Yep,
either:
- convert your 7D files to DNG; or
- download the release 3 alpha.
I've been destruction-testing various incarnations of r3 alpha for a good while now, and with the caveats that it's
obviously an alpha release (there's a new version every day or two, as the devs add, remove, tweak or otherwise fettle the myriad brilliant - and often unique - bits of functionality), and that it can take longer than might be ideal to process each file - they're working on that - the results are
excellent.
Be aware too that some builds can be a bit unstable on some machines.
There's a lot going on in RT 3 - it provides a truly daunting set of options (there are no less than
nine different noise reduction tools for example, including a gem of a "line noise" filter which does a great job if your 7D is prone to low ISO banding) - and eight different demosaicing algorithms, so it's a bit intimidating.
Worth putting the effort into though, if you're so inclined. I am: once the devs decide on the date of the feature freeze so that they can then release a stable beta version, I'll be writing some of the user guides for the project, so I'll hopefully be able to help if you have any questions.
I'd suggest you start by giving
this build a try - it's been pretty stable on my Win 7 machine, and has the latest feature set.
