Hi Beau,
Yeah. I was looking, unsuccessfully, for something like that. Couldn't find anything. But. Panasonic came up with a firmware update. Which I installed. And I think the issue has been resolved. I seem to be getting the exposure I see on the camera LCD screen ... in the computer when I import the stills. There is still a slight difference, a stop or so, between the jpg versions and the RAW versions. Darker on the RAW.
So maybe it had something to do with the previous firmware update. When I first got the camera there was no issue at all, regarding exposures.
All the best,
Ben
