Also a good idea to develop the habit of holding the camera pointing down (lens down) while changing lenses. That way, you have less risk of some bit of dust/sand/whatever from falling into the camera while it's open. Let gravity help you keep your camera clean.

Likewise (except for the Nikon bit). I do a lot of shooting in the California desert, which is about as rough a test as you could ask for for lightproofness---I have yet to find a leaky shutter on a reasonably modern camera. I think it's mostly a theoretical problem, but I'm sure someone will now turn up who's had the opposite experience.

Yes you can. You don't even need to change the lens under subdued light. The thing is light tight. Remember, your lens lets in light too---else you can't even use the optical viewfinder.

Copal Square shutters (largely used in Cosina cameras) are notorious light leakers. In SLR models that's also blocked by the mirror, so not a big problem, but some early rangefinders using that shutter did have problems.
IIRC, C/V rangefndrs have a double shutter (or an extra shutter blind) to solve that problem.

Though with the lens on, most of the light is diverted to the viewfinder.
With the lens off, there is more of a possibility of light sneaking around edges...
Still not a good idea to leave the camera sitting around in bright light with the lens off (depends on specific models of course), also for the stated cleanliness reasons.

And Nikkormat/Nikomat, Ricoh Singlex/TLS/etc., Konica T series, among others.
I do use a digital device in my photographic pursuits when necessary.
When someone rags on me for using film, I use a middle digit, upraised.
