phil's exif tool is also available for windows and linux (anything which will run perl, really, which means.. anything out there
). the current version will not extract as much info from the gx10 files as it does from pentax files (i had a quick look, i will look more thoroughly through the definitions when i find some time, as it _should_ be the same for both cameras). meanwhile, anybody with a samsung gx10 running windows can confirm that 1. there is a revision number in the exif, when checking with other software mentioned here, 2. what that revision muber is?
thanks
