Additionally, it offers backward compatibility with select XQD-enabled host cameras via a firmware update, giving a future-proof life extension to existing pro-tier gear.

Built to withstand punishing assignments on remote locations, this card retains structural integrity in extreme environments. It operates smoothly in temperature ranges from -25°C to 85°C.
