Sony SF-E Series UHS-II SDXC Memory Card (64 GB / 128 GB)

The SF-E series is Sony's entry point to UHS-II. Both capacities read at up to 270 MB/s, so a card full of 4K clips or high-resolution stills transfers to a computer in seconds. Write speed and video class depend on capacity: the 128 GB card writes at up to 100 MB/s with a V60 rating, while the 64 GB card writes at up to 45 MB/s and carries a V30 rating.

Both are IP57 rated, UV-guarded and built to shrug off dust and water, and both are supported by Sony's downloadable File Rescue software for recovering deleted or unreadable files. A card case is supplied.
