On film when I said I still used 35mm - "Wow, I haven't seen that in ages...it's so ANTIQUE". :bang:
"Why can't your lens zoom?"
Some guest at work when I was just documenting a class passes on a message to my colleague to pass onto me:
"Tell her that she can use my photos if she wants to."
On a wedding at work, again, shooting for internal use:
"Excuse me, but who are you? I'm the PROFESSIONAL photographer, sorry if I get in your way."
and when I had a small point and shoot for a relative's birthday and my uncle brings in his bling DSLR kit and I say I don't need a big camera:
"at least I earn a lot of money [from shooting with my kit]"
I must look really dumb or something for people to think those thoughts about my skills and such. :'(
