Hahaha glad we all have a sense of humor. I could care less if it is loud to me, I just don't want to be too distracting too my subjects. I think in the "ideal" street scenario where there are lots of people and ambient noise it won't be a problem at all. However, when I encounter someone alone then it becomes awkward or uncomfortable (for us both).
I still have a lot of things to learn about street photography and building up my confidence is definitely one of them.
Thanks for the tips guys, I had forgotten about the RT, that should be a pretty quiet camera!
