What's wrong with my 1DS?

I call it Mirror Pre-Lock but I think that's the same =)

Since I have only one IS lens and I said that it happens with all
lenses, I think the IS point is moot.

My truck cost $36,000 when I bought it and its been back to the shop 4 times in less then 25,000 miles.

Sorry I can be of no more help.

(I must have missed the part where you said you used it)

I've personally contacted all past and present forum members, (except fun-nowhere, ...formal attire - no diapers ;-), for a think-tank session.

We have figured out what is wrong with the camera.

It is "something".

This means you may be in a sort of warranty-limbo.

If it was "nothing", ...there would be no problem, of course.

If it was "anything", Canon would fix it under warranty, as in "anything wrong with a factory-fresh 1Ds will of course be repaired at Canon's expense".

Ahh, but "something"? Now there's a situation which allows Canon some wiggle-room.

Best be ringing-up your barristers :-)

=) This is a pre-production unit, and so I can understand that
there is something fatally wrong with it. As an engineer, I would
like to know what people think can cause this problem: The camera
has double vision. The test shot was taken with a tripod, cable
release, 10s exposure at f8 and ISO 100 with 28-70L lens. The
problem is clearly visible on all images, with any lens, any ISO
speed, and also with raw images:

I borrowed it from my employer over the TG weekend and let's say
that I was quite surprised when I downloaded the first images. Had
to use my good old trusted D60 for the rest of the trip...

Going through all of the messages in this thread to date, we seem to have eliminated these possibilities:
  • Shake due to mirror vibration (would only show up on long exposures)
  • Shake due to IS lens movement (problem seen even with non-IS lenses)
  • Image sensor is loose (nobody else has really eliminated this one, but I'm going to, because I'm pretty sure that if this was the case, the effect would vary significantly with shutter speed)
All of this, and the fact that you refer to this as a pre-production unit, leads me to wonder if perhaps the problem isn't in the camera's firmware and maybe ALSO in whatever software you're using to convert RAW files.

I can't imagine that this wouldn't have been easily noticed before the camera was sent out, but you never know for sure.

Canon doesn't seem to have any downloads for ANYTHING regarding the 1Ds on their website as of yet, but perhaps you could compare firmware version numbers and software version numbers with other people here on the forum who have a 1Ds.

Maybe you could get someone else with a 1Ds to try processing one of your RAW files to see if they get the same results.

Something is definitely wrong =) I was just trying to get some speculation. My friends who are engineers close to imaging sensors couldn't really come up with anything specific, either.

In a way I don't care, it's my employer's camera, mine is on order =) I don't think that my employer strictly speaking needs a fully functional 1DS, so I don't think they will even try to get it fixed (strange thought, eh?)

Anyway, thanks for your input.

Interesting thought. I used the trial version of the Phase One converter, which can be downloaded through this site. I will post a raw image shortly so that anyone can try to convert it.

Thanks for the thought,

Must be nice to be able to dole out $8000 for something, and not really GAS whether or not you get your money's worth!

Just like they say, ...some people have too-much money! ;-)

Larry
 
Let's say that Canon provided the camera for free, because they wanted us to do something with it, and taking pictures is not one of the things. They may want the camera back eventually, but history shows that they never have so far.

I'm glad you posted this. I have a similar problem in my 1Ds. I only noticed it on a couple of shots as I normally don't go in and check out all the pixels at 100% in Photoshop. I was using Canon 17-35, remote release and a tripod.

Mine is going back tomorrow or Friday.

Other than this one deficiency, I absolutely love the camera.

Cheers.

Randy

p.s. I just went back and checked a number of images. They appear fine with no ghosting or anything. The camera is going back for other reasons.

No offense, Stan, but I missed it, too -- and unless I am still missing it, you did not say you tried MLU in your original post. My reaction is that it looks like mirror bounce, but not with a 10" exposure (where MLU is not necessary, anyway).

It's not in the original post. It's in one of the clarification posts. The original post said only something about it happening with all lenses, all iso speeds, tripod or not. Pretty much all initial follow-ups suggested that I should try a tripod and a shorter shutter speed than 10s, so that it doesn't move... Clearly stuff I mentioned.

So I wrote the clarification, among others repeating initial statements, mentioning IS and non-IS, and the use of cable release and mirror pre-lock. I am not aware that this forum would allow me to edit an original post, which may have been helpful.

Sorry if I wasn't clear, but I was hoping that the fact that all images are screwy the same way but that none of the D60 shots have any issues may indicate the possibility that it's not a single isolated occurrence of an error.

Haven't made that many posts here yet, so I am just getting used to this particular group's dynamics. Hope you understand...

According to Canon, IS will misfunction on a tripod (except for the very very latest lenses with the newest generation of IS).

The camera will try to stabilize the image, but it is already stable, you will get this type of image.

Turn IS off. Really.

Ian, I can't seem to find an IS switch on my Canon 17-35 lens. Does your lens have one? I know my 25-135 has one but that is the only lens in my arsenal that has the switch. Is it a hidden feature? :)

Thanks!
