That was 5 of the best sd card for sony a7iii for slot 2 UHS-I memory cards.

Best Memory Cards 4k Video Sony A7III

BEST MEMORY CARDS 4K VIDEO SONY A7III
BEST MEMORY CARDS 4K VIDEO SONY A7III

Depending on the Sony camera such as the a7 iii, shooting 4k video can require certain minimum specs.

Aside from a few random cards not working in the Sony A7 III (like Samsung), you should use a U3 memory card to shoot 4k video with the Sony A7 III.

Sony upgraded its firmware in 2016 so that you can now use SDHC memory cards for 4k video, however, you still need to use U3 memory cards.

U3, v30, v60, v90 card memory rated sd cards

In 2016, Sony updated its firmware so that you can now use SDHC 4k video memory cards, but you do need to use U3 memory cards or higher.

Any U3, v30, v60, v90 card rated memory cards will work perfectly for shooting 4k video. 

I would suggest a card like the Sony SF-G UHS-II for shooting 4k video on the sony a7iii.

What Size Memory Card For Sony A7III

A memory card with a minimum capacity of 64GB is recommended for still shots.

This should get you about 3500 photos in JPEG Extra Fine mode, 1750 photos when shooting RAW & JPEGs, 2400 photos in RAW mode only, 1000 in RAW & JPEGs (Uncompressed RAW), 1200 when shooting Uncompressed RAW images.

For filming, especially filming in 4k resolution it is recommend to get 128GB Cards

What memory cards does the Sony A7 III use

You’d better get a UHS-II SD card for optimum use of a7 III. Sony’s newly launched SF-G UHS-II Tough SD card is actually the quickest & toughest UHS-II SD memory card, with the fastest read speed at 300 MB/s and write speed at 299 MB/s. Both the Lexar Professional 2000x UHS-II SDXC and SanDisk Extreme PRO UHS-II SDXC cards have the same peak read rate of 300 MB/s and 260 MB/s write speed.

Which Memory Cards Does The Sony A7 III Support?

The Sony a7iii comes with two memory-card slots, Slot 1 and Slot 2.

Slot 1 supports SD/SDHC/SDXC UHS-I and UHS-II memory cards.

However, for slot 2 – SD/SDHC/SDXC UHS-I are supported.

NOTE: UHS-II cards would work just fine in slot 2 but you won’t be able to take advantage of the speed, as the cameras will default back to UHS-I speeds.

If you have the correct adapter, you could also use microSD memory cards with the sony a7iii

UHS-I vs UHS-II

UHS-I vs UHS-II
UHS-I vs UHS-II

Although the Sony A7 III takes advantage of UHS-II memory cards, depending on how you use slot 1 and slot 2 with recording modes, speeds are bottlenecked to the slowest memory card in the frame.

Appearance

There are two ways to tell a UHS-I card from a UHS-II card.

The first is clear: check the label or packaging. They will either say UHS-I or UHS-II, or be marked with I or II.

It usually uses Roman numerals, but you’ll sometimes see it written incorrectly with a 1 like UHS-1.

You also can tell them apart by looking at the cards. UHS-I cards have a single row of pins on the back. UHS-II have two rows.

Compatibility

The UHS standards enable devices to be backwards-compatible. That means that you can use a UHS-II card in a device that’s compatible with UHS-I and vice versa.

However, if you do this, you will be limited to UHS-1 spec, which is standard for MicroSDHC. That is the general idea, at least.

However, it gets a little more tricky because some devices that support the UHS-1 standard fall back to a slower UHS-1 mode, while better devices that support the standard called SDR104 fall back to it gracefully.

Unfortunately, the features and capabilities of that particular part of the card are rarely specified on either the packaging or in the technical specifications.

Speeds

The UHS-I cards have transfer rates up to 104 Mb/s. An upgraded version, the UHS-II cards, have a transfer rate of 312 Mb/s.

In March 2017, UHS-III specification was announced, doubling previous UHS-II speeds with insane data transfer speeds up to 624 Mb/s.

What memory card should I use for 4k video on a Sony A7III?

Sony upgraded its firmware in 2016 so that you can now use SDHC memory cards for 4k video, however, you still need to use U3 memory cards.

Quick Summary

The a7III gets an awful lot of things just right for generalist photographers. A memory card with a minimum capacity of 64GB is recommended for still shots.

Aside from a few random cards not working in the Sony A7 III (like Samsung), you should use a U3 memory card to shoot 4k video.

In 2016, Sony updated its firmware so that you can now use SDHC 4kVideo memory cards, but you do need to use U3 Memory cards or higher.

The Sony a7ii comes with two memory-card slots, Slot 1 and Slot 2. Slot 1 supports SD/SDHC/SDXC UHS-I and UHS-II memory cards.

However, for slot 2 – SD/ SDHC/ SDXC UHS-I are supported.

The UHS standards enable devices to be backwards-compatible. We recommend going with the Sony G or Sony G Tough cards, but we have had success with Transcend and Toshiba cards.

Best Memory Card For Sony A7III – Bottom Line

We recommend going with the Sony G or Sony G Tough cards, but we have had success with Transcend and Toshiba cards as well.

Stick with U3 when using UHS-I cards so that you can still capture video and stop Samsung and you’ll probably be free of any issues.

By recording simultaneously to both slots 1 and 2, the write speed is restricted to the maximum write speed of the UHS-I card in slot 2. So you can take advantage of these savings by using UHS-I SD cards in slot 1.

If you will be recording RAW files to one slot and JPEGs to another, then this will also be slower than writing to a single card.

However, there is still an advantage for shooting uncompressed RAW to slot 1 and JPEGs to the second slot.

There is no benefit to using a UHS-II card in slot 1 if you shoot RAW to slot 1 and JPEG to slot 2.

It doesn’t always come down to in-camera write speed.

However if you are always impatient waiting for files to be transferred to your device from your SD cards, then you might still want to go for the faster UHS-II cards simply for faster reading speeds.
