The heat doesn't seem to have bothered the camera. I added the
vignette only because the background is a little blah.

I am glad someone asked. The battery was low, so it's charging now.

Plastic bodied cameras are ok with heat as long as they aren't in direct sunlight. Then they heat up like ovens. However, worst case, noise goes up a bit.

They are no worse in this respect than any other black-bodied camera.

They are worse. They heat up more and retain the heat longer.

Metal would retain heat longer than plastic.

The correct scientific term for his logic is: "lasso thermodynamics" ;-)

No, metal sheds heat faster. How many plastic heat sinks do you see on CPU's?


Have it your own way.... I give up.

He does have a point there. Same with automobile radiators: If it were
possible, the manufacturers would go to lightweight plastic for everything
(like bumpers, etc) for mileage improvement. But radiators do best with
metal fins, not petroleum-based materials. My .02...

Only by chance!

Specific heat is generally given by mass. But since plastics are
generally less dense than metals one would have to compare by volume in
the context of metal v. plastic cameras. "dense" plastics have heat
density of around 1.7 j/gK wheras metals are closer to 1. Magnesium's
density is about 1.75 g cm^-3 whereas polycarb is about 1.2 g cm^-3.

In the end, close to a wash.

I'd expect, however, when taken out of sunlight for the metal camera to
cool quicker because of the better conductivity (heat) of metal.

It's germane to note than in home air exchangers the heat exchanger is
made of plastic for many reasons. (Economy in material and
manufacturing, very thin walls (conductivity), resistance to corrosion,
etc.)

They will retain heat longer but only because of thermal resistance.
Other than that little difference.

We are not talking about transient heating but a situation where the
temperature of the camera comes into equilibrium. The temperature of
the camera will eventually be that of the inside of the car unless the
camera is in the sun, in which case solar absorbtion and later
reradiation will have to be taken into account. The color and the
suface finish is the primary factor as far as radiation is concerned.
It doesn't matter whether the camera is made of metal or plastic. It
will get at least as hot as the inside of the car.

will get at least as hot as the inside of the car.

a) It does matter because the plastic is thermally resistant (compared
to metal), so even as it blackbody's away heat, that occurs at the
surface. Heat inside the camera will have a slower go of reaching the
surface to be radiated away.

b) Rich brought up the direct sunlight case.
