World's toughest⁴ SD card

SF-G series TOUGH specification cards are designed for dependability. The one-piece molding body with high hardness materials is 18 times more bend resistant than the SD standard, impact resistant for drops up to 16.4 m⁵ and high level of dustproofing and waterproofing (IP68).

Fragile parts designed out

By designing out the weak parts of conventional SD cards-the ribs and write-protect switch-reliability is vastly improved. This reduces risk of difficulty in recording data if broken.

Superior water and dust proofing

The fully sealed one-piece molding meets the tough specifications for both waterproofing and dust proofing. With an IP68 rating, the SF-G series TOUGH specification cards can withstand fine dust, mud, grime and immersion in 16.4 ft⁵ of water for up to 72 hours.

World's fastest² SD card

Take burst-shooting and high-resolution video recording to the next level with ultra-fast write speeds up to 299 MB/s³.

V90 for capturing high-resolution video

Support for V90 Video Speed Class makes this card for high-resolution video recording. V90 guarantees minimum write speed of 90 MB/s, for stable recording, even when capturing up to 8K video.

Faster Transfer to PC

With up to 300 MB/s³ read speed, you can transfer large files such as 4K video or a bunch of high-resolution images to a PC expeditiously. Less time waiting, more time doing.

SD Scan Utility

It would be a disaster if your camera suddenly stopped storing images. Over time, all SD memory wears out and the card stops recording data reliably. Sony's SD Scan Utility regularly and automatically scans your SD memory card and lets you know when it's about time to replace it with a fresh card. Disaster avoided. Available for PC and Mac.

Professional reliability

In addition to high level of dust and water proofing, TOUGH specification cards are resistant to X-rays (ISO 7816-1), magnetic fields, UV, and temperature extremes. All while retaining broad compatibility with cameras and other SD card readers.

Recover lost files⁶

Sometimes things go wrong and you accidentally delete files and photos. Memory Card File Rescue is a powerful and easy-to-use tool that recovers data⁶. Available as a free download for Sony memory card customers.
