HUH? jpegs and mp3s are lossy compression, although I
must say that each at their highest possible settings
( minimum compression ) are pretty good.

In theory:

Take a PEF file out of a K10D and DNG as well.
convert to JPEG using  *exactly* the same settings. Compare output. If
outputs are the same then it is lossless.

IMO, there 's no point in lossy compression. Zip archives are compressed
and are lossless. Compression does NOT necessarily loss in any way. IMO
JPEGs/MP3s and such things shouldn't called "compressed" BTW.
