[edit, this is an post from 2009, which was an update from 2008 and now it's time to bump the post again as there is a smaller update made that I didn't know about].
Jeff Sickels, the creater of Sigma X3F quicklook plugin has once more shown his skill and released a welcome update. He made this comment a while back:
There’s a new version of the X3F_qlgenerator out that now uses x3f_extract. It handles the DP1 X3F files significantly better than earlier versions (a plus), and keeps the same orientation enhancements from v1.2. Thanks to Carl’s RAW DP2 Pack, I was also able to verify that Quicklook handles the DP2 files rather well (now I just have to get my hands on a DP2). Enjoy.
