I thought the ignition temperature of magnesium was very, very high?

Edit: 630°c. I was confusing it with it's burning temperature, 3600°c. That's why it's used to light thermite.

I believe camera bodies are a magnesium alloy too.

Yeah, it isn't that hard to ignite. I did it with an ordinary cooking torch. Magnesium is what's used in sparklers though, so it can definitely be ignited with much less, albeit in significantly smaller particles

They typically are. I doubt the camera manufacturers do burn tests on their cameras though, so we don't know if they're more or less flammable.

That would be fun to test though. Anyone know where I can get a random chunk of camera to set fire to?

Yeah that's what i meant, they'd probably be less flamable I think.

Ask DMP if he has any pro bodies that are broken beyond repair.

Looking through older camera models, It looks like Magnesium is a fairly recent development (2000 for canon, 1996 for nikon). Doesn't bode well for me finding an ultra-cheap one to "experiment" on.

Yes I do actually. I sanded the paint off a D2H once, then I realized I was making magnesium powder and realized that was a bad thing, so I kept on going. Sold it to a friend still somehow... Not gonna burn it though.

And the 1Dx is the most awkward looking camera ever. So ugly it just downright turns me off. And I wish it cost more in line with the D3s when it was introduced. BECAUSE ITS BASICALLY A CANON D3S.

Why is it so big? If I had one, I'd probably end up never using it because of the size/weight. The only time I really use my E-410 is when carrying around medium/large format gear is impractical. This thing is so big that I might as well just use the 645.
