Memory Card Capacity
The following table shows the approximate number of pictures that can be stored on
a 8 GB SanDisk Extreme Pro SDHC UHS-I card at different image quality and size
settings. Note that buffer capacity drops at ISO sensitivities of 1600 or higher.

1 All figures are approximate. Results will vary with card type, camera settings, and scene recorded.
2 Maximum number of exposures that can be stored in memory buffer at ISO 100. Drops when noise
reduction (0 131) or auto distortion control (0 130) is on.
3 Image size applies to JPEG images only. Size of NEF (RAW) images can not be changed. File size is the
total for NEF (RAW) and JPEG images.

File Names
Photographs are stored as image files with names of the form "DSC_nnnn.xxx, " where nnnn
is a four-digit number between 0001 and 9999 assigned automatically in ascending order by
the camera, and xxx is one of the following three letter extensions: "NEF" for NEF images,
"JPG" for JPEG images, or "MOV" for movies. The NEF and JPEG files recorded at a setting of
NEF (RAW) + JPEG fine have the same file names but different extensions. Copies created
n
with image overlay (0 155) and movie edit options (0 93) have file names beginning with
"DSC_" ; copies created with the other options in the retouch menu have file names
beginning with "CSC" (e.g., "CSC_0001.JPG"). Images recorded with the Color space option
in the shooting menu set to Adobe RGB (0 130) have names that begin with an underscore
(e.g., "_DSC0001.JPG").
