I don't usually use telephoto lenses when doing street photography. It's kind of strange to walk around, especially at night, with a long 200mm lens, it's not easy to conceal, and people tend to take notice. That said, I really like how this photo turned out. It was pure luck that the guy on the left stopped to light his cigarette. The lighter's flame illuminated his face at just the right moment and still within the plane of focus.
