The biggest issue users might have with this card over similar options is the price. It’s one of the more expensive options, but it’s worth the extra cash if you’re after the top of the top.

The small item is fully shock, water, temperature, and x-ray proof. That ensures you won’t have to worry about using it no matter where you like to shoot. SanDisk is one of the best brands on the market, and this shows why they’re so respected.

As with the above model, this card is on the expensive side. Know that going into the purchase. Also be aware that this will only work in one of the A7III’s slots.

The Verbatim Pro Plus is a strong card for users with a large focus on toughness. This card can handle just about anything you throw its way. It’s water-resistant, shockproof, and temperature-proof. That trifecta gives it a level of durability you won’t find in similar models.

On top of that impressive shell, the card has pretty strong read and write speeds. It’s also quite powerful. The item is compatible with the second slot in the A7III (something you won’t find everywhere) and it’s not too pricey either.

Just be aware that, while the more expensive versions of this card have larger storage capacity, the more affordable ones are a bit more cramped. Do your research before getting the one for you.

4. Lexar Professional 1066X

  • Best For: Power
  • Key Features: UHS speed class 3. Video speed class 30. Works with Full-HD and 4K UHD images. Lexar Recovery Tool.
  • Memory Type: SDXC
  • Hardware Interface: SDHC
  • Speed Class: 10

Rated with an impressive UHS Speed Class 3 and Video Speed Class 30, the Lexar Professional 1066X is a powerful SD card that’s perfect for the A7III. This model has some of the best performance around, delivering a durable option with long-lasting capabilities.

It comes with UHS-I technology, and is made to survive harsh conditions. It handles all photo qualities and 4k video without any issues too. On top of that, it also includes a Lexar Recovery Tool just in case you lose any data that you need to get back.

This card’s biggest drawback is that it can become overloaded with too much stress. While the shell is strong, it might not have the longevity that you’ll see in other premium SD cards.

5. Sony M-Series SDXC

  • Key Features: Water and dust proof. Memory card case. 10 class speed. Included file rescue software. 260MB/s read speed.

The M-Series SDXC is a card that you can depend on to read and write all of your videos and high-quality photos. It comes with solid speeds (U3, Class 10) and transfers better than almost any other device. That’s especially useful for people who need to work with a lot of data quickly.

In addition, this is both waterproof and dustproof. The included case is another nice touch that adds to the general durability and makes it easy to carry around. There’s also File Rescue Software (available through a download) just in case you lose something.

This card does have decent protection from the elements, but it’s not as durable or as long-lasting as similar Sony A7III models. Know that if you plan on using it in rougher environments.

6. Prograde Digital SD

  • Best For: Budget
  • Key Features: Fast write speeds. Advanced recovery pro software. V60 video speed class. Laser-etched serial numbers. Affordable.
  • Memory Type: SD
  • Hardware Interface: SDXC
  • Speed Class: 10

Many SD cards that work well for the Sony A7III tend to be on the expensive side. The Prograde Digital SD breaks from that trend by giving you a lot of excellent specs without costing an arm and a leg. It’s much more affordable but still reads, transfers, and writes quite well.

The model also comes with special laser-etched serial numbers that add more security. There are two different storage options too, going up to 128GB if you don’t mind paying a little extra. As with other choices, you also get Advanced Recovery Pro software.

The only hitch here is the durability. This does not come with the slew of protections like similar models. Be aware of that if you’re someone who likes to shoot in rougher areas, or if you’re more cavalier with your devices.

Best SD Card for Sony A7III: What to Consider in 2022

Storage Capacity

The entire reason to have an SD card inside your camera is to give you more storage capacity. In the early days of digital cameras, these cards were often only built with 8GB to 16GB of storage. Now, you can get a card that can hold much more. In fact, some go all the way up to 256GB.

Increased storage capacity does correspond with an increase in price, however. While it’s always nice to have large amounts of storage, if you’re on a budget you can get a 32GB or 64GB card without losing too much. You only need a ton of room if you take a lot of photos or like to travel often.

UHS-I or UHS-II

Something else you need to consider when getting an SD card for your Sony A7III is that it has two different slots to hold two SD cards. However, those slots are not both compatible with every type of card. Slot one can handle both UHS-I and UHS-II cards, but slot two only works with UHS-I cards. UHS-I cards are slower and cheaper while UHS-II cards cost more but have faster read and write speeds. You’ll need and want both for the Sony A7III.

Durability

You should also consider your SD card’s durability. Photography will often take you outdoors into remote or extreme situations. With that in mind, you want your gear to be dust, water, and crush proof. All of the cards found here have that durability to ensure you get great results no matter where you go.

Useful Tips & Resources

Even though you might end up with an SD card that offers quite a bit of storage, it’s still always a good idea to back up all of your photos and videos. That can be as easy as placing the SD into a slot on a computer and uploading the data. Here’s a quick video showing you how to backup your SD card onto a computer in case you are unfamiliar with the process.

Final Words

Any way you look at it, you need an SD card for your camera. When it comes to the Sony A7III, you’ll need two. Any of the options listed here will more than meet your needs as they have excellent traits to make your photography much more enjoyable.
