still waiting for mine but I've allready looked at the manual, and with GR it's only raw + (jpeg L) :
sorry, it's the french manual :
Seems to me that they have done away with the second menu that allows to to choose what size jpg you get to go with your RAW+ setting (or no jpg just an embedded VGA size jpg inside the RAW file). The new deal seems to be an embedded L size jpg which would probably provide a better playback image.
Also you can get an L size image along wih a RAW file. However they seem to have lost the difference between "Large" and "Large-fine". Maybe this is no longer relevent for the larger sensor used?
In any case this should satisfy the raw-freaks who will stop at nothing to get a very large RAW file complete with embedded full size jpg instead of just regular RAW file size plus a separate jpg file so that they can choose which of the two files to use and which to discard. The latter seems much a more common sense approach.
I suppose that is a case of the manufacturer listening to noisy user demands and giving them a sort of "nonsensical" improvement.
I would be happy to listen to reasoned argument why it is absolutely necessary to have a full sized jpg file embedded inside a RAW file.
