that's why i find the dual card slots extremely useful.
mRaw in the CF and JPG in the SD.
99% of the time, i won't use the RAW files at all since the JPGs work great in the 5D3 out of the camera with the correct picture style used etc..in fact, i often find after editing the RAW files and exporting to jpgs that the original jpg looked 90% identical to the edited raw…so i'd rather save myself the trouble and just use the jpg out of the camera.
However, it's also good to be prepared to have the raw files on another card IF i need it..if not, just format the card…simple as that…
Raw is good to have when you need it but 99% of the time, i don't use it…
