Figures are for a Nikon 660GB MC‑CF660G Type B CFexpress memory card (as of March 2023)
with a NIKKOR Z 50mm f/1.8 S lens mounted on the camera.
The number of pictures that can be saved to the memory card or stored in the memory buffer
varies with the scene recorded.
Maximum number of exposures that can be stored in the memory buffer at ISO 100. May drop in
some situations, including when:
an optimal-compression ([m]) option is selected for [Image quality] for pictures shot in JPEG
format or
[ON] is selected for [Auto distortion control].
Figures assume a size-priority option (an option not marked with [m]) is selected for [Image
quality]. Selecting an optimal-compression ([m]) option increases file size; the number of images
and buffer capacity drop accordingly.
Drops when [HLG] is selected for [Tone mode] and [Large] is selected for [Image size].
