Ideal for high-speed continuous shooting to capture every moment

NX-A1PRO Series is designed for professional users who handle high-speed continuous shooting and high bit rate videos.
With fast write/read speeds, it ensures stable photo shooting at the highest quality and shortens data transfer time for a seamless workflow from ingesting to editing.


NX-A1PRO Series achieved a maximum read/write speed of 950 MB/s and a minimum sustained write speed of 850 MB/s1,2, increases the number of continuous shots during high-speed continuous shooting and further reduces the buffer memory release time3.
The high-speed data transfer maximizes camera performance and minimizes buffer release time, efficiently supporting users capturing moments through photography.


The NX-A1PRO Series CFexpress Type A card is equipped with Nextorage’s Dynamic Auto Power Save, a power saving system that reduces 88 %2 power consumption in video recording compared to non-equipped pSLC CFexpress cards ― contributes not only to saving the camera’s battery life, but to maintaining sustained write speed by suppressing thermal throttling.3

*Thermal throttling: a control function that suppresses the transfer speed to prevent thermal runaway


All capacities compliant with Video Performance Guarantee, VPG400 (400 MB/s minimum sustained write speed).
It is essential for professionals to film high-quality, 4K and 8K videos, and supports fast and stable recording.4
