Memory Card Capacity
The following table shows buffer capacity and the approximate number of pictures that can be stored on a 660 GB 1 card at different image qualities (0Adjusting Image Quality), and sizes (0Choosing an Image Size) with [FX (36 × 24)] selected for [Choose image area] and [SDR] selected for [Tone mode]. Actual capacity varies with shooting conditions and the type of card.
|Image quality||Image size||File size||Number of exposures remaining 2||Buffer capacity 2, 3|
|NEF (RAW), lossless compression||—||Approx. 51.6 MB||7300 frames||81 frames|
|NEF (RAW), high efficiencym||—||Approx. 32.6 MB||17,200 frames||599 frames|
|NEF (RAW), high efficiency||—||Approx. 21.1 MB||24,200 frames||Over 1000 frames|
|JPEG/HEIF fine 4||Large||Approx. 19.0 MB||20,900 frames||Over 1000 frames 5|
|Medium||Approx. 12.4 MB||35,900 frames|
|Small||Approx. 6.7 MB||69,900 frames|
|JPEG/HEIF normal 4||Large||Approx. 11.8 MB||41,900 frames||Over 1000 frames 5|
|Medium||Approx. 7.0 MB||69,900 frames|
|Small||Approx. 3.5 MB||139,000 frames|
|JPEG/HEIF basic 4||Large||Approx. 4.0 MB||78,600 frames||Over 1000 frames 5|
|Medium||Approx. 2.7 MB||125,000 frames|
|Small||Approx. 1.8 MB||251,000 frames|
Figures are for a Nikon 660 GB 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].
