He has the *ist DS. It hasn't been out that long. Apparently, even though the extension is the same as the *ist D RAW files, the files are a little bit different. It doesn't surprise me that Adobe doen't have a converter available yet. I'm not saying they shouldn't have one - they should. It just doesn't surprise me.
As for using Bibble and BreezeBrowser, I'm all for it. I have Photoshop CS, but I still use BreezeBrowser for browsing my RAW files because it's so much faster than the Photoshop browser. And the little guys are sometimes faster than Adobe at delivering new conversion software.
By the way, for all of you using Photoshop CS, BreezeBrowser, etc, we need more software reviews. And there is a contest until the end of the month. You have a few more days before the end of the year to post your reviews and qualify to win the Pentax Optio SV.
