They typically sound like Jack In The Boxes with the squeek squeek squeek tic tic tick sonds. Sometimes it;'s almost embarrasing but then the old timers come up n have plenty of stories about their TLR cameras when they were youngsters.
What bugs me, I do really enjoy it, is the almost inaudable zit the shutter makes when you fire it. It is such an unsecure sound after playing with monster cameras like the RB that remind you a piece of film has been burnt, like etchings in stone. Makes me feel like I never actually took a picture. zit, that's it.
enjoy it, don't ask anymore questions, just post pictures instead. You will have so much fun with that camera.
