1/1000s, f/1.4, ISO 800, 35mm
The 35mm f/1.4 is just a stellar performer in low light. Here's a shot on a 5d Mark II at 1/1000s, an ISO of 800 and the lens wide open. This being a well-lit street in Hong Kong, I could easily have gone with a lower ISO, but it just didn't occur to me (and besides the 5d Mark II does pretty well at ISO 800).
Overall, the lens still strikes me as a little too wide for my type of street photography. Still, it has an amazing ability to turn a lot of eyesores into objects of art.
