When I shot large format on the steet, I'd get lots of looks, comments and people coming up to talk to me. It came with the territory -how can you expect NOT to be approached when you got a huge tripod, camera with bellows, dark cloth....best comment I got was, "when is the gun powder flash gonna go off?".
When I was in NYC, I got a lot of people scoping me out and then coming up to ask "is that a Leica?" and then want to talk about gear. I don't like to, especially when I'm around shooting photos and trying to get a feel for the scene and remain anonymous. It got to the point where I would just make eye contact, say "yeah", turn and walk away. I just don't have patience to have the same meaningless conversations over and over again about a specific brand of equipment. I have some friends that are photographers and I can count the number of times on one hand that we had a gear-head conversation. Some shoot film, some shoot digital and none of us really care what the other is shooting and we display photos together and talk about PHOTOGRAPHY.
