Memory Card Capacity

The following table shows buffer capacity and the approximate number of pictures that can be stored on a 325 GB¹ card at different image qualities (0Adjusting Image Quality) and sizes (0Choosing an Image Size) when [FX (36 × 24)] is selected for [Choose image area]. 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. 55.1 MB	3600 frames	79 frames
NEF (RAW), high efficiencym	—	Approx. 33.0 MB	8500 frames	685 frames
NEF (RAW), high efficiency	—	Approx. 22.0 MB	12,100 frames	Over 1000 frames
JPEG fine ⁴	Large	Approx. 24.1 MB	10,400 frames	Over 1000 frames
	Medium	Approx. 14.3 MB	17,700 frames
	Small	Approx. 7.0 MB	35,400 frames
JPEG normal ⁴	Large	Approx. 12.2 MB	20,600 frames	Over 1000 frames
	Medium	Approx. 7.2 MB	34,400 frames
	Small	Approx. 3.6 MB	68,800 frames
JPEG basic ⁴	Large	Approx. 5.3 MB	39,900 frames	Over 1000 frames
	Medium	Approx. 3.4 MB	65,200 frames
	Small	Approx. 1.9 MB	123,000 frames

Figures are for a ProGrade Digital COBALT 1700R 325GB memory card (as of September 2021) with a NIKKOR Z 50mm f/1.8S lens mounted on the camera.

Number of pictures that can be saved to memory card or stored in memory buffer varies with scene recorded.

Maximum number of exposures that can be stored in memory buffer at ISO 100. May drop in some situations, including when:

an optimal-compression ([m]) JPEG option is selected for [Image quality] 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.
