I used my 35 on the crop a lot in Lao, at the markets and at gatherings of friends where the action was up close, and people who didn't mind being photographed. It would be a bit short for portraits of strangers, I think you'd get lots of pics with that 'what are you looking at!' look.
My loitering - looking at buildings tactic with my 135 meant that I got several shots (accidentally) of people picking their noses in Nepal, that's how unaware of my intentions they were. This man just woudn't stop once he got going!
I would agree that the 135L would be far less confrontational that the 35L when taking candid street pics.
Most of my people shots that i take at the parties generally see me around the 17-24 range as im aiming to get 3/4 body shots. Having the flexibility in focal range is important to me in this situation. Out in the open i guess people are not as willing to pose for the camera.
Looks like this guy has half his finger up there!!!
