The most robust in the world1: 18 times higher bending strength
The ultra-rugged resin cast design makes the SF-M series cards with TOUGH specification 18 times more flexible than standard SD cards.
Waterproof and dustproof according to IP68
The SF-M Series cards with TOUGH specification will last up to 72 hours at a depth of 5 meters under water and are dustproof all around. So you are optimally protected in every shooting situation.
Shockproof: Can withstand falls from a height of up to 5 metres
The SF-M series one-piece cast card with TOUGH specification made of extra strong materials can withstand falls from up to 5m2.
Grooveless design without write protection switch
The SF-M series TOUGH specification cards do not require the sensitive connection grooves and write-protect switches found on conventional SD cards, as these parts break easily and can prevent writing.
Robust, one-piece cast design
These cards consist of a cast molded design and reliable materials. Professionals and amateur photographers can concentrate on their work anywhere.
Rapid writing speed
With a fast write speed of up to 150 MB/s³, these cards allow longer continuous shooting of high-resolution photos and clear the memory buffer faster.
Scans and checks your memory card
SD Memory Cards cannot reliably store data after a certain period of time. The SD Scan Utility scans your SD memory card so that you are informed in advance. Available as a free download.
Optimized for HD video with V60
The cards support V60 video speed for stable 4K and high bitrate video recording. Ideal for recording all types of high-definition video.
Super fast backup and data transfer
Faster transmission and backup means more time for the actual recording. The extremely fast reading speed of up to 277 MB/s³ ensures that even the largest media files can be transferred to a computer in seconds.
Retrieve lost data
If something goes wrong, simply restore photos and videos that have been accidentally deleted or cannot be played back with Rescue Software to download from Sony. Available as a free download.
