Memory Card Capacity

The following table shows buffer capacity and the approximate number of pictures that can be stored on a 128 GB¹ card at different image qualities and sizes when [FX (36 × 24)] is selected for [Choose image area]. Actual capacity varies with shooting conditions and the type of card.

Figures are for a SONY CEB-G128 CFexpress memory card (as of August 2020).
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]
- [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.
