True, but probably Pentax firmware uses this embedded JPEG data for the image
previews, and *not* the raw data (just because this way the same algorithm
can be used to display both RAW and JPEG pictures). The fact that even the
histograms seem to be based on the JPEG data is quite significant. There's
probably a fast harware-assisted JPEG compression engine, so the whole
firmware heavily relies on JPEG data for all operations. RAW output is just
an extra in the data fow then.
Using JPEG can even make zooming in/out during preview much easier and
faster.
Yep... but it's an awful high price to pay for a feature that is
often not used. I'd rather have slower zoom in/out on preview (that I
rarely use) than wast 15% storage on a low-quality JPEG.
To each their own, I guess. Sucks to be an engineer...
