I feel a self awareness about using my mf and lf kits, but not self conscious in a negative way. Because I almost always use a tripod, there's not much I can do to be invisible, so I've learned to somewhat enjoy the attention it gets. I've never been scoffed at, or looked down on, rather just the opposite. People will not infrequently make a comment to the effect that "what you're doing is 'real' photography." If it leads to conversation, so much the better. I like and admire digicams, but don't use one, so I am certainly not sending out a snobby vibe, and find the engagement interesting.
