What is the best memory card for Sony A7R V?
The Sony A7R V is one of the most demanding cameras on the market. Its 61-megapixel full-frame sensor produces enormous RAW files — uncompressed, a single shot weighs in at around 130 MB.
Pair that with continuous burst shooting or 8K video, and you quickly realize that the wrong memory card can become your biggest bottleneck.
A slow card won’t just hold up your workflow — it will limit which shooting modes you can even access in the first place.
This guide cuts through the noise. Whether you’re a landscape photographer, wildlife shooter, or video creator, you’ll find the right card for your needs here — backed by real-world performance data.
Quick pick: If you want the single best memory card for the Sony A7R V right now, go with the Sony Tough CEA-G160T CFexpress Type A. It’s fast, nearly indestructible, and built specifically for Sony cameras.
Here is the list of top 5 memory card for Sony A7R V:

Understanding the Sony A7R V’s Card Slots
Before diving into specific products, it’s worth knowing what the A7R V actually supports — because getting this wrong means buying a card that simply won’t work.
The Sony A7R V features two memory card slots, and both are dual-format, meaning each slot accepts either CFexpress Type A or UHS-II SD cards. This gives you tremendous flexibility, but it also means you have some decisions to make.
CFexpress Type A is the faster format. Cards in this category deliver sustained write speeds many times higher than even the best SD cards, clearing the A7R V’s buffer significantly faster during burst shooting. Certain video modes — particularly slow motion and high-bitrate formats — require a CFexpress Type A card to even function.
UHS-II SD cards are slower but more affordable and widely available. For photographers who don’t shoot long continuous bursts, a good V90-rated UHS-II card is more than adequate. Landscape, portrait, and travel photographers will likely find UHS-II cards perfectly capable.
One important caveat: if you shoot simultaneously to both slots, your overall write speed is always limited by the slower card in the pair. So if you use a CFexpress card in Slot 1 and a UHS-II SD card in Slot 2, the system writes at UHS-II speeds.
Key Specs to Understand Before Buying
Write speed over read speed — The number printed on the front of most cards is the read speed, which is relevant for transferring files to your computer. What matters in-camera is the write speed, which determines how quickly the camera can dump its buffer to the card. Always check the write speed spec.
Video speed class (V rating) — The A7R V has specific card requirements depending on the video mode. XAVC HS 8K (400 Mbps) requires a VPG200-rated CFexpress or at minimum a V60 SDXC card. Some slow-motion modes require CFexpress Type A outright. V30 and V60 cards will lock you out of certain recording formats.
Capacity — For burst photographers, capacity matters more than you’d think. An uncompressed RAW file from the A7R V is roughly 130 MB; shooting a sustained burst will eat through a 64 GB card faster than expected. For serious continuous shooting, 160 GB or more is recommended.
CFexpress 2.0 vs 4.0 — You’ll see both versions on sale. CFexpress 4.0 cards are backward compatible with 2.0 devices, meaning they work fine in the A7R V — but the camera cannot take advantage of the extra speed. In real-world in-camera testing, 4.0 cards show no performance benefit over 2.0 cards in this body. Don’t pay a premium for 4.0 unless you’re future-proofing for a newer camera.
The 5 Best Memory Cards for Sony A7R V
1. Sony Tough CEA-G160T CFexpress Type A — Best Overall
Verdict: The safest, fastest, most reliable choice for the A7R V — built by the same company that made the camera.
The Sony Tough CEA-G160T is the card most professional Sony shooters reach for when reliability is non-negotiable. With read speeds up to 800 MB/s and write speeds up to 700 MB/s, it clears the A7R V’s buffer as fast as any card available and handles every video mode the camera supports, including the most demanding high-bitrate formats.
What truly sets it apart is its physical durability. Sony’s TOUGH design is not marketing fluff — the card has over 10x greater bend resistance than standard CFexpress specifications, a resin body tested to 150 newtons of force, and an IP57 dust and moisture rating. It can survive drops of up to 24.6 feet. For photographers who work in rain, sand, or cold, this card offers serious peace of mind that a standard card simply cannot.
It also carries VPG 400 certification, meaning it guarantees a minimum sustained write speed of 400 MB/s — enough headroom for even the most demanding video modes.
The trade-off is price. The Sony Tough is one of the more expensive CFexpress Type A cards on the market. But for professional work where losing footage or images is not an option, the cost is justified.

| Format | CFexpress Type A (2.0) |
| Read speed | Up to 800 MB/s |
| Write speed | Up to 700 MB/s |
| Video rating | VPG 400 |
| Capacities | 80 GB, 160 GB, 320 GB, 640 GB |

2. Lexar Professional CFexpress Type A Gold — Best Performance
Verdict: Blazing-fast read speeds and strong sustained write performance at a slightly lower price than Sony’s offering.
The Lexar Gold CFexpress Type A is a top-tier performer that competes directly with Sony’s own card. It delivers read speeds up to 900 MB/s and sustained write speeds up to 800 MB/s, making it one of the fastest CFexpress Type A cards available for the A7R V. In real-world in-camera buffer tests, it performs on par with the Sony Tough, clearing the buffer quickly even during uncompressed RAW bursts.
Like the Sony card, it carries VPG 400 certification for professional video use and supports 8K RAW recording. Lexar also backs it with a 10-year limited warranty and includes access to their recovery software, which is useful insurance for working professionals.
The build quality is solid, though it doesn’t match the full TOUGH spec of Sony’s card — it’s rated for temperature, vibration, and drop resistance, but it lacks the same IP57 water resistance rating. For studio or controlled-environment shooting, that’s unlikely to matter. For adventure or wildlife photographers, Sony’s card edges ahead.
| Spec | Detail |
| Format | CFexpress Type A (2.0) |
| Read speed | Up to 900 MB/s |
| Write speed | Up to 800 MB/s (sustained) |
| Video rating | VPG 400 |
| Capacities | 80 GB, 160 GB, 320 GB |
| Warranty | 10-year limited |
Best for: Studio photographers and videographers who want maximum speed and don’t need extreme weather sealing.

3. ProGrade Digital CFexpress Type A Gold — Best for Video
Verdict: Consistently strong sustained write speeds make this the preferred choice for serious videographers.
ProGrade Digital has built a strong reputation among videographers specifically because of their emphasis on sustained performance rather than peak burst speeds. The CFexpress Type A Gold delivers up to 900 MB/s read and 800 MB/s write, but what makes it stand out is how consistently it maintains those speeds during extended recording sessions.
It comes in 240 GB and 480 GB capacities, which is especially useful for cinematographers shooting long takes in high-bitrate formats — you’re less likely to run out of space mid-scene. VPG 200 certification ensures it meets the requirements for all video modes on the A7R V.
ProGrade also includes their Refresh Pro software with purchase, which allows you to maintain and refresh the card’s performance over time — a small but meaningful feature for users who push their cards hard on a daily basis.
| Spec | Detail |
| Format | CFexpress Type A (2.0) |
| Read speed | Up to 900 MB/s |
| Write speed | Up to 800 MB/s |
| Video rating | VPG 200 |
| Capacities | 240 GB, 480 GB |
| Software | Refresh Pro included |
Best for: Videographers shooting long-form content, documentary filmmakers, and anyone who records extended continuous video.

4. Sony SF-G Tough UHS-II SD Card — Best UHS-II Option
Verdict: The best SD card you can put in the Sony A7R V — if you don’t need CFexpress speeds.
Not everyone needs CFexpress performance. If you’re a landscape, portrait, or travel photographer who shoots deliberate single frames rather than rapid bursts, a top-tier UHS-II SD card will handle the A7R V’s files without issue — and save you significant money in the process.
The Sony SF-G Tough is the gold standard here. It offers read speeds up to 300 MB/s and write speeds up to 299 MB/s, with a V90 rating guaranteeing a minimum 90 MB/s sustained write speed. That’s more than sufficient for most stills shooting and for all standard video modes on the A7R V.
It shares Sony’s TOUGH build philosophy — IP57 rated, rigorously drop-tested, and resistant to temperature extremes, UV, and X-rays. It’s available in capacities up to 256 GB, which is generous for an SD card.
One practical advantage: SD cards work in virtually any computer’s built-in card reader, making file offload simpler and faster without needing a separate CFexpress reader.
| Spec | Detail |
| Format | UHS-II SD |
| Read speed | Up to 300 MB/s |
| Write speed | Up to 299 MB/s |
| Video rating | V90 |
| Capacities | 32 GB – 256 GB |
| Durability | IP57, TOUGH build |
Best for: Landscape, portrait, and travel photographers who don’t shoot rapid bursts and want a simpler, more affordable setup.

5. SanDisk Extreme Pro UHS-II — Best Budget Pick
Verdict: One of the most reliable and popular UHS-II cards available, at a price that makes stocking up easy.
The SanDisk Extreme Pro UHS-II V90 has been a staple recommendation for good reason — it consistently delivers on its performance promises and has earned a strong reputation for reliability across thousands of professional shooters. It delivers read speeds up to 300 MB/s and write speeds up to 260 MB/s, with V90 certification for video stability.
In real-world A7R V buffer tests, the SanDisk Extreme Pro performs very closely to the Sony SF-G Tough at a meaningfully lower price point. The difference in buffer clearing times between the two is marginal for most shooting scenarios.
The card is available in a wide range of capacities from 64 GB up to 1 TB, making it easy to match your storage needs. SanDisk also includes a lifetime limited warranty and access to their RescuePRO Deluxe data recovery software.
It lacks the Sony SF-G’s extreme ruggedness — it has no IP rating — but it’s plenty durable for everyday professional use.
| Spec | Detail |
| Format | UHS-II SD |
| Read speed | Up to 300 MB/s |
| Write speed | Up to 260 MB/s |
| Video rating | V90 |
| Capacities | 64 GB – 1 TB |
| Warranty | Lifetime limited |
Best for: Photographers on a budget who want proven reliability without overspending, and anyone looking for a reliable backup slot card.

Which Card Should You Buy? A Use-Case Guide
For high-resolution photo bursts (61MP RAW files) Go with the Sony Tough CEA-G160T or Lexar Gold CFexpress A. CFexpress Type A cards are significantly faster at clearing the buffer after sustained bursts. If you regularly fill the buffer during sports, wildlife, or action shooting, the speed difference between CFexpress and UHS-II is very noticeable.
For 8K and high-bitrate 4K video The ProGrade Digital Gold is the top pick for sustained recording. Its larger capacities (up to 480 GB) and consistently strong sustained speeds mean you can roll long takes without worrying about dropped frames or running out of space. The Sony Tough is equally capable, just available in smaller sizes.
For travel photographers on a budget The SanDisk Extreme Pro UHS-II V90 is the smart choice. It handles everything the A7R V needs for standard shooting and most video modes, it’s available in large capacities at reasonable prices, and it’s compatible with most laptop card readers without an adapter.
For professional studio and event work If reliability is your top priority, the Sony Tough CEA-G160T is hard to argue against. The combination of extreme durability, VPG 400 video certification, and native Sony compatibility makes it the safest choice when your livelihood depends on not losing files.
Tips for Getting the Most From Your Memory Card
Configure your dual slots wisely. The A7R V offers three dual-slot modes: simultaneous (writes to both cards at once for instant backup), relay (switches to the second card when the first is full), and separate RAW/JPEG recording. For maximum shooting speed, use a single CFexpress card in Slot 1 on relay mode. For critical shoots, use simultaneous recording with two matched cards.
Always format in-camera. Format your cards inside the camera using the menu, not on a computer. This sets up the correct file system for the camera and prevents compatibility issues.
Match your card reader to your card brand. Mixing card and reader brands occasionally causes compatibility issues. If you use Sony cards, use the Sony MRW-G2 reader. Lexar cards pair best with Lexar readers. Also note that even a fast reader is limited by the card’s maximum speed.
Avoid UHS-I cards entirely. The A7R V supports UHS-I cards technically, but they’re far too slow for 61 MP RAW files and will create a serious bottleneck. Always use UHS-II or CFexpress Type A.
Conclusion
The Sony A7R V deserves a memory card that can keep up with its capabilities. For most photographers, one CFexpress Type A card for primary shooting and a good UHS-II card for the backup slot is the ideal setup.

Frequently Asked Questions
Can I use a regular SD card in the Sony A7R V? Technically yes, but you shouldn’t. Standard UHS-I SD cards are far too slow for the A7R V’s large RAW files and will create a significant bottleneck. Always use at minimum a UHS-II V60 card. For serious work, V90 or CFexpress Type A is strongly recommended.
What is the fastest memory card for the A7R V? In real-world in-camera testing, most CFexpress Type A cards perform very similarly. The Lexar Gold and ProGrade Gold edge ahead on paper with 900 MB/s read speeds, but the practical difference during shooting is minimal. Any of the CFexpress Type A cards listed above will clear the buffer as fast as the A7R V allows.
How many 61MP RAW files fit on a 256 GB card? Approximately 800–1,000 uncompressed RAW files, depending on scene complexity. Switching to lossless compressed RAW roughly doubles that number with minimal impact on image quality. For JPEG only, you can store several thousand images.
Is CFexpress Type A worth the extra cost? For burst shooters, action photographers, and videographers shooting high-bitrate formats — absolutely yes. For landscape, portrait, and casual travel photographers who shoot one frame at a time, a good UHS-II V90 card delivers perfectly acceptable performance at a significantly lower price.
Will CFexpress Type A 4.0 cards work in the A7R V? Yes, they are backward compatible. However, the A7R V uses the 2.0 standard, so you won’t see any in-camera speed benefit from a 4.0 card. In-camera performance is identical to a 2.0 card.
