I just got this from the folks at Phase One ... 7D is supported in the new release of Capture One 5 but ... Ian- We will not be upgrading version 4 any longer. You will need to purchase the upgrade to version 5. You can do so from our website (E Shop) for $99.00. You may also choose to download Capture One 5 and run it in trial mode for 30 days to see if the fee is something you'd like to spend. Kind Regards Phase One Support
Pooh. I suspect that Adobe will be doing similar with LR3 and the next version of ACR though. Right now, us 7D users are just a little bit at their mercy. :meh:
