Before my last trip I set the recording mode to RAW+JPG.
I haven't changed that setting for the entire trip, however when I got back home and imported the pictures into lightroom, I found that several of those were just jpg (eg. no equivalent RAW files saved). What is strange is that it seems to have changed at some point, roughly in the middle of the second day, when the camera has apparently started recording both RAW and JPGs.
I am positive I haven't changed the setting.. do you have any possible explanation? has anybody else had the same problem?
