The listed specs show slots for CF and SD cards. Without getting into the technical superiority of CF cards can anyone tell me, based on experience with other dual slot cameras if a CF card is required. If have over 110 gigs of class 10 SD cards but no CF cards.
The 5DIII has one CF, one SD card slot like the 7D2.
I think this is a great arrangement. I write RAW to a fast CF card and simultaneous small or med JPG to the SD card, which is an eye-fi card.
This strategy gives me RAW for later, and instant medium jpg which goes wirelessly to my android and to the online storage. The JPGs are immediately available for SM needs, and the RAWs can be processed later.
The wifi can be turned off in camera when you don't want instant processing/review.
