CFexpress Type A reader for CEA-G cards

This USB card reader supports CFexpress Type A version 4 media and is optimised for Sony CEA-G series cards. It connects to most PCs, smartphones and tablets for direct offload in the field or studio. The compact design makes it practical for mobile workflows where internal slots are unavailable.

Upgrades from slower USB 3 card readers
