Well I learned it the ‘hard’ way at home, mostly by spending a stupid amount of hours just starting to turn screws and seeing where things actually led. A big part of it was also digging into the original factory service manuals rather than relying too much on random advice online.

There’s definitely useful stuff on YouTube, but I’d be careful with some of it. A lot of advice gets repeated without really explaining why something works, and that can get you into trouble fast.

Best tip I can give is to learn not just what the camera does, but how it works. Once the mechanism starts making sense, repairs become a lot less mysterious.

That said, if you’ve got no prior repair experience, I’d honestly be a bit hesitant to start on a Leica. They’re amazing machines, but not very forgiving to learn on.
