Hell I'm at shows shooting with Manual focus lenses frequently i get odd looks all the time. At the bigger events (like the outdoor shows at NXNE) I will end up beside older guys from the big newspapers. they don't look at me odd because they have shot shows with MF, instead they will ask to try my kit lol
I only get the snide stuff from young kids who aren't overly informed and think the only way to shoot is machine gunning with a big white lens
one guy i see regularly at shows here is even older than me
(I'm 51) and he shoots with 2 LX's and 4 primes all on film he develops himself (colour and b/w) I like it when he shows up because we will swap lenses and try the other guys stuff (he has some really nice glass)
