How weather resistant is the Nikon D750?

Particularly to dust and moisture. This is kinda a follow up question to a previous question.

Heavy rain is fine for a bit, but if you submerge it… You'll need a new one. Salt water will wreck it even more. Against dust, make sure your lens is sealed as well.

All DSLRs are resistant to dust, as long as you keep the lens or a body cap attached. If they weren't then you wouldn't be able to use them.

All DLSRs will survive some moisture in the atmosphere, like fog or mist, or a few spots of light rain. A weather sealed camera will survive heavier rain but only if you also use weather sealed lenses on your weather sealed camera body.

None of them will survive a dunk in water.

It is water and dust resistant. How resistant? Hard to say. I would expect it to take a little rain and a bit of a dust storm. But, can't dunk it in water. And if you operate it in a raging dust storm, I would be surprised if it survived it.

I would say that the D750 has no weather proofing. If it gets any rain or mist on it you might as well kiss it goodbye
