A small update with a better look at some features.....
In the latest CPN Newsletter form Canon Europe, they herald DPP4 as the 'First major update of the software since it was launched"
It is still compatible ONLY with current FF sensor cameras, thus leaving out even the 1Ds III, 1D IV, 5D mkII, 7D and all other Canon Cameras.
It adds " (although support for more models will be added in due course)"
DPP has always been a free converter/editor utility for all Canon Cameras, and always provided ecxelent conversions, but DPP4 aspires to do more than that, which is welcome.
The good news is that they are saying 'more' models will be added "in due course" (2 weeks, 2 months, 2 years??) But, they are saying 'more models' not' all models', so some camera models will be left out of DPP4's functionality. For those left out, they have said they will continue to supply a version of DPP 3.x.x. (although they have not said how long they will provide it, or if they intend to update two different versions for Windows & MacOS for the forseeable future ??)
DPP4 looks much improved.
I'm not a software engineer, I don't know if the different DIGIC processor versions could be a factor in their decision to include a 6D but Exclude 1DsIII &5D II, or why it would be easier to upgrade two different versions of DPP long term rather than to roll them into one. (There may be a good reason for that, but it seems counter-intuitive [and also a marketing mistake] to me) Perhaps someone with expertise in that area could help clarify...?
There is an opportunity to Download DPP4 but I think you need files from one of the 4 supported Cameras to try it.
I can't imagine Canon would go to all this work to support only 4 cameras,(or why it makes any sense to launch this way), so I'll remain hopeful
