The camera Brie Larson's Weaver character uses is a Leica KE-7A M4, with a little flash unit on the hotshoe. Being a Leica, and a rarer one, that's got a hell of a price tag attached to it (if you can find one of course)!
Thanks @ianchristie1972 I wondered what the other thing was!
I dread to think how much all that costs...
I like that the description right up front says "As seen in Kong!" as if that justifies the price for an obsolete camera. Clearly trying to pander to us prop nuts rather than those of us that enjoy photography as a hobby/profession.
