Neither Bridge CS4 nor PhotoShop CS4 (both fully updated) recognise the format despite CR2 being listed in the Bridge file associations for PhotoShop CS4.
In Bridge I just get a file icon.
In PhotoShop I get a 'file type not recognised' type of message.
Must I use Canon Digital Photo Profession to convert to TIF for processing in Adobe Camera Raw, or am I missing something?
See this: <http://www.adobe.com/products/photoshop/cameraraw.html>
Is it not reasonable to expect that the CR2 format is consistent between cameras and that therefore if the RAW output from one camera generating CS2 can be handled, then so can another?
Or don't RAW files with the same extension share a common file format?
No
The Adobe ACR forum often carries threads on this subject:-

See this TechNote for opening any RAW file in Adobe applications:-

You might think so but if you knew what data goes into those files you would know it is impossible. Think of the number of Canon camera models.
It would be reasonable to give different file names maybe. But they don't.
I've tried the DNG converter, but that won't touch them either.
I've put in a feature request.
The camera update allows both JPG and RAW to be saved in parallel, so I can store the .CR2 files pending access in CS4.
I don't know about Canon, but Nikon's NEF files are specific to the camera
model which produced them.
