If you’d like to know which are the best memory cards for the Sony a7 IV and how many shots you can take before hitting the buffer, then you’ve come to the right place.
So far I’ve speed tested 5 CFexpress Type-A cards, 14 UHS-II and 3 UHS-I memory cards in-camera to see how they perform, since in-camera write speeds don’t always match up to what’s on the card label.
This guide should help you to find the best memory cards for your needs and also help you to avoid spending more money than you really need to.

UHS-II SD Memory Cards
These tests were done using my Sony a7 IV and 64GB cards. Unlike the CFexpress cards you will hit the buffer when using UHS-II cards. However you won’t hit the buffer with the fastest UHS-II cards if you shoot in lossless compress raw or jpeg extra fine. See my complete buffer results further down for all the details.

Which Memory Cards are Supported?
The Sony a7IV has two memory card slots, here are the cards that each slot supports:
- Slot 1: CFexpress Type A and UHS-I and UHS-II (SDHC/SDXC) SD cards
- Slot 2: Only UHS-I and UHS-II (SD/SDHC/SDXC) cards
CFexpress Type-A Memory Cards
The Sony a7IV joins both the Sony a1 and the Sony a7SIII by adding support for the faster CFexpress Type-A memory cards. Unlike the a1 and a7SIII however, only one of the memory card slots supports the faster cards.
If you want to shoot in S&Q Mode with the file format XAVC S-I 4k, a record frame rate of 25p / 30p and a frame rate of 50fps /60fps (2x slow motion) then you will need a CFexpress Type A card. The a7 IV will not let you record in this specific format with a V90 card.
Important Note: Please don’t confuse these cards with CFexpress Type-B Cards, these are much larger and are not compatible with the a7IV. Only Type-A Cards are supported in the a7IV.
1. Sony CEA-G CFexpress Type-A
- Max Read Speed: 800 MB/s

Best UHS-II Memory Cards
Thankfully the Sony a7 IV also supports UHS-I and UHS-II (SD/SDHC/SDXC) memory cards in both memory card slots, so you don’t need to spend a fortune on the CFexpress Type-A cards if you don’t really need them.
Here are my recommendations for UHS-II cards for the a7 IV based on my in-camera speed tests using 64GB cards. Please note that when shooting in uncompressed RAW, lossless compressed RAW, uncompressed RAW + JPEG or lossless compressed RAW + JPEG the maximum frames per second is reduced from 10 fps to 6 fps.
1. Kingston Canvas React Plus UHS-II SDXC Memory Card
Kingston have been in the memory business since 1987, so it’s safe to say they know a thing or two about memory!
Their Canvas React Plus UHS-II SDXC cards have a claimed read speed of 300MB/s and a write speed of 290MB/s. They are only a fraction slower in-camera than the Sony SF-G cards (246 MB/s vs 247 MB/s) but they are typically priced around 40% less for a 64GB card and also currently include a UHS-II card reader.
They receive very positive reviews and appear to be just as reliable as the Sony and SanDisk cards. They are V90 rated and available in 32GB (SDHC), 64GB (SDXC), 128GB (SDXC) and 256GB (SDXC) sizes.
In-Camera Speed / Buffer Test Results
When shooting uncompressed raw to slot 1 the in-camera write speed is around 246 MB/s. Here are my in-camera speed test results using a 64GB card and shooting to slot one in Hi+ drive mode.
| Image Type | Shots Before Hitting Buffer | Time to Clear Buffer (Seconds) |
|---|---|---|
| Uncompressed RAW (70.3MB) | 26 | 3.85 |
| Compressed RAW (36.6MB) | 67 | 3.40 |
| Lossless Compressed RAW (40.5MB) | Never hits buffer | < 2.00 |
| JPEG Extra Fine (24MB) | Never hits buffer | < 2.00 |
| Uncompressed RAW (70.3MB) + JPEG Extra Fine (24MB) | 17 | 4.53 |
| Compressed RAW (36.6MB) + JPEG Extra Fine (24MB) | 24 | 4.26 |
| Lossless Compressed RAW (40.5MB) + JPEG Extra Fine (24MB) | 22 | 3.05 |
For the price and performance these are the UHS-II cards that I would recommend for the a7 IV unless you need the toughness of the Sony SF-G cards.
2. Sony SF-G Tough UHS-II
The Sony SF-G Tough cards have a claimed read speed of 300MB/s and a write speed of 299MB/s. They are V90 rated and available in 32GB (SDHC), 64GB (SDXC), 128GB (SDXC) and 256GB (SDXC) sizes.
The Sony Tough series of memory cards are 18 times stronger than traditional SD cards, bend proof to 180N, drop-proof to 5 meters, waterproof to a depth of 5 meters for up to 72 hours (IPX8 rating) and dust proof with an IP6X rating.
Tough cards feature a one-piece ribless structure and don’t have the common lock switch, they are also X-ray proof, magnet proof, anti-static and temperature proof.
I’ve tested these cards in my a7 IV and although newer versions work fine, there are issues with some older versions. Please read the following important note:
Very Important Note: Old versions of these cards do not work with the a7 IV. I get a message that says: “Unable to use Memory Card. Slot 1″. Sony has a replacement program for older versions of these cards due to VSC mode (Video Speed Class) issues where recorded footage on the card may be damaged or may not be recorded optimally. I have three cards that I never got around to sending back that don’t work at all in the a7 IV, but work fine in all of my other Sony cameras. New cards purchased from the second half of 2020 should not be affected, and my cards purchased this year work fine. You can find out if your cards are affected by checking this article.
In-Camera Speed / Buffer Test Results
When shooting uncompressed raw to slot 1 the in-camera write speed is around 247 MB/s. Here are my in-camera speed test results using a 64GB card and shooting to slot one in Hi+ drive mode.

8. Angelbird AV Pro Mk 2 V90
The Angelbird AV Pro Mk 2 V90 UHS-II memory cards support read speeds of up to 300 MB/s and write speeds of 280 MB/s. They are also V90 rated so they guarantee a minimum write speed of 90 MB/s. They are available in 32GB (SDHC), 64GB (SDXC), 128GB (SDXC) and 256GB (SDXC) sizes.
I have tested these cards in my a7 IV for stills and they work fine. For video they didn’t work when the file format was set to XAVC S-I 4K or XAVC S-I HD the first time I used them, but all times after they have worked fine which is a little odd, because as V90 cards they should support these file formats without issue.

10. Sony SF-M Tough UHS-II
Sony’s SF-M Tough Series are similar to the more expensive SF-G version but these are only rated V60 for video and their read time has been cut to 277MB/s and the write time to 150MB/s. They are available in 64GB (SDXC), 128GB (SDXC) and 256GB (SDXC) sizes.
I’ve tested these cards in my a7 IV and although newer versions work fine, there are issues with some older versions. Please read the following important note:
Very Important Note: Old versions of these cards do not work with the a7 IV. I get a message that says: “Unable to use Memory Card. Slot 1″. Sony has a replacement program for older versions of these cards due to VSC mode (Video Speed Class) issues where recorded footage on the card may be damaged or may not be recorded optimally. I have three cards that I never got around to sending back that don’t work at all in the a7 IV, but work fine in all of my other Sony cameras. New cards purchased from the second half of 2020 should not be affected, and my cards purchased this year work fine. You can find out if your cards are affected by checking this article.
In-Camera Speed / Buffer Test Results
When shooting uncompressed raw to slot 1 the in-camera write speed is around 152 MB/s. Here are my in-camera speed test results using a 64GB card and shooting to slot one in Hi+ drive mode.

Memory Card Readers
If you decide to purchase a CFexpress Type-A card or a UHS-II card, then you will also need a compatible memory card reader unless you connect your a7 IV directly to your computer. Here are some of the options available.
Sony MRW-G2 CFExpress Type-A Card Reader
The Sony MRW-G2 supports both CFexpress Type A cards as well as a SD/SDHC/SDXC cards, along with transfer speeds of up to 10 Gb/s via USB 3.1 Gen 2. Both USB Type-C to Type-C and USB Type-C to Type-A cables are included.
ProGrade Digital CFexpress Type A & UHS-II SDXC Dual-Slot USB 3.2 Gen 2 Card Reader
The ProGrade Digital reader has basically the same specs as the Sony MRW-G2 reader but comes at a cheaper price. It has one CFexpress Type A slot and one UHS-II SDXC slot, and also support up to 10 Gb/s via USB 3.2 Gen 2 to deliver transfer speeds of up to 1.25 GB/s, or 1250 MB/s via its USB Type-C interface. It includes USB Type-C to Type-C and Type-C to Type-A cables.
Sony MRW-S1 UHS-II USB Memory Card Reader/Writer
The Sony MRW-S1 UHS-II USB SD Card Reader/Writer can read/write to UHS-II SD Cards via a USB 3.1 interface and is backward compatible with UHS-I SD cards. The Sony MRW-S1 used together with Sony SF-G cards will transfer files to and from your computer around 2.6x faster than UHS-I SD cards.
Kingston MobileLite Plus USB 3.2 SDHC/SDXC UHS-II Card Reader (MLP)
This UHS-II SD card reader features a fast USB 3.2 Gen 1 interface and supports both UHS-II and UHS-I cards.
Memory Cards for Recording Video
The Sony a7IV supports a number of different movie recording formats. The format that you choose to record in will determine the memory cards that you use. Here’s a list or supported recording formats and compatible memory cards for the a7IV.
Memory Cards for S&Q Motion Shooting
Here you can find a list of supported recording formats and compatible memory cards for S&Q motion shooting with the a7IV.
You will only require a CFexpress Type-A card when shooting in S&Q Mode with the file format set to XAVC S-I 4k, a record frame rate of 25p and a frame rate of 50fps (2x slow motion).
*1 When [Rec Frame Rate] is set to [30p]/[25p]/[24p], [Frame Rate] is set to [120fps]/[100fps], and the recordable bit rate is set to 50 Mbps, an SDXC card (V60 or higher) or a CFexpress Type A memory card (VPG200 or higher) is required.
*2 When [Rec Frame Rate] is set to [30p]/[25p]/[24p] and [Frame Rate] is set to [60fps]/[50fps] for slow-motion recording, a CFexpress Type A memory card (VPG200 or higher) is required.
What Size Memory Card Do You Need?
If you will be shooting a lot of continuous bursts then you will probably want to use at least a 128GB card. For CFexpress you can only choose between 80GB and 160GB right now.
If you are not shooting long continuous bursts then you’ll probably be fine with 32GB or 64GB cards, and you certainly won’t need the faster CFexpress Type A cards.
For shooting video the size of memory card will depend largely on the format that you are recording in. Or you may be using an external recorder anyway so this won’t be so important.
I’d recommend only using SDXC cards and not SDHC. 32GB cards and smaller are SDHC and use the FAT32 file system. If you shoot video with a SDHC card your files will be split into 4GB chunks which creates extra work in post production.
The following tables will help you to better understand what size cards you need.
How Many Images Can Be Recorded on a Memory Card?
The table below shows the approximate number of images that can be recorded on a memory card formatted in the a7IV when using a Sony memory card with the aspect ratio set to 3:2 and JPEG/HEIF size set to L:33M.
The values may vary depending on the shooting conditions and the type of memory card used.
Movie Record Times
The table below shows the approximate total recording times using a Sony memory card formatted in the Sony a7IV. The values may vary depending on the shooting conditions and the type of memory card used.
Simultaneous Recording Slot 1 + Slot 2
If you want to record simultaneously to both slots 1 and 2 at the same time then there is no benefit to using a CFexpress Type-A memory card in slot 1.
With this setup the write speed is restricted to the maximum write speed of the UHS-II card in slot 2. So if you shoot like this often you can save money by using UHS-II cards in slot 1 instead of CFexpress Type-A.
The only benefit to using a CFexpress Type-A card when shooting simultaneously is to enjoy the faster read times when copying the files to your computer.
Providing you are using identical UHS-II cards in both slots then the number of shots that you can take and the buffer clearing time will be the same as writing to a single slot. If one of the UHS-II cards is slower then you will be limited to the speed of that card.
Sort RAW / JPEG
You can also setup your a7 IV to record RAW files to slot 1 and JPEG files to slot 2, there is still a benefit to using a CFexpress card with this setup.
If you use a CFexpress Type-A card in slot 1 then providing you record either uncompressed or compressed raw to slot 1 and JPEGs to slot 2, you will never hit the buffer when shooting continuously. However, you must be using one of the faster UHS-II cards in slot 2 like the Kingston Canvas React Plus UHS-II or Sony SF-G Tough cards. Slower cards like the Sony SF-M cards will cause the buffer to be hit.
If you use UHS-II cards in both slots and want to shoot uncompressed or compressed raw to slot 1 and JPEGs to slot 2 you will hit the buffer after around 26 shots (uncompressed raw) or 67 shots (compressed raw).
Dual Card Setup Guide
If you are not sure how to setup dual card recording with the Sony a7 IV then you might find my short video guide helpful.
Summary
If you shoot a lot of continuous bursts and want the buffer to clear as fast as possible, then you’ll want to use a CFexpress Type-A card in slot one.
All of the CFexpress Type-A cards tested so far perform very well in-camera. The Sony CEA-G, Prograde, Delkin and Lexar cards all allow you to shoot with all file types including Compressed RAW + JPEG Extra Fine without ever hitting the buffer.
The Exascend and Pergear cards are a little slower when shooting Compressed RAW + JPEG Extra Fine, but these cards are also a lot cheaper and much better value.
I’m expecting the Angelbird AV Pro CFexpress 2.0 Type A (1TB) to perform well when I’m able to test this card, and I expect the Sony CEA-M Series will also perform well.
For a UHS-II card I’d recommend the Kingston Canvas React Plus UHS-II SDXC. They are only a fraction slower in-camera than the Sony SF-G Tough cards (246 MB/s vs 247 MB/s) but they are typically priced around 40% less for a 64GB card.
If you want to shoot in S&Q Mode with the file format XAVC S-I 4k, a record frame rate of 25p/30p and a frame rate of 50fps /60fps then you will need a CFexpress Type A card. The a7 IV will not let you record in this specific format with a V90 card.
Alternatively you could record in one of the none S&Q video formats such as 4k60 XAVCS and then interpret the footage in post. Of course you won’t be able to view the S&Q footage in camera and this is an extra post processing step, but now you won’t require a CFexpress card and you’ll also get audio since recording in S&Q disables the audio.
If you shoot a lot of continuous bursts in uncompressed raw format then you will hit the buffer when using the Kingston or Sony SF-G UHS-II cards after only 26 shots, but it clears in 3.85 seconds so it’s rarely an issue. With compressed raw you’ll hit the buffer in around 67 shots. If you shoot JPEGS you’ll never hit the buffer. You’ll need a CFexpress card if you don’t want to hit the buffer shooting compressed or uncompressed raw.
If you have some of the older Sony SF-M series, SF-M series TOUGH specification, and SF-G series TOUGH specification SD cards, you might find that they don’t work at all in the a7 IV I’m afraid. There is a replacement program running for these cards due to a different issue, so I’d suggest replacing them before it expires on Mar. 31, 2022.
It would be good to hear about what cards you are using in your own a7 IV and whether or not you have run into any problems with them. Let me know in the comments below.

Thanks Timothy for great contest and all your efforts for this website.
I’m wondering how the Kodak UHS-II v90 performs comp[are to other brands you tested.
If you can add that test results for that which has resonably priced for a V90 memory that would be awesome!
Thanks Ehsan. I’ve not tested the Kodak UHS-II v90 so can’t comment on its performance I’m afraid. I will look into adding it to my future tests though.
Has anyone experienced significant lag when trying to review photos on uhs-ii cards? I purchased a used a7iv that works perfectly, except for a 3-6 seconds lag when trying to review pictures as well as switching back to photo mode from preview mode. I’m wondering if I was sold a lemon.
Did you resolve this Jesse? Try changing your Auto Review settings. MENU → (Setup) → [Display Option] → [Auto Review] → desired setting. Personally I prefer it turned off.
