All noted. Yes, I still have the blade. I am calling Canon today and setting up a repair. Thanks for all the advice!

You say you noted a "plastic" blade. Shutter blades are not plastic, they are metal, usually some alloy/titanium/etc. So that plastic bit of crap you found on the sensor was something else. Maybe it fell off the mirror, maybe it came off the focus screen shims or whatever, but it is not from the shutter.

dacop, were you shooting video or shooting in live view mode? I didn't think a camera could function properly without a shutter blade unless it was in one of these two modes.

Aren't some high end models equipped with carbon fibre or kevlar shutter blades? maybe getting mixed up on that.

Here's a video of shutter blades in action:

Also, what does your closed shutter look like with MLU eneabled? You should easily be able to see if a blade is missing.

Its a Canon EOS-1D MarkiiN

Here is what this thing looks like. Maybe you are right, maybe this is some sort of flange or shim that fell off?







Question, wouldn't I be able to tell if all the shutter blades are there and indeed this is just a flange/shim by lifting up the mirror and seeing if the sensor is covered by these blades?

That's a shutter blade. Your second pic is of the first shutter curtain, so the missing blade must be from the second curtain, which can't be seen by lifting the mirror.

I've gotta say, I'm amazed that you were able to get more shots after the failure...

Especially shots in which you couldn't tell there was a shutter blade missing.

Thanks again for everyone's input. I wanted to make sure it was a shutter blade, I am shipping the camera to Canon today.

I was very surprised myself that I was able to continue and not see any difference in the images.

I guess it depends on what part of the shutter it is , as noted its likely to be the 2nd curtain . and maybe if the leading edge of the 2nd curtain is still there you are not going to see a change in expossure. maybe different shutter speeds would show more over expossure on part of the frame.

Anyway its a moot point as using it any more risks the whole thing crapping out on you and wrecking the sensor , or the filter on the front (but to canon thats one and the same thing.)
If that happens its basicly a write off as a sensor fix on a mk2n would be alot ore than the cost of a good mk2n.

If you have a good 1D2n, that seems a worthwhile price to bring it "near new". Is that the discounted price for CPS Gold?

Not discounted.


Question, does Canon clear the actuation after they replace the shutter?

Don't think they do usually. Maybe if they replace the mirror box and other bits.

It may just be the repair place over here though. I just bought a used one from a new 'tog . He had had most of the internals replace in july (from what he described it was a pretty major rebuild) . He used it a few times since but he had used his pair of mk3's most of the time. I checked the shutter count and it reported 170k .


Maybe he put that many on it , although I very much doubt it. After all his name was not Hammy

It's always a gamble on these things with shutters. You could pick up a body thats had almost no use and the shutter could go tomorrow while you could have one that goes way over the 250k barrier without a problem.

Mine had about 200K before it went. I got it back today, so far so good. But all my settings were wiped out. Everything is at factory default.

You guys do know how robust cameras are right? A shutter blade won't EVER knock out your mirror (what the hell are you smoking) and not even touch the AF sensor. Probably wouldn't scratch the sensor either, that thing is tough.

But HOLY CRAP YOU PULLED OUT A SHUTTER BLADE WHAT.

I was using a little artistic license, AKA hyperbole...with a Shillelagh for added emphasis.

And, I don't smoke.
