As far as we know, no software has ever read the shutter count from a Canon EOS-1Ds Mark III — ours included.
We've built support for it from the camera's own firmware, but we've never had a real Canon EOS-1Ds Mark III to try it on, so we can't promise it works yet.
If you have one, a free check with our desktop app on Windows or Mac would settle it in about a minute — and you could be the first person ever to get a count out of this body.
