Incidentally - as regards EXIF and manual lenses, I wish Panasonic would introduce a few little enhancements in firmware:
- Being able to setup some stored lens info that you can then retrieve. Olympus do this for up to four lenses. You can store the lens name, focal length, and max aperture. If you select the lens, it sets the exif data and also sets the focal length into the IBIS.
- Being able to use one of the control wheels to record the aperture you used at time of capture.
I don't think either would be a huge amount of coding, but it would sure improve things for people using manual lenses.
