The Sony FX2 arrives on the market as a true revolution for all content creators and professional 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 appeal to those looking to get started in professional video, documentary, or run-and-gun photography.
But to take full advantage of this little technological bomb, it's 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, yet it's essential to guarantee smooth 4K recordings, without interruptions or slowdowns. In this article, I'll guide you to find the best SD card for the Sony FX2, with a detailed comparison of the essential models of the moment – to film with peace of mind and exploit the full potential 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 can match its capabilities! Filming in 10-bit 4K or recording long sequences in run-and-gun mode requires high write speeds and flawless reliability. A slow SD card can quickly become a nightmare: cutouts 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 compatible with CFexpress Type A and one compatible with SD UHS-II, 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 SD UHS-II card. Otherwise, the camera will automatically limit certain recording options. In short, the SD card is not just an “accessory”: it’s a real key link in your professional workflow!
Recommended SD cards for the Sony FX2: selection criteria
With so many models on the market, it's not always easy to know which SD card to choose for your Sony FX2. However, there are a few key criteria that can help you sort through them quickly. First, always choose UHS-II cards , which offer much higher read and write speeds than traditional UHS-I cards—this is essential to take full advantage of the FX2's high resolutions and frame rates.
Capacity is also a consideration: a 256GB, 512GB, or even larger card will allow you to film stress-free, especially during long shoots or documentaries. Finally, reliability and durability are essential, especially if you're working outdoors: opt for robust, reputable models that can withstand heat, humidity, and shock.

Frequently Asked Questions about SD cards for the Sony FX2 (FAQ)
Should you use a UHS-II SD card or a CFexpress Type A card with the Sony FX2? The FX2 has two slots: one for UHS-II SD cards and one for CFexpress Type A cards. For most video uses, a good UHS-II SD card is more than sufficient and offers excellent value for money. CFexpress Type A cards are still recommended for more intensive needs (slow motion, long 4K sessions, RAW), but are significantly more expensive.
What SD card capacity should you choose for filming in 4K? In 4K, the files are very large! A 256 GB card already allows you to film for several hours, but if you're filming in succession or going on a trip, 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 you mix different brands or types of cards in the FX2? Yes, you can use two cards of different brands or capacities. However, be sure to follow Sony's recommended minimum speed to avoid any limitations or error messages when recording video.
What are the signs of a slow or failing SD card? Recording stops, “buffer full” error messages, or corrupted files are signs of a slow or dying card. If this happens to you, quickly upgrade to a better card, like the Lexar SILVER PRO SD Card .
How to properly maintain your SD cards to extend their lifespan?
Always format the card in the camera before an important shoot.
Avoid filling it 100%: leave a margin for more stability.
Store your cards in a case away from humidity and heat.
Remember to renew your SD cards every 2 to 3 years with heavy 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 keep your footage safe, there are a few best practices you should follow:
Always format your SD cards in the Sony FX2 (not on your computer) before each new project. This maximizes compatibility and reduces the risk of bugs during recording.
Avoid filling your cards to 100% : always keep a small margin of free space, this helps preserve performance and limits file fragmentation.
Backup as often as possible, especially during important shoots. Always carry one or two backup cards (e.g., a Gigastone 256GB SDXC Memory Card ), this will prevent unpleasant surprises if one card shows signs of weakness.
Store your SD cards in a dedicated case , protected from dust, moisture, and shock. Rugged models like the Sony 512 GB Tough M Series UHS-II SDXC Memory Card are ideal for field use, but a minimum of precaution is always recommended.
Test your SD cards regularly with speed checking tools: this helps you anticipate possible performance drops.
Renew your SD cards every 2 to 3 years under heavy use, even if they're still working. Memory cells eventually wear out, so prevention is better than cure!
By following these tips, you'll have the best chance of enjoying your SD cards for a long time, without losing files or unpleasant surprises at crucial moments.
