Memory Card Capacity

The following table shows the approximate number of pictures that can be stored on a 64 GB Sony QD-G64E XQD card at different image quality, image size, and image area settings (as of September 2017).

Includes images taken with non-DX lenses when On is selected for Auto DX crop.

All figures are approximate. File size varies with scene recorded.

Maximum number of exposures that can be stored in memory buffer at ISO 100. May drop in some situations, for example at image qualities marked with a star (“”) or if auto distortion control is on.

Figures assume size-priority JPEG compression. Selecting an image-quality option marked with a star (“”; optimal compression) increases the file size of JPEG images; number of images and buffer capacity drop accordingly.
