Using Two Memory Cards
When two memory cards are inserted in the camera, you can use
the Role played by card in Slot 2 item in the photo shooting
menu to choose the role played by the card in Slot 2. Choose from
Overflow (the card in Slot 2 is used only when the card in Slot 1 is
full), Backup (each picture is recorded twice, once to the card in
Slot 1 and again to the card in Slot 2), and RAW Slot 1 - JPEG Slot
2 (as for Backup, except that the NEF/RAW copies of photos
recorded at settings of NEF/RAW + JPEG are recorded only to the
card in Slot 1 and the JPEG copies only to the card in Slot 2).
A
“Backup” and “RAW Slot 1 - JPEG Slot 2”
When Backup or RAW Slot 1 - JPEG Slot 2 is selected, the camera
shows the number of exposures remaining on the card with the least
amount of memory, and voice memos (
0 272) are recorded to the card
in Slot 1. Shutter release will be disabled when either card is full.

Recording Movies
When two memory cards are inserted in the camera, the slot used to
record movies can be selected using the Destination option in the
movie shooting menu (
0 296).
