Sony had announced their new line of SD cards called Sony SF-G TOUGH series. Sony hopes to solve the age old problem that plague photographers with SD cards. Conventional SD cards are notorious for breaking, being flimsy and the occasional corruption of files. That’s where these Sony SF-G TOUGH SD cards come in. Sony claims that these are the fastest and toughest SD cards ever made.
These cards can reach a write speed of 299MB/s and a read speed of 300MB/s. Sony incorporated their SF-G specification, which means these cards are 18 times stronger than regular SD cards, it’s X-Ray proof, it’s magnet proof, antistatic, temperature proof and has UV guard. It's suppose to be bend proof (up to 180 Newton of force) and drop proof (from 5m (16ft)). It's waterproof and dust-proof with a world-class rating of IPX8 and IP6X. Sony will even include, to keep your work safe, an SD Scan Utility and File Rescue Software. That's awesome if you ask me. It seems Sony is really trying to cater to pro photographers so they never loose their work.
Conventional SD cards are made up of three thin pieces: the plastic casing, a data protection switch and a connecter rib. In order to make this card waterproof, dust-proof and less prone to file corruption, Sony made this card as a one piece moulding structure for strength and hardness without the data protection lock or connection ribs. With this design, Sony can reach those TOUGH specification they were aiming for. The video below shows a bend stress test between a regular SD card vs the new Sony SF-G TOUGH SD card:
WHAT DOES THIS MEAN FOR EVERYONE?
While newer cameras have the SD UHS-II standard, most people have SD UHS-I in their cameras. The benefit of buying a SD UHS-II card for your camera that only accepts SD UHS-I is that the UHS-II standard is backwards compatible with UHS-I, so in other words, a UHS-II card will work with a camera that only accepts UHS-I. Of course, it does come with a minor caveat, which is, you won’t be able to benefit from the full speed of UHS-II. UHS-I has 9 pins and UHS-II has 17 pins. Those 8 extra pins is what makes this card go so fast. When you insert a UHS-II into a camera that only accepts UHS-I, the camera’s card reader will only use the first 9 pins, which is the reason why UHS-II is backwards compatible.
All this is to say that if your camera can only use SD UHS-I, we recommend getting this card to benefit from these awesome features. For pro photographers, it would be essential to have these cards in our bags. Also, if you do have a camera that has SD UHS-II, go for it.
At this point, pricing and availability is not available at the moment. A 32GB, 64GB and 128GB capacities will be available. US availability is still unknown but will have an October launch in Europe.
