CF or SD in 5D III


I do understand the camera writes faster to a CF card but slower to SD card.

Granted the difference, I am interested to know how others make use of the two slots.


Would you use:


  • Only CF
  • Only SD
  • Writing both to CF and SD in RAW
  • Write to CF in RAW and SD in Jpeg

Note: I do not have the 5D IIII until I take delivery this weekend.
