This is a great thread.
I get smirks, mostly, from acquaintances when I photograph with my Canon F-1N. They're using either compact digital cameras (without viewfinder -- extending their arms to see through their LCD screens -- looks funny), or the over-sized DSLRs with huge lenses. I'm a novelty; they'll comment that they didn't know anyone still used film ("How quaint", or "Get with the times"...). Funny, how some of them often complain about out-of-focus/blurry images, "noise", color correction problems (lack of technical practice).
Just this past weekend, my wife and I were visiting our older daughter at Scout camp. At one point, a boy next to me observed that I had an "old-fashioned" camera (F-1 with 35/f2 lens).
"Is that the kind that uses film?"
"Yes."
"Cool."
"Would you like to hold it?"
"OK... Hey it's heavy... Wow, it looks cool through there."
Possible convert?
I recently acquired an 4x5 F/Arca-Swiss (rented a 210 lens, as I can't afford one, yet). Setting it up in a local park attracted some attention. One person, nearby, came up to me and asked what I was doing. When I explained, she was taken aback that this beautiful instrument was a camera. When I showed her the film holder(s), she couldn't conceive of the size the final image would make, one at a time. I explained that there were various sizes even much larger. I let her look through the ground glass, and it was obvious she was pleasantly surprised of discovering something new (to her).
