Sensitivity works now, the lens is simply not available for the LX3 I guess.
Thanks a lot for fixing!

I've tested the new release, there's much more information now extracted from
the RW2 files. However, a bit too many. Not all data from the embedded preview
image applies to the raw data, for example:

White balance information - doesn't apply to raw data, the processing software
needs to apply that
Sharpness, Contrast, Saturation, Film mode - also not applicable to RAW data,
these are attributes of the cameras' JPEG rendering process
Digital Zoom - also not applicable to RAW data. It should display "0" anyway, I
think no camera allows enabling digital zoom while shooting RAW.

Not a comprehensive list, I'll make one this weekend.

(From update of attachment 31080)
I've made a list of tags with sensible information for RW2 files. All tags are
marked with KEEP or DROP. I've not commented on undecoded tags

drop JPEG engine tags on rw2 files

This is the patch implementing dropping my suggested list of JPEG engine tags
from the exif data.

Thanks, Matthias! The patch looks good, I'll apply it tonight. It will pose a
challenge once we can write to RW2 images though, as the current logic doesn't
have any provision to ignore tags. But we can worry about this later.
