To get back on topic, if I were made fun of/given grief for using my analogue camera, I'd be inclined to say something like "well, I don't like your shirt/haircut/car/nose (or whatever was appropriate), but I was taught to be polite and keep my opinions to myself!"

I confess I said something similar to someone who said to me "only retards still use Blackberry phones", when he saw me using mine. (Haven't seen him since!)

(Reminds me of the story of Winston Churchill, who, when rudely and publically scolded by a lady "Mr Churchill, you are drunk!", replied, "and you, Madam, are ugly, but I shall be sober in the morning....". )

Happy days!
