RAW not yet supported

And that may be less than an accurate statement. Especially if the camera in question in Canon 5Ds.

so your assumption is that OP got a raw file and did not try Adobe converters available  ? ... "nu nu" (c)

Even Canon's? As Kirk points out, seems unlikely that a camera with the ability to shoot raw would come with no way of actually using the raw files."IF" indeed no converter supports it, no converter supports it. The key here is 'if' as far too little about the file in question has (or can be?) answered.

What I'm saying is - new Canon 5Ds[R] may be in fact supported by some converters. On the other hand, some cameras do not really came out, they just appeared - so those who received bootleg raw files may have no access to the necessary version of, say, DPP.

No, that is not my assumption.

the question is whether he has the camera and bundled software or just the raw file ... so do ACR/LR open Canon raw files from 5Ds w/o changing camera's model inside ?

The OP states NO converter can open the raw file. So that pretty much ends the debate if true.

There's lots of questions and lots of assumptions. Why go there?

Maybe the issue is this is something other than a raw file. Maybe WWE RAW?

peace.

Can someone tell me if there is any chance to open a RAW not yet supported by any converter?
Thank you!

If taken literally, the simple answer to this question is: NO!

In light of the fact that the OP has declined to provide any additional information, I am amazed and amused by the amount of speculation and circular discussion contained in this thread.

All this sound and fury and the OP has never explained anything at all. Yet the forum beat it to death and it is destined for an unmarked grave.
