Besides Canons own Digital Photography Professional software, RAW processing software supporting Canon EOS 7D are still sparse. But now PhaseONE has released the latest version of their Capture ONE RAW converter and workflow software which includes support for EOS 7D RAW files.
The software are available as a 30 days free trial download.
Some time ago I was at a Canon arrangement presenting the 7D, and was told that Canon Denmark and PhaseONE was trying to intensify their cooperation. So it might be software worth trying?
