Am I right that I have to use the DNG converter before I can use 5D2 files in CS2?

Unless you use lightroom 2 and open to CS2 from there you will need to convert to DNG

Is there a downside to converting to DNG? In other words, would there be any reason to keep the RAW file after converting?

The converted DNG wouldn't be a valid original for challenges.

Ya, that's good news to know. How about outside DPC world? I shoot RAW+JPG and I could keep the small JPG for validation. It just seems like a lot of space when it's 45 MB a pic...

I didn't think you could use the jpeg version if you used the raw file for the entry, maybe I'm wrong.

Yep, that would work fine.

I would suggest upgrading to CS4 or Lightroom 2. I did the DNG converter thing for a little while but quit because I didn't want to delete the CR2 files so I ended up keeping two versions for every shot I kept. At 50 megs a pop disk space started dwindling fast.

Im going to dito yanko on the upgrading to CS4. I ran in to the same problems when I started shooting raw with my D300, CS2 was not working, Even with the DNG converter, so I upgraded to CS4 and have no regrets.

I ran into exactly the same problem with my 5D mkII.

I got Lightroom 2 and that seems to work nicely for what I need.

Yes. From the rules: "DNG files are not considered originals unless recorded in that format by the camera."

The DNG is actually just a wrapper around the RAW data, so in theory the RAW file is still there. There's also an option for embedding the RAW file so that it can be re-extracted, though why anyone would do that is unclear to me; it doubles the required space. The only real risk in using DNG is if the format dies out, nobody supports reading it anymore, and you have to convert all your DNGs to something else to maintain access to your data. Of course, there is a similar risk with RAW files. At *some* point we will all probably wind up converting old RAW data to a newer format. For myself, I'm sticking with the Canon RAWs.
Here's an interesting idea; download the Lightroom 3.0 beta for free and play with it for a few months. I pretty much guarantee that you'll be a Lr convert. I use it both at home and at work to manage my image catalog and streamline my workflow.
