Who Should Get This?

If you have a Sony A7III camera, then you need SD cards in order to store all of your images and video footage. One of the best features of this camera is its ability to hold two SD cards. That gives you the ability to store large amounts of data directly in the camera. However, without a couple of quality SD cards, you won’t be able to take advantage of that amazing feature.

If you own the camera, there’s no excuse not to use one of the following models.

Best SD Card for Sony A7III: What to Consider

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.


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.


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.
