After Sony announced their G Series XQD version 2 memory cards, Nikon updated the buffer performance of the D4s camera – in the tables below the left “Buffer Capacity” column shows the approximate number of pictures that can be stored with the older Sony 32GB S Series XQD memory card (QD-S32E) at different image quality, image size, and image area settings. The right (yellow) “New Buffer Capacity” column shows the approximate number of pictures that can be stored with the new Sony 64GB G Series XQD memory card (QD-G64):
Nikon XQD memory card buffer capacity FX 24×36
Nikon XQD memory card buffer capacity DX 24×16 *2
*1 Includes images taken with non-DX lenses when On is selected for Auto DX crop.
*2 Includes images taken with DX lenses when On is selected for Auto DX crop.
*3 All figures are approximate. File size varies with scene recorded.
*4 Maximum number of exposures that can be stored in memory buffer at ISO 100. Drops if Optimal quality is selected for JPEG/TIFF recording > JPEG compression or auto distortion control is on.
*5 Figures assume JPEG/TIFF recording > JPEG compression is set to Size priority. Selecting Optimal quality increases the file size of JPEG images; number of images and buffer capacity drop accordingly
The new Sony XQD memory cards are available for pre-order at B&H and Adorama.
