Yes, I think it's a combination of factors, but a TLR seems to generally be viewed as benign by the public. (Why
is that man staring at his belt buckle?) And when I have gotten comments on my Yashica 124G they've been positive and reflected interest. The last such occasion was just a couple of weeks back at a fiddle festival, taking some shots at jam sessions. A maybe 40-ish woman with an elderly gentleman in tow said "My -- that's an interesting camera." (At least she recognzed it as a camera.)
So I turned and showed it to her, explained what it was, and got the Standard Question #2 -- "Can you still get film for that?" I explained that running into the nearby CVS and grabbing a roll was unlikely, but online orders get me what I need in 2 days. Mentioned I was retired and do my own processing, exhibit in shows, etc. and the guy (her dad) showed a smile, I imagine he appreciated the retired part!
(Now the EOS xxx sporting an original EF 24-70 f/2.8 with the deep lens hood gets about the same reaction as a grenade launcher!
