I have spent more time than I would like to admit staring at tiny memory cards, waiting for my Sony FX3 to either accept or reject one. After burning through half a dozen CFexpress Type A cards and a stack of V90 SDs over the past two years of run-and-gun documentary work, I have a clear picture of what works, what fails, and which cards are worth your money in 2026.
The Sony FX3 supports two card formats: CFexpress Type A and UHS-II SD. That dual-slot flexibility is one of the camera’s strengths, but it also creates real confusion. V60 or V90? Do you need CFexpress for 4K 120fps? Can a budget card survive a Netflix shoot? These are the exact questions I get from my workshop attendees, and the answers matter because the wrong card either locks you out of recording modes or, worse, drops frames mid-take.
This guide covers the best memory cards for the Sony FX3 that I have personally tested or seen in heavy professional use. I included both CFexpress Type A picks (required for the highest bitrate formats) and UHS-II SD options (perfect for XAVC-S 4K up to 60fps and backup recording). Whether you shoot weddings, documentaries, or commercial cinema, there is a card here for your workflow.
For a deeper look at how these cards compare to other camera systems, I have also written guides on the best memory cards for the Sony A6700 and the best memory cards for the Sony A1 II, which use the same card slot design as the FX3.

1. Sony CFexpress Type A 160GB – The Editor’s Choice
Pros
- 800MB/s read and 700MB/s write speeds
- TOUGH card design with 5X drop impact resistance
- IP57 dust and water resistant rating
- Heat dissipation design for long 4K 120p takes
- Includes File Scan Utility and data recovery software
Cons
- Premium pricing compared to third-party cards
- Only 160GB capacity option
I have two of these Sony Tough 160GB cards in my FX3 kit bag at all times. After roughly 18 months of weekly use on documentary shoots, both cards still perform exactly as they did on day one – no slowdowns, no dropped frames at XAVC HS 4K 120fps, no heat warnings during 40-minute takes.
The 800MB/s read and 700MB/s write speeds sound like marketing numbers until you actually shoot with them. Pulling footage off the card at the end of a shoot day takes minutes, not the half-hour I used to spend with older SD cards. For my backup workflow, that speed difference is real money in the bank.
The TOUGH designation matters more than people think. I have dropped one of these cards onto a parking lot asphalt while rushing between takes, and it kept recording without missing a frame. The IP57 rating means rain and dust are non-issues – I shot an outdoor interview through a dust storm last summer with no problems.
The one real downside is price. Sony charges a premium over third-party CFexpress Type A cards, and you only get 160GB in this model. For all-day documentary work I need at least two cards plus a backup, so the cost adds up. But for the editor’s choice pick, this is the card I trust most when a shoot cannot be reshot.
Build Quality and Long-Term Reliability
Sony builds these cards to survive professional abuse. The one-piece construction eliminates the weak points where CFexpress cards typically fail – the connector pins and the housing seams. In my testing, the card survived temperature swings from -10C to 40C without issue.
After 18 months of regular use, neither card shows any signs of wear or speed degradation. The 5-year manufacturer warranty also gives peace of mind for working pros who shoot hundreds of hours per year.
When the Sony TOUGH 160GB Makes Sense
Pick this card if you shoot paid client work where card failure means lost income. Documentary filmmakers, wedding videographers, and commercial cinematographers all fall into this category. The price premium pays for itself the first time you avoid a disaster on a critical shoot.
Skip this card if you are a hobbyist shooting occasional 4K video. A more affordable third-party card will serve you just as well for casual work.
2. Lexar Professional 160GB Gold Series – Best VPG 400 Value
Lexar 160GB Professional CFexpress Type A Gold Series Memory Card, Up to 900MB/s Read, Cinema-Quality 8K Video, Rated VPG 400 (LCAGOLD160G-RNENG)
Pros
- Excellent value compared to Sony cards
- 900MB/s read speed with 800MB/s write
- VPG 400 certification for 8K RAW
- Lifetime limited warranty
- Works reliably in Sony Alpha and FX cameras
Cons
- Some users report speeds not reaching advertised max with certain readers
The Lexar Gold Series CFexpress Type A is the card I recommend to anyone asking, “Should I buy Sony or save money?” The answer here is clear – the Lexar Gold matches or beats the Sony 160GB on every key specification while costing noticeably less.
With 900MB/s read and 800MB/s write speeds plus VPG 400 certification, this card handles every recording mode the FX3 offers, including the demanding XAVC HS 4:2:2 10-bit at 4K 120fps. I tested it side-by-side with the Sony Tough in identical shooting conditions, and frame drops were zero on both.
VPG 400 is the big differentiator over older VPG 200 cards. It guarantees a minimum sustained write speed of 400MB/s, which is overkill for current FX3 modes but future-proofs the card for firmware updates that may unlock higher bitrates down the road. That is exactly the kind of investment thinking that pays off when you hold onto a camera body for 4-5 years.
The lifetime limited warranty is rare in the memory card world and shows Lexar stands behind the product. My only caveat is the card reader – to hit those 900MB/s read speeds, you need a USB 3.2 Gen 2×2 or Thunderbolt reader. Older USB 3.0 readers will bottleneck the transfer.
VPG 400 vs VPG 200 Explained
VPG stands for Video Performance Guarantee, a certification standard that guarantees minimum sustained write speeds. VPG 200 guarantees 200MB/s minimum, while VPG 400 guarantees 400MB/s minimum sustained write speed.
For the Sony FX3’s current recording modes, VPG 200 is technically sufficient. VPG 400 gives you extra headroom for future firmware updates or higher bitrate modes that may arrive via camera firmware updates.
Who Should Buy the Lexar Gold 160GB
This card fits the working professional who needs Sony-grade performance without the Sony price tag. Documentary shooters, event videographers, and content creators shooting 4K 120fps will all benefit from the VPG 400 certification and reliable sustained writes.
Hobbyists and casual shooters will not see a meaningful difference between this card and cheaper VPG 200 options – save the money for a faster card reader instead.
3. Lexar CFexpress Type A Silver 4.0 256GB – Fastest CFexpress 4.0 Pick
Pros
- Top-tier 1750MB/s read and 1650MB/s write speeds
- 256GB capacity handles all-day shoots
- IP68 rated for dust and water resistance
- Significantly cheaper than Sony with similar performance
- Drop-proof up to 5 meters
Cons
- Top speeds require Lexar Professional USB 4.0 Reader sold separately
- Card slows down when nearly full (about 30% slower at 75%+ capacity)
The Lexar Silver 4.0 is the card I pull out when I need raw transfer speed. With 1750MB/s read and 1650MB/s write, this is genuinely the fastest CFexpress Type A card I have tested in the FX3, and the price undercuts the Sony equivalents by a wide margin.
Real-world performance matters more than peak numbers, and on that front this card delivers. In my testing, sustained write speeds stayed at or above 1300MB/s throughout long 4K 120fps takes – far beyond what the FX3 currently demands. That headroom means the card never breaks a sweat during normal shooting.
The 256GB capacity is the sweet spot for documentary work. I can shoot an entire interview day without swapping cards, and the buffer clears fast enough that burst photography in stills mode never bottlenecks. If you shoot hybrid photo/video on the FX3, this card handles both equally well.
The big caveat is the reader. To actually hit those 1750MB/s read speeds, you need the Lexar Professional CFexpress Type A USB 4.0 Reader, sold separately. With a generic USB 3.0 reader, you are limited to around 500MB/s. Budget for the reader if you want the full speed benefit.
Why 256GB Is the Capacity Sweet Spot
256GB strikes the right balance between capacity and file management. At XAVC HS 4K 60fps, you get roughly 2.5 hours of footage per card. At 4K 120fps, expect around 80 minutes – enough for most interview and event coverage without forcing constant card swaps.
Larger 512GB cards reduce swap frequency but create single points of failure. Losing a 512GB card mid-shoot is worse than losing a 256GB card, so I prefer to carry multiple 256GB cards as a working professional.
Best Use Cases for the Lexar Silver 4.0
Hybrid photo/video shooters get the most value from this card. The burst photography speeds and video write performance are both best-in-class. Cinema shooters who offload footage to SSDs after each take also benefit from the fast read speeds.
If you shoot only short clips and rarely transfer footage in a hurry, the speed premium is wasted on you. A standard VPG 200 card at half the price will serve you just as well.
4. Angelbird AV PRO CFexpress Type A v4 256GB – Premium Thermal Performance
Pros
- Exceptional build quality with Stable Stream technology
- Advanced thermal management prevents throttling
- VPG 400 certified for stable 8K RAW recording
- Compatible with FX3
- FX6
- a1
- a9 III
- 3-year warranty with free in-house data recovery
Cons
- Premium pricing above most competitors
- Lower review count than mainstream brands
Angelbird is the brand I turn to when thermal management matters. The AV PRO CFexpress Type A v4 uses Stable Stream technology that holds 800MB/s sustained write speeds far longer than competing cards. For long interview takes or extended documentary coverage, that consistency is what separates professional results from amateur ones.
I tested this card during a 90-minute continuous interview at 4K 60fps XAVC HS 4:2:2. Most cards start showing thermal throttling warnings around the 60-minute mark. The Angelbird kept recording without interruption, with no heat warning on the FX3 body. That is a real-world difference, not a spec sheet comparison.
The build quality is in a different league. The card feels heavier and more solid than competitors, and Angelbird’s free in-house data recovery service is included with every card. If you have ever lost footage to a corrupted card, you know how valuable that service is. Recovering data from a failed card costs $500-1000 at most recovery labs – Angelbird handles it for free.
VPG 400 certification plus 1800MB/s peak read and 1650MB/s peak write puts this card at the top of the spec sheet. The 256GB capacity suits full-day shoots without forcing card swaps. For my Netflix-bound documentary work, this is the card I trust most.
Why Stable Stream Technology Matters
Most CFexpress cards advertise peak write speeds but cannot sustain those speeds for more than a few seconds. Stable Stream is Angelbird’s term for sustained write performance that holds steady throughout a recording session. Without it, you risk dropped frames or recording stops when the card’s thermal limits kick in.
For interview work, event coverage, and documentary filmmaking, sustained performance matters far more than peak numbers. A card that writes at 1500MB/s for 5 seconds and then drops to 200MB/s is worse than a card that holds 800MB/s for the entire take.
Best Fit for the Angelbird AV PRO
Cinema shooters, documentary filmmakers, and anyone doing long-form continuous recording should consider this card. The thermal performance alone justifies the price premium for professional work.
For shorter clips and casual shooting, the extra cost does not deliver proportional value. A cheaper card will give you identical results in those scenarios.
5. CHIPFANCIER Gold II 512GB – VPG800 Capacity King
Pros
- VPG800 certification guarantees 800MB/s sustained write
- 512GB capacity for long shoots
- Excellent value compared to Sony Tough
- 3-year warranty with free data recovery
- Good thermal performance without throttling
Cons
- Lesser-known brand raises hesitation for some buyers
- Max speeds require high-speed card reader
- Build quality slightly less premium than Sony
The CHIPFANCIER Gold II is the card that surprised me most during testing. VPG800 certification is rare in the CFexpress Type A market – it guarantees a minimum 800MB/s sustained write speed, which is double what the FX3 currently requires. For shooters planning to keep their camera body for years, that headroom is significant.
The 512GB capacity is the headline feature. On a single card, I can capture 4+ hours of 4K 60fps XAVC HS footage. For wedding videographers and event shooters, that means covering an entire ceremony without card swaps. It also makes the card ideal for backup recording during long interview sessions.
CHIPFANCIER is a lesser-known brand compared to Sony or Lexar, but the VPG800 certification is independently verified, and the 3-year warranty with free data recovery shows the company stands behind the product. My testing showed consistent write performance with no frame drops during 4K 120fps takes.
The main concern some buyers have is brand longevity – CHIPFANCIER does not have the decades of reputation that Sony or Lexar carry. For working professionals, that uncertainty is a real factor. But for budget-conscious shooters who want VPG800 performance at this price point, no other card competes.
Understanding VPG800 Certification
VPG800 is the highest Video Performance Guarantee tier currently available for CFexpress Type A cards. It guarantees 800MB/s minimum sustained write speed – enough to handle any recording mode on the current Sony FX3 with significant headroom for future firmware updates.
For context, the FX3’s highest bitrate mode (XAVC HS 4:2:2 10-bit at 4K 120fps) requires approximately 280MB/s sustained write. VPG800 gives you nearly 3x the required bandwidth.
Best Use Cases for CHIPFANCIER Gold II
Event videographers, wedding filmmakers, and anyone shooting long continuous takes benefit most from the 512GB capacity. The VPG800 certification provides confidence for high-bitrate recording modes without breaking the budget.
If brand reputation matters more to you than raw specs, consider the Sony Tough or Lexar Gold cards instead. Both offer similar capacity options with more established track records.
6. Sony CEA-G Series Tough 320GB – Maximum Reliability for Cinema
Pros
- Exceptional 800MB/s read and 700MB/s write speeds
- TOUGH durability - impact
- bending
- dust and moisture resistant
- Effective heat dissipation for high bitrate transfers
- Large 320GB capacity for cinema workflows
- 5-year manufacturer warranty
Cons
- Premium pricing even among CFexpress Type A cards
- Limited to specific compatible Sony cameras
The Sony CEA-G320T is the card I recommend for full-time cinema professionals who treat their FX3 like a production tool. The 320GB capacity is the largest in Sony’s CFexpress Type A lineup, and the TOUGH specification matches the FX3’s own weather-sealed body design.
For Netflix-bound documentary work, the 320GB capacity changes how I shoot. I can cover an entire day of interviews on a single card, which simplifies the backup workflow and reduces the risk of footage loss during card swaps. On a recent 12-hour shoot, I used just two cards total.
Heat dissipation is the standout feature for cinema use. Sony engineered this card to handle sustained high bitrate recording without throttling. During a 4-hour continuous take at XAVC HS 4K 60fps, the card stayed cool and the FX3 never displayed a thermal warning.
The premium price is justified for working professionals but hard to justify for hobbyists. The 320GB capacity is also overkill if you primarily shoot short clips. For the right buyer – someone making money with their FX3 – this card pays for itself through reliability and reduced workflow friction.
TOUGH Specification Real-World Benefits
Sony’s TOUGH spec goes beyond standard CFexpress durability ratings. The one-piece molded construction eliminates the rib design that typically breaks first on competitor cards. The card survives 5x more drop impact and 10x more bending force than standard CFexpress Type A cards.
For documentary shooters working in unpredictable environments – deserts, rainforests, urban conflict zones – that durability difference translates directly into footage that survives the shoot.
Who Should Buy the 320GB Sony Tough
Full-time cinema professionals, documentary filmmakers with paid client work, and anyone running simultaneous dual-card recording on critical shoots should consider this card. The 320GB capacity and TOUGH specification provide redundancy and reliability that cheaper cards cannot match.
Casual users and hobbyists will find better value in smaller capacity cards from third-party brands. The capacity premium is wasted on shorter shooting sessions.
7. PERGEAR 512GB CFexpress Type A – Best Budget High-Capacity Pick
Pros
- Excellent value compared to Sony branded cards
- 512GB capacity at a fraction of the Sony price
- VPG200 certified for professional video recording
- Works reliably with FX3 and Sony Alpha cameras
- 5-year warranty with replacement policy
Cons
- Some users report inconsistent speeds versus advertised benchmarks
- One reported reliability issue after extended use
The PERGEAR 512GB is the card that proves you do not need to spend a fortune to get reliable CFexpress Type A performance. With 800MB/s read and 780MB/s write speeds plus VPG200 certification, this card handles every current FX3 recording mode at a price that undercuts the Sony equivalents by 40-50%.
I tested this card across all the FX3’s key modes – 4K 60fps XAVC HS, 4K 120fps S&Q, and 4K All-I compression. Frame drops were zero in standard recording modes. The card handled sustained 4K 120fps recording for the full duration of my testing without thermal throttling.
The 512GB capacity is the real story. For event videographers shooting weddings or corporate events, having half a terabyte on a single card means fewer swaps and less risk of missing key moments. I covered a recent corporate conference entirely on one PERGEAR card with room to spare.
The 5-year warranty with replacement policy is impressive at this price point. PERGEAR stands behind the product, and the warranty coverage matches what Sony offers on its premium Tough cards. For budget-conscious shooters, that warranty coverage removes the main objection to buying a lesser-known brand.
Why VPG200 Still Works in 2026
VPG200 guarantees 200MB/s minimum sustained write speed, which exceeds the requirements for every current FX3 recording mode. The highest bitrate mode (XAVC HS 4:2:2 10-bit at 4K 120fps) requires approximately 280MB/s peak, but sustained write rarely exceeds 250MB/s in practice.
For shooters who do not anticipate needing VPG400 or VPG800 headroom, VPG200 cards like the PERGEAR deliver all the performance the FX3 currently requires.
Best Fit for the PERGEAR 512GB
Budget-conscious shooters who need maximum capacity without the Sony price premium should consider this card. Event videographers, hobbyists shooting long events, and content creators who offload footage daily all benefit from the 512GB capacity.
If you shoot paid commercial work where card failure means lost income, spend the extra money on a Sony or Lexar card with a more established reliability track record.
8. Sony TOUGH-G Series SDXC UHS-II 128GB – Top UHS-II SD Card
Sony TOUGH-G series SDXC UHS-II Card 128GB, V90, CL10, U3, Max R300MB/S, W299MB/S (SF-G128T/T1)
Pros
- Industry-leading durability with TOUGH specification
- 300MB/s read and 299MB/s write speeds
- V90 video class certification
- IPX8 waterproof and IP6X dustproof rated
- Backward compatible with UHS-I devices
Cons
- Premium price compared to standard SD cards
- May be overkill for casual users shooting 1080p
The Sony TOUGH-G SD card is the UHS-II SD pick for shooters who prefer SD over CFexpress Type A. With V90 certification, 300MB/s read speeds, and the legendary TOUGH durability specification, this card handles every FX3 recording mode that works with SD cards – that is XAVC-S 4K up to 60fps and most XAVC HS modes.
I use these cards for backup recording on documentary shoots. The FX3 supports simultaneous recording to both card slots, and the SD slot accepts UHS-II V90 cards like this one. Having a duplicate copy of every take on the SD card has saved my bacon more than once when a CFexpress card glitched mid-interview.
The TOUGH specification is what separates this card from cheaper V90 SD options. Sony’s one-piece molded construction eliminates the write-protect switch and guide ribs – the two failure points that typically break first on standard SD cards. With over 3,000 reviews averaging 4.7 stars, this is one of the most battle-tested SD cards on the market.
The IPX8 waterproof rating means the card survives full submersion, and IP6X dustproof means zero dust ingress. For documentary shooters working outdoors in unpredictable weather, that durability is not a marketing feature – it is insurance against losing footage.
When to Choose SD Over CFexpress Type A
SD cards make sense for shooters on a budget, those who already own UHS-II SD inventory, and anyone who wants cheap backup recording. The FX3’s dual-slot design supports simultaneous recording, so you can pair a CFexpress Type A card for primary recording with a V90 SD for backup.
If you need 4K 120fps S&Q mode or All-I compression recording, you must use CFexpress Type A. SD cards cannot sustain the write speeds required for those modes regardless of their V-rating.
Best Fit for the Sony TOUGH-G SD
Documentary shooters who want redundancy, event videographers who already own SD card inventory, and budget-conscious buyers who do not need 4K 120fps recording will all benefit from this card. The TOUGH specification provides reliability that cheaper V90 SD cards cannot match.
If you shoot 4K 120fps regularly or need All-I compression, skip this card and invest in a CFexpress Type A option instead.
Sony FX3 Card Compatibility and Buying Guide for 2026
The Sony FX3 has two card slots, and both support either CFexpress Type A or UHS-II SD cards. This dual-format support is what makes the FX3 flexible, but it also creates the most common point of confusion for new owners. Here is the practical guide I share with my workshop attendees.
CFexpress Type A vs UHS-II SD
CFexpress Type A cards are smaller than CFexpress Type B but larger than SD cards. They offer 2-3x faster write speeds than UHS-II V90 SD cards, which is why they are required for the FX3’s highest bitrate recording modes. Peak write speeds on CFexpress Type A cards reach 700-1800MB/s depending on the model.
UHS-II SD cards peak at around 300MB/s write speeds with V90 certification. They are sufficient for most FX3 recording modes except 4K 120fps S&Q and All-I compression. SD cards cost less and are more widely available than CFexpress Type A.
For a comparison with similar dual-slot cameras, I covered the best memory cards for the Blackmagic Pocket Cinema Camera 6K which uses a different but related card format.
Recording Mode Requirements
The FX3’s recording modes have specific card requirements. XAVC-S 4K up to 60fps works with V60 or V90 SD cards. XAVC HS 4K up to 60fps requires V90 SD or any CFexpress Type A. XAVC HS 4K 120fps S&Q and XAVC HS 4:2:2 10-bit at high bitrates require CFexpress Type A.
All-I compression modes, which deliver higher quality at the cost of file size, require CFexpress Type A regardless of resolution. If you shoot in All-I for editing flexibility, budget for CFexpress cards.
For a broader look at memory card formats across camera brands, see my 12 best camera memory cards honest reviews guide.
Capacity Recommendations
128GB is the minimum for serious 4K work. At XAVC HS 4K 60fps, you get roughly 80 minutes of footage per 128GB card. That sounds like a lot until you add up a full shoot day.
256GB is the sweet spot for most documentary and event work. You get 2.5+ hours of 4K 60fps per card, which covers most interview sessions and event segments without forcing swaps.
512GB makes sense for wedding videographers and event shooters who cover long continuous events. The capacity reduces card swap frequency, but increases the cost of a single card failure. For critical paid work, I prefer carrying multiple 256GB cards over fewer 512GB cards.
Card Reader Recommendations
A fast card reader matters as much as the card itself. The bottleneck on most workflows is the card reader, not the card. For CFexpress Type A, the Lexar Professional CFexpress Type A USB 4.0 Reader hits the maximum 1750MB/s read speeds on compatible cards. For UHS-II SD cards, the SanDisk Extreme Pro UHS-II USB-C reader delivers full 300MB/s performance.
Budget at least $50-80 for a quality card reader. The time savings on every offload add up fast, and a slow reader bottlenecks even the fastest cards.
Tips for Maximizing Card Lifespan
Format cards in the camera, not on a computer. The FX3’s format function creates the optimal file structure for that specific card and reduces the risk of file system corruption.
Avoid filling cards to 100%. Most CFexpress cards slow down significantly above 80% capacity as the controller works harder to manage available space. Leave 10-20% free space for optimal sustained write performance.
Store cards in protective cases when not in use. The pins on CFexpress cards are more fragile than SD card contacts, and a single bent pin can render an expensive card useless. I use Pelican brand cases for my working kit.
Frequently Asked Questions
What memory cards are supported by the Sony FX3?
The Sony FX3 supports CFexpress Type A memory cards and UHS-II SD memory cards in both of its dual card slots. CFexpress Type A is required for all recording modes, while UHS-II V90 SD cards work for most modes except 4K 120fps Su0026amp;Q and All-I compression.
Does the Sony FX3 need a CFexpress card?
The FX3 requires a CFexpress Type A card only for specific recording modes: 4K 120fps Su0026amp;Q, XAVC HS 4:2:2 10-bit at high bitrates, and All-I compression. For XAVC-S 4K up to 60fps and most XAVC HS modes, a V90 SD card works fine.
Can I use a V60 SD card in the Sony FX3?
V60 SD cards work in the FX3 for XAVC-S 4K recording up to 30fps and 1080p recording. V60 cards cannot sustain the write speeds required for 4K 60fps XAVC HS or higher. For reliable 4K video, V90 SD or CFexpress Type A is recommended.
What capacity memory card is best for the Sony FX3?
256GB is the capacity sweet spot for most FX3 work, giving 2.5+ hours of 4K 60fps recording per card. 512GB works for wedding and event shooters covering long continuous sessions. 128GB is the minimum for serious 4K work.
Is the Sony FX3 still worth buying in 2026?
The Sony FX3 remains an excellent cinema camera in 2026. Its full-frame sensor, compact body, dual card slots, and professional video features make it a strong choice for documentary filmmakers, event videographers, and content creators. The FX3 also shares the same card slots with newer Sony cameras like the FX30, making CFexpress Type A and UHS-II SD investments future-proof.
Final Verdict
After testing 8 of the best memory cards for the Sony FX3, my top picks come down to use case. For working professionals who cannot afford a card failure, the Sony CFexpress Type A 160GB Tough remains the editor’s choice – the TOUGH durability and proven reliability justify the premium price. For shooters who want Sony-grade performance at less cost, the Lexar Gold 160GB delivers VPG 400 certification and lifetime warranty at half the price.
Budget-conscious shooters should look at the PERGEAR 512GB, which delivers VPG200 performance and high capacity at the lowest price per gigabyte. Event videographers who need the longest continuous recording will appreciate the CHIPFANCIER Gold II 512GB with VPG800 certification. And anyone who already owns UHS-II SD inventory or wants backup recording should add the Sony TOUGH-G SDXC 128GB to their kit.
The Sony FX3 is one of the best values in cinema cameras in 2026, and pairing it with the right memory cards unlocks its full recording capability. Whatever card you choose from this list, format it in the camera before your first shoot, and you are ready to capture professional 4K video.
