I suppose a 35 but right now I have an CV 40mm f1.4 sc and I almost never take it off the body. That single coating provides a little more contrast in sunny Florida.
FrankS said:50mm for me. If I back up far enough I can usually get most of what I want, and its long enough to use for a portrait lens if you're careful. It's also long enough to isolate details and be rid of distracting background elements that distract from the main idea/subject of the photo. Sometimes a 35 is perfect, but usually it's a 50 for me.
