My ama yesterday went well so I'm happy to talk about more stuff that I know about. While I can talk a decent amount about digital photography most of my experience is with film stuff. I have grown up in the digital era so I may not be as experienced as some of you older folks. I own a few soviet cameras, a chinese one and a couple old cannons. I've used a bit more than that so I should be able to answer a decent amount of your questions.
Oh no the lube in the Zorki would get fucked up too! Don't leave it in the car.
Well, is it any easier to relube? Canon slrs involve a million microscopic screws and springs and stuff and you risk damaging things every time.
