ProGrade Digital CFexpress 4.0 Type A Iridium View on Amazon
ProGrade Digital has become a go-to brand for many professionals, and their CFexpress 4.0 Type A Iridium cards showcase why. Designed for emerging imaging applications, these cards push boundaries with max read speeds of up to 1800 MB/s and write speeds up to 1700 MB/s. What’s truly standout is their sustained write performance, with the 960GB version capable of an impressive 1450 MB/s, and the 480GB at 800 MB/s. This makes them exceptional for clearing camera buffers quickly, which is critical for burst photography and long takes of high-bitrate video.

Buying Guide: What to Consider When Purchasing Memory Cards for Sony FX2
Choosing the right memory card for your Sony FX2 is paramount to ensuring you capture every cinematic moment without compromise. The FX2 is a data-hungry beast, especially when recording in 4K or even 8K (via oversampling for 4K), and its dual card slots offer flexibility, supporting both CFexpress Type A and UHS-II SD cards. However, not all cards are created equal, and selecting the wrong one can bottleneck your camera’s performance, leading to dropped frames, limited recording options, or slow buffer clearing. For example, while a V60 SD card might work for some modes, a V90 UHS-II card or, even better, a CFexpress Type A card, is essential for high-bitrate 4K 60p and XAVC-I recording. Always remember that the memory card isn’t just a place to store your files; it’s an active participant in your camera’s recording pipeline. Invest wisely!
The Most Important Criteria at a Glance:
- Card Type (CFexpress Type A vs. SD): The FX2 supports both. CFexpress Type A cards are significantly faster and necessary for the highest bitrates and frame rates (like 4K 120p XAVC-I), while V90 UHS-II SD cards are excellent for most other 4K modes and offer better value.
- Speed Ratings (VPG, V90, V60): For video, look for Video Performance Guarantee (VPG) ratings on CFexpress cards (VPG400 is ideal for FX2) or Video Speed Class ratings on SD cards (V90 is highly recommended for 4K, V60 for less demanding work). These guarantee a *minimum sustained write speed*, which is crucial for consistent video recording.
- Capacity: 4K files are enormous! Aim for at least 256GB, but 512GB or even 1TB cards are highly recommended for extended shoots to avoid constant card changes and data offloading.
- Durability & Reliability: Professional shoots can be tough. Look for cards that are shockproof, waterproof, temperature resistant, and X-ray proof. Brands like Sony TOUGH and Angelbird are known for their robust designs.
- Brand Reputation & Warranty: Stick with reputable brands known for quality and customer support. A good warranty (like 3-year or even 10-year/lifetime) can save you a lot of headaches if a card ever fails.
FAQ: Frequently Asked Questions about Memory Cards
Question 1: Do I really need CFexpress Type A cards for my Sony FX2, or are SD cards enough?
While a high-quality UHS-II V90 SD card will handle a surprising amount of the FX2’s recording capabilities, including many 4K modes, CFexpress Type A cards are essential if you plan to shoot in the absolute highest bitrates, such as maximum bitrate XAVC-I 4K, or high frame rates like 4K 120p. They also offer significantly faster buffer clearing and quicker data transfers to your computer, which can be a huge workflow advantage. Think of CFexpress Type A as unlocking the camera’s full, uncompromised potential, while V90 SD cards are a fantastic and cost-effective workhorse for most scenarios.
Question 2: What’s the difference between CFexpress 2.0 and 4.0 Type A cards, and does the FX2 support 4.0?
CFexpress 4.0 is the latest standard, offering roughly double the speeds of CFexpress 2.0 cards (e.g., 1800 MB/s read/write vs. 900 MB/s read/write). The Sony FX2’s Slot 1 technically supports CFexpress Type A 2.0 and 4.0. While CFexpress 4.0 cards will work in the FX2, the camera’s internal recording capabilities might not fully utilize the absolute peak 4.0 speeds for *in-camera* recording as of now. However, the biggest benefit of 4.0 cards is the dramatically faster offloading of footage to your computer, especially when paired with a compatible USB4/Thunderbolt reader. This can significantly speed up your post-production workflow.
Question 3: How does temperature affect memory card performance in the Sony FX2?
High-performance memory cards, especially CFexpress Type A, can generate heat during sustained high-bitrate recording. This is a common characteristic of pushing data at such high speeds. Premium cards like Sony TOUGH and Angelbird AV PRO feature advanced thermal management systems to mitigate this, preventing the card from overheating and throttling performance. While the FX2 itself has robust heat management, using high-quality cards with good thermal properties further ensures stable recording during long takes or in warm environments. It’s an often-overlooked factor, but crucial for reliability!
Question 4: What capacity memory card should I buy for 4K video on the FX2?
For 4K video on the Sony FX2, files can be incredibly large. A 256GB card will allow for several hours of recording in many 4K formats, but if you’re doing long documentary shoots, event coverage, or just prefer to minimize card changes and transfers, I strongly recommend 512GB or even 1TB (or higher) capacities. It gives you far more freedom and reduces the stress of running out of space mid-shoot. Consider your typical shooting day and the bitrates you’ll be using; higher bitrates mean faster data consumption. It’s always better to have too much space than too little!
Question 5: Can I mix different brands or types of memory cards in the FX2’s dual slots?
Yes, the Sony FX2 allows you to use two cards of different brands or capacities, and even different types (CFexpress Type A in Slot 1 and SD in Slot 1 or 2). You can set the camera to record simultaneously to both for backup, relay recording to switch to the second card when the first is full, or record different media types to each. However, you must ensure both cards meet Sony’s recommended minimum speed requirements for your chosen recording format to avoid any limitations or error messages. For critical work, I always advise using two high-performance cards of the same type and speed rating for consistency and maximum reliability.

Conclusion: Our Recommendations for Memory Cards
For your Sony FX2, the choice of memory card isn’t something to take lightly. To truly harness the power of this compact cinema camera, especially for high-resolution, high-bitrate video like 4K 120p or demanding RAW codecs, investing in top-tier CFexpress Type A cards is not just recommended, it’s pretty much essential. Cards like the Sony CEA-G Series TOUGH, Angelbird AV PRO, ProGrade Digital Iridium, Lexar Professional Gold, and OWC Atlas Pro stand out because they offer the sustained write speeds and robust reliability that professional workflows demand. They minimize buffer clearing times, ensure consistent recording without dropped frames, and drastically cut down offload times, getting your footage into your editing suite faster.
For most professional use cases with the FX2, I lean towards the latest generation CFexpress 4.0 Type A cards for their sheer speed and future-proofing, even if the camera doesn’t fully utilize their peak speeds internally just yet. Brands like Angelbird and ProGrade Digital, alongside Sony’s own offerings, deliver the consistent performance and durability needed for demanding productions. If your budget is tighter but you still need high performance, a V90 UHS-II SD card can serve well for many 4K modes, especially as a secondary card. Ultimately, the best card is the one that meets your specific shooting needs, fits your budget, and provides the peace of mind that your invaluable footage is safe and sound. Happy shooting!
