Wouldn't that be nice inside the camera? Likely, they're using an
acrylic adhesive tape. Maybe.

And your point is? Film based cameras used a neoprene foam light trap.

Methinks his point is that neoprene foam isn't electrical tape.

Nor did Rich prove that the Canon lightseal was electrical tape, it may
well be opaque mylar tape. I doubt either Rich or the guy who opened the
camera did an analysis of the black material.

Mike's point is likely that the material need not be exotic, complex or
expensive. Merely effective and easy to retrofit without changing over
time, humidity and temperature. For that matter, it doesn't necessarily
need an adhesive if the assembly locks it in place.

Rich looked at a photograph of the stuff. It looked like plastic. Hey,
it looked like cheap plastic electrical tape! Everyone knows that on
expensive quality cameras it's absolutely essential to use stuff that
looks expensive.

Some manufacturing tapes are extremely expensive.

He said "looks" expensive, not IS expensive! :-)

Canon should have welded 0.25" Tungsten Carbon Steel as the light baffle.

Some manufacturing tapes are extremely expensive.



The most expensive tapes are teflon re-inforced with a woven material,
like fiberglas or carbon fiber. Kapton tapes which are used in
electronics cost a lot too. You can also get pure metals with adhesive
backing for shielding. The two primary higher performance adhesives are
acrylic and silicone-based along with some very strong partially-curing
epoxies. Nikon has used kaptons to hold things like ferrite noise -
supressing rings in-place in cameras.
