The Sony FX2 comes to market as a real revolution for all professional content creators and videographers looking for a compact, lightweight and affordable cinema camera. With its full-frame sensor, impressive image quality and features worthy of the most high-end models, the FX2 has everything to seduce those who want to get into professional video, documentary, or run and gun.
But to take full advantage of this little technological bomb, it is not enough to choose the right lens or the right accessories: the choice of SD card is just as strategic! Too many videographers underestimate the importance of this component, which is essential to ensure smooth 4K recordings without interruptions or slowdowns. In this article, I’ll guide you through finding the best SD card for the Sony FX2, with a detailed comparison of the must-have models of the moment – so you can shoot with peace of mind and get the most out of your new cinema camera.
Why SD card choice is crucial for the Sony FX2
While the Sony FX2 is designed for performance and versatility, it also requires a memory card that matches its capabilities! Indeed, filming in 4K 10-bit or recording long sequences in run and gun mode requires a high writing speed and flawless reliability. An SD card that is too slow can quickly become a nightmare: cuts during recording, corrupted files or even the inability to film in the advanced formats offered by the FX2.
The FX2 is equipped with two slots: one CFexpress Type A compatible and one UHS-II SD compatible, which offers great flexibility. But be careful: to benefit from the best settings (especially in 4K 60p or with advanced log profiles), it is imperative to choose a high-performance UHS-II SD card. Otherwise, the camera will automatically limit certain recording options. In short, the SD card is not just an “accessory”: it is a real key link in your professional workflow!
Recommended SD cards for the Sony FX2: how to choose
Faced with the multitude of models on the market, it is not always easy to know which SD card to choose for your Sony FX2. However, there are a few essential criteria that allow you to sort through the process quickly. First point: always choose UHS-II cards, which offer much higher read and write speeds than conventional UHS-I cards – this is essential to take full advantage of the FX2’s high resolutions and high frame rates.
The capacity is also to be taken into account: a 256 GB, 512 GB or even more card will allow you to film without stress, especially during long shoots or documentaries. Finally, reliability and resistance are paramount, especially if you work outdoors: opt for robust and reputable models that can withstand heat, humidity and shocks.

Frequently asked questions about SD cards for the Sony FX2 (FAQ)
Should you choose a UHS-II SD card or a CFexpress Type A with the Sony FX2?The FX2 has two slots: one for UHS-II SD cards and one for CFexpress Type A cards. For the majority of video uses, a good UHS-II SD card is more than enough and offers excellent value for money. The CFexpress Type A is still recommended for the most intensive needs (slow motion, long 4K sessions, RAW), but is much more expensive.
What SD card capacity should I choose to shoot in 4K?In 4K, the files are very large! A 256 GB card can already film for several hours, but if you’re shooting or traveling, choose a SanDisk 512 GB Extreme PRO SD card or a Sony 512 GB Tough M Series UHS-II SDXC Memory Card to avoid having to transfer your files too often.
Can I mix different brands or types of cards in the FX2?Yes, it is possible to use two cards of different brands or capacities. However, be sure to follow Sony’s recommended minimum speed to avoid any throttling or error messages when recording video.
What are the signs of an SD card that is too slow or failing?Stops recording, buffer full error messages, or corrupted files are signs of a card that is too slow or at the end of its life. If this happens to you, quickly switch to a more capable card, such as the Lexar SILVER PRO SD Card.
How to properly maintain your SD cards to extend their life?
- Always format the card in the camera before a major shoot.
- Avoid filling it to 100%: leave a margin for stability.
- Store your cards in a case away from moisture and heat.
- Remember to renew your SD cards every 2 to 3 years for intensive use.
Our tips for extending the life of your SD cards
Investing in a good SD card is essential. But to ensure its longevity and guarantee the safety of your rushes, a few good practices are necessary:
- Always format your SD cards in the Sony FX2 (not on the computer) before each new project. This optimizes their compatibility and limits the risk of bugs during registration.
- Avoid filling your cards to 100% : Always keep a small amount of free space, which helps preserve performance and limits file fragmentation.
- Multiply backups as soon as possible, especially during large shoots. Always carry one or two backup cards (e.g. a Gigastone 256GB SDXC memory card), this avoids unpleasant surprises if a card shows signs of weakness.
- Store your SD cards in a dedicated case, away from dust, moisture and shocks. Rugged models like the Sony 512 GB Tough M Series UHS-II SDXC Memory Card are perfect for field use, but a minimum of caution is always recommended.
- Test your SD cards regularly with speed check tools: this helps anticipate possible drops in performance.
- Renew your SD cards every 2-3 years for heavy use, even if they are still working. Memory cells always end up wearing out, better safe than sorry!
By applying these tips, you put all the chances on your side to enjoy your SD cards for a long time, without losing files or unpleasant surprises at the crucial moment.
