What shutter in the 10D?

[vvizard]

How does the shutter-mecanism in the 10D work? I think I've seen Curtains and lammels used interchangeable in the manuals. I think I've read a bit about this in the 550EX manual which I had as a PDF (don't know how I got it). Anybody who could point me to a paper which explains (hopefully with pictures) how the shutter-mecanism work? I really don't fancy taking this baby apart =)

I would strongly advise against trying to disassemble the camera.

The Canon 10D has a Electronically-controlled focal-plane shutter. It's electro-magnetically operated. The shutter "curtains" are actually a pair of multiple blade curtains that travel vertically when the shutter fires. I believe the blades are metal or a metal composite. I base this on the fact that the blades in the EOS 1D are made from carbon fiber and "super-duralumin", their word, not mine, so I'd assume that the 10D blades are similar material.

The shutters are virtually identical to their film camera counterparts. Any web site that has illustrations of a multi blade vertical shutter will give you a pretty good idea of how it works. IF you really want to you could buy an old EOS film camera and disect it.

I hope this answers your questions. If you have more let me know.

Wow, the micro-tools PDF-file was amazing, now I don't have to kill my 10D to see what's inside :)
