Sony A7r Three | The Speed Test
I've tested every card in the Sony A7r Iii using uncompressed RAW. I've taken the fastest speed out of 3 tests unless the card showed mix results, in that case I took the boilerplate. The only bill of fare that was wild was the PNY U3.
I've as well tested a few cards using Compressed RAW. I've found the speed is slightly faster, about 10MB/s for the UHS-II cards. I'll update the list with those results too in the future.
For the 4k video test I shot on each card for nigh thirty seconds to a minute to make certain the cards weren't rejected past the camera. Usually Samsung cards never work for 4k video in Sony cameras, even so this fourth dimension a few cards worked. I still would avoid Samsung cards but to exist safe.

Sony A7rIII All-time Retentivity Cards
Sony cameras take always been finicky with retentivity cards and there is a long history regarding which cards volition work and which cards will likely not work. Here are the Elevation five memory cards y'all should consider for your Sony A7rIII.
This will probable exist the aforementioned for the up coming Sony A7III and the Sony A7sIII.
Sony A7r III Top v Retentivity Cards
The Sony A7rIII has 2 memory card slots but only i takes UHS-II cards. So you tin either purchase both UHS-2 cards and not worry about mix and matching, or save yourself some money and buy a UHS-I card for the UHS-I slot.
UHS-Ii by default volition be the fastest memory card for your Sony A7rIII equally long as you stick with the top performers.
For UHS-II retentivity cards likewise consider the Delkin and Toshiba cards.
Sony 64GB UHS-II M
This is Sony's latest UHS-Ii card and information technology'due south fast. Definitely as good equally the Sandisk Extreme Pro UHS-II or even the Lexar 2000x. I highly recommend this card for the Sony A7rIII. Sony brand cards near never take compatibility bug with 4k video recording.
– Amazon
Sandisk 64GB UHS-Iii 300MB/s
Sandisk is the next runner-upwardly. They've always made the all-time cards and yous tin never go incorrect with going Sandisk. The UHS-Ii Sandisk Extreme Pro is commonly the fastest menu when tested simply the Sony 1000 and the Lexar 2000x are always shut, sometimes slightly faster.
– Amazon
Lexar 64GB UHS-2 2000x
Lexar was the original best UHS-Ii memory carte du jour but the company may be going away eventually. Some of their cards have already been discontinued and they'll probable get more than and more than difficult to find. So although the 20000x is an amazing card, for future and warranty purposes, we just don't know what's going to happen. I list them anyhow merely considering the card reader they come up with is nice.
– Amazon
Sandisk Extreme Pro UHS-I U3
For UHS-I cards the Sandisk Farthermost Pro has always been amazing and is a very reliable bill of fare for Sony cameras. This is really what I utilize to use in my Sony A7r and A7rII.
– Amazon
Sony 64GB UHS-I U3
The Sony 64GB U3 retentiveness bill of fare definitely isn't the fastest UHS-I bill of fare, but there were a lot of problems with memory cards not beingness uniform with Sony cameras, especially when shooting video. And so this carte become one of my tiptop 5 memory cards and is a safe bet.
– Amazon
Other Cards To Consider / Cards To Avoid
There are a few new brands out there that are making UHS-2 retentivity cards like Hoodman Steel, Adata and even Fujifilm and they are all are dandy options if you tin can notice them at a less expensive price. I've as well had peachy success with Delkin cards in Sony cameras and they also brand a few nice UHS-2 cards.
For a while a lot of people were buying PNY cards because they were such a bang-up price. My PNY cards always piece of work well, but there have been a lot of reported issues of them non working correctly in Sony cameras.
Where To Buy Cards For The Sony A7rIII
A lot of people who read this blog don't have easy access to Amazon and are left with some pretty limited options equally to where they tin can buy retentiveness cards, so for those people and even people here in the Usa, there are a few things you should consider earlier buying memory cards.
Commencement, don't buy memory cards from sources that you don't trust. Be careful of Ebay, there are a lot of apocryphal cards out there. Amazon in the terminal few years has also had some issues with counterfeits cards but they usually stay on meridian of that. With Amazon yous tin can e'er buy from the manufacturer directly or through a trusted store and you'll be less likely to become annihilation counterfeit.
You can always trust my friends over at BHphoto and Adorama. Both corking companies and they will really do a good job of taking intendance of you if something does go wrong. In that location are a few other large camera stores that will accept care of you every bit well.
Avoid small ma and pa camera stores. A lot of times these ma and pa camera stores volition buy some cards in majority off Ebay and then mark them up and sell them in stores. Yous just don't know what you're getting with them. I see people lodge through my site sometimes 50+ cards at a time which leads me to believe they are reselling them somewhere else with a markup.
What to do if you lot get a bad card, or your card isn't working
I've seen so many people who accept had trouble with cards over the years and it always comes downward to a few things.
Start they got a apocryphal card considering they bought it off Ebay.
Sometime manufacturers accept bad production runs. Nobody is immune to this. Lexar had a bad year last year and put out a lot of bad cards.
Some cameras don't like some cards. Sony cameras don't similar Samsung Cards. I've fifty-fifty had a few issues with Transcend cards in a few Sony RX10 cameras where they would give me corrupted blue frames.
I've personally had issues with dingy cards; they would perform really slow until I cleaned the contacts. Could have been oil smudges or something as simple every bit that.
I've seen people who have cleaved one of the UHS-Two pins in the camera. So if you find yourself only getting UHS-I speeds and y'all're using UHS-II cards in the UHS-II memory card slot, smooth a flashlight into your camera and make sure none of your pins are bent, and obviously never force a card into the slot.
Cards have warranties, usually 3 years to lifetime. Y'all can ever call in for a replacement. Or, if yous've but had the card for a month, y'all can return it to Amazon. Most cameras stores will actually accept back cards from my experience.
UHS-Ii vs. UHS-I Retentivity Cards In The Sony A7rIII
Sometimes people get confused on how the buffer works in the Sony A7rIII and and so I'll clarify here. The Sony A7rIII has just one slot that is UHS-II compatible. If you shoot backup to the UHS-I card, you memory bill of fare write speeds will be significantly cut to the performance of UHS-I.
If you shoot RAW+JPEG, you shouldn't technically get a write speed drop if the JPEGs are going to the UHS-I card because the files are much smaller and the UHS-I card should be able to keep up, however, RAW+JPEG takes a lot more processing power and volition fill the buffer a lot quicker, and so y'all will come across a meaning performance loss in retentiveness card write speeds since the camera has to practise so much more work.
Shooting Uncompressed RAW will make massive files and y'all volition fill your buffer a lot quicker, merely they won't deadening downwards your memory carte du jour write speeds, you lot'll merely go overall less performance from the massive files. And honestly, I've done the tests, and I'll practise the tests over again, there is really no betoken of shooting Uncompressed, it's only not worth the .05% increase you become in image quality in the shadows. Sony just put that in their cameras for the most extreme camera nerds.
Finding The Best SD Memory Cards Sony A7rIII
If you lot don't have access to my site and you demand to purchase a quick memory card here is a great manner to figure out which menu volition work for you or not. Information technology really comes down to which carte du jour will work for 4k video and if you remember this info and you will be practiced to go.
All-time Memory Menu 4k Video Sony A7rIII
Sony upgraded their firmware last year then that you can at present use SDHC memory cards for 4k video, yet you still need to use U3 memory cards. Here is a interruption down of some retention card stats and what all the numbers mean.
Grade 10 / U1 – NO 4k!
Grade 10 and U1 are one in the same. It has to do with minimum write speeds a carte is capable of. A Class 10 or U1 card should be able to sustain 10MB/s write speeds in any state of affairs, sequential or random.
However, 4k will non work here.
U3 – 4k compatible
U3 is the minimum requirement for 4k video. Information technology has a minimum operation speed of 30MB/s. And then under whatever circumstance it will be able to keep upward with the 4k video bitrate demands regardless of whether the menu is fragmented or not.
V30 – 4k compatible
V is the newest rating organization. Information technology also has to do with minimum write speeds. V30 is the aforementioned as U3, 30MB/s. It will also work for 4k video. Typically if a card is V30 it's too U3 and meets Sony'due south requirements.
V60 – 4k uniform
Even faster than V30 is V60. 60MB/southward guaranteed minimum write speeds. The thing is with the V60 and V90, although the cards tin can perform with the guaranteed write speed of 60MB/s information technology doesn't mean the camera can. Usually a memory cards performance is limited past the cameras capabilities.
V90 – 4k compatible
Like V60 this ways minimum speeds of 90MB/south. You generally just encounter this on UHS-Two cards.
UHS-I
UHS-I memory cards take a single row of pins. They typically max out at a speed of around 70MB/s writing in camera. Except most Sony cameras cap out speeds at 30MB/s. The Sony A9 and the A7 Three's should all be able to see this 70MB/s performance cap with the improved bus speeds. Assuming the A7rIII has the same guts as the A9.
UHS-2
UHS-Ii cards are going to be the fastest retentiveness cards for the Sony A7rIII. They accept two set of pins that permit more than data to be written and read at the same time. I believe information technology sort of works as a dual aqueduct, then you lot get 2 lanes of information and twice the speed of UHS-I cards
SDHC and SDXC
SDHC and SDXC accept to exercise with the format of the cards. SDHC is 32-flake SDXC is 64-bit. Anything less than 64GB is going to exist SDHC past default. SDXC is going to be anything 64GB and above. I besides believe you will get a 4GB file limit with SDHC. I'm non certain yet what sort of limits the Sony A7rIII has with SDXC cards or with video recording.
Best Retentivity Cards Sony A7rIII | Bottom Line
If you don't similar the superlative 5 cards I've listed or tin can't get access to them in your expanse, y'all can purchase any cards from the chart that are marked to piece of work. Or send me a comment and I verify whatever card that I have on the listing for you since at that place are so many brands now. Sony has been improving their hardware so hopefully we'll go better retentiveness card compatibility.
Also, if you desire to buy Micro SD cards, they will as well piece of work every bit long every bit they match the aforementioned specs as their SD cards. I merely personally don't like using Micro SD cards because I've had issues with the adapters.
Bottom line – as long as you lot stick with Sandisk and Sony brand cards, you'll likely have no bug.
