Two MORE problems with plastic-bodied cameras

They attract dust FAR more readily (owing no doubt to static build-up)
than metal bodied cameras and in the sun, black plastic bodies heat up
hotter and faster than metal bodies, even those painted black. The IR
signature of a black painted magnesium camera is far brighter than
black plastic cameras. Use an IR camera with a strong IR source (the
sun) on a metal camera (black) and it can look purple owing to IR
reflectivity. The plastic affinity for dust was confirmed by a friend
with a D80 and D200. He reports that the D80 attracts more dust and
although he's had both and used the D200 more, it has not needed
sensor cleaning at all in six months, whereas the D80 has on a few
occassions.

 

Do us all a favor and *STFU*.

 

Oh, yeah, no doubt. As long as you're going to make it up as you go,
please continue....

I think if you'd test that claim before you shared it you would find
the conductive properties of most metals is much higher than that of
most plastics, which causes most metals to heat up more quickly and
more thoroughly than most plastics.

Which would mean the magnesium camera is hotter than the plastic
camera. The signature for the plastic signature could be misleading
because plastic is a good insulator ... so the "heat" may only be
external.

The amount of *reflected* IR is due to the IR absorption properties of
the material. The radiated IR, OTOH, is heat.

Radiate =/ Reflected

Would this be the same "friend" who took this gawd-awful photo? If so,
dust is the least of his worries.

Haven't you got a gay wedding to photography somewhere?

 

Have done it, using a Ratheon IR sensitive thermometer. However, I
realized this when I was using an E-1 (metal) and an E-330 (plastic).
The plastic got noticeably hotting in a shorter timeframe.

Only a piece of the original file, which I stated before.

 

How much more proof than one friends report would anyone want.

I hope Randall does a nice job on your wedding.

And get a dictionary while you're at it...

 

BS SNIPPED ...

^^^^^^^^^

You want us to believe that statement?

 

Do you believe *any* of Rander's statements?

TR

 

Sure. It's his only friend, his right-hand man.

 

The big problem with plastic bodied cameras is that they don't leave
as much of a dent in Richies head as the metal ones.

Doc

 

You don't think anyone takes you seriously, do you?

 

Perhaps the best argument for metal bodied cameras ever presented
here.

 

So you measured the heat reflected from the camera rather than the
heat transmitted into the camera. Well done.

 

Black body radiation is a two way deal.

 

These thermometers are nasty inaccurate when used on metal.

 

That can be done as well.

 

Only if it's raw metal, not painted.

What kind of a rejoinder is that, "Not Disclosed"? Some sort of self-parody?
