them running all over creation, it always makes me laugh. I chase 'em around and take photos like a nut. These two, however, I snuck up on. It's not easy to sneak up on a monkey, mind you. But these two were really into each other. I did a low approach like a Navy SEAL to get as close as I could. The female noticed me at the last second, and I grabbed this shot before they started to run away.
This was shot at 70mm, which was maximum zoom for my 28-70mm lens. The f-stop was at 2.8, which allows me as much light as possible in a tight focus plane. I kept the ISO at 100 for a clean shot with no noise. There was enough light for a quick shutter speed of 1/250.
