Putting the Secure in Secure Digital. This Sony 128GB SF-G Tough Series memory card provides fast write speeds in a heavy-duty SD casing. Sony touts the cards as bend-proof, drop-proof to 5 meters, x-ray-proof, magnet-proof, static-proof, UV-proof, and temperature resistant. It is waterproof IPX8 and dust-proof IP6X rated which enables the card to be submerged to 5 meters of water for 72 hours. Rounding out the durable build is a robust TOUGH displayed across an industrial-yellow colored background.
V90, UHS-II, SDXC Memory Card. The Tough Series SD cards are UHS-II capable for write speeds up to 299 MB/s. This grants the card a V90 rating for high-resolution, high-bitrate video capture from cameras like the Panasonic GH5S, Fuji X-T3, Panasonic EVA1, Blackmagic URSA Mini Pro, & Blackmagic Pocket Cinema Camera 4K.
Other Features. In order to increase the rigidity of the case, the write protection switch has been removed. This UHS-II card is backward compatible with UHS-I cameras but will only provide a write speed of 90 MB/s which is often not enough for 4K capture.
