A sensor is not a camera.
A camera is not a sensor.

Get a clue.

Still there are film cameras whose size is a fraction of the size of
current full frame DSLRs. It should not be a problem to make very
compact full frame DSLRs. The electronics can't take so much space, as
the Sony NEX cameras demonstrate it.


Alfred, are you and Rich cousins?

They still make film for the Minox?


Nikon FE is an example of a small FX film camera, or Olympus (forget the
model). For digital, I think the AF system requires quite a bit of space
at the side(s?) of the mirror box, the rear LCD adds thickness on top of
the sensor and even the sensor is thicker than film. The batteries are
big and heavy, the flash is bulky... if you were willing to forego all
that, it should be possible. Mirrorless APS is probably the closest
thing today, or micro 4/3 if you don't need a real viewfinder or high
ISO performance. The Hasselblad design could probably be adapted to 35mm
but that would handle like a mini hand held slide viewer: a longish
spice-box, maybe with a folding pop-up viewfinder so it's not
top-viewing - hold it as if looking through a toilet paper tube.

I was mixed up about that; I was thinking of the old style which is
already flip-up and top-viewing but a more complex system could relay it
to the rear for normal viewing and end up kind of like the new digital
models. I'm really not familiar & shoulda kept my trap shut but there is
probably a way to devise a folding system which would result in a
compact 2" cube sized body, probably an inch or more longer in the
viewing axis to hold a battery and LCD screen. AF could be a problem.

I am never impressed by ignorant fools who think that even though they
have no experience or training, they still believe themselves to be
smarter than engineers with gradaute degrees and decades of experience
designing cameras.

Know anybody like that?

Perhaps the poster (Molon) has hands the size of those on a shrunken
Barbie doll. Does he not understand that for most shots cameras are
hand-held and the "shutter" release is pushed by a normal-size human
finger. This sort of logic is one of many examples of why I see his
posts only when quoted by others.

Go ahead and keep talking nonsense. The reality is that compact cameras
dominate the market. Size matters.
