Is it possible to find the age of an EOS 1Ds from its serial number?



Also, can the shutter activation count be faked or is it safe to trust it?

I don't believe shutter activation can be faked in camera. I don't know for sure, but I've never heard of it being faked.

I know of no way to track a Canon camera by serial number. Sorry.

Eric

You have piqued my interest, how are you finding the shutter actuation count?
Canon does not normally include it in the exif data, you need a canon service utility to read it, Nikon does include it.

Thanks Eric. It should be pretty safe to take the counter as true then. Do you think 18,500 is high? Not sure what the shutter life is on a 1Ds





PeterP, It's in the EXIF information. It's not labeled as anything interesting, but using Opada's Exif viewer the count seems to be the third figure along on the line labeled "93".



The figure looks right and it increments on each picture so I'm pretty sure that's it

Don't know if that camera is different but other people have told me that the image name will change depending on whats in the camera's card.

For example, if the image is IMG_4449 then the camera will think the next image is IMG_4450 and it will name it as so. Don't know if the exif works the same way or not.

Maybe it is the version of Opanda I have 2.2.
I don't see any line with a value of 93, or anything that looks like a shutter actuation count. I've enabled show all exif fields for the images I testing with. (using opands powerexif editor).

DOn't doubt it is there, I'd like to find it myself

Wouldn't reflashing the camera - i.e. a firmware load/upgrade reset any counter?

Good point NHL, don't know what a firmware flash would do to it.

Think I found part of my problem, I was trying to use images from a 20D.
Canon moved that info somewhere else on that camera, item 93 no longer exists for it.
From my web *****hing you need the Canon 20D service utility to read it out of the camera. Of course that service utility is not available to mere mortals.

That field 93 does exist on the 10D and 1d cameras, not sure about the mark II's and 5d though.
I wonder why they make it so hard to find that information.

If mere mortals can have the service utility to read - then so is the write access! :-)

Unless this info is lock away in a seperate block, a flash is not like a random access memory where one can individually write to a byte or a word. An entire block is usually required to be erased before new data can be written to them...
