1 All fi gures are approximate. File size varies with scene recorded and make of memory
card.
2 Maximum number of frames that can be stored in memory buff er at ISO 100. Capacity of
memory buff er will drop if noise reduction is on.
3 Total for NEF and JPEG images.
4 Figures assume
RAW Compression
is set to
NEF (RAW)
. Selecting
Comp. NEF (RAW)
decreases fi le size of NEF (RAW) images by approximately forty to fi fty percent; although
camera displays do not change, number of images that can be recorded increases.
5 Figures assume
JPEG Compression
is set to
Size Priority
. Selecting
Optimal Quality
increases fi le size of JPEG images by up to eighty percent; number of images and buff er
capacity drop accordingly.
6 Applies to JPEG images only. Size of NEF (RAW) images can not be changed.
7 Regardless of option chosen for
JPEG Compression
, camera never shows more than 25
frames remaining in buff er, even when more shots can be stored.
