Sony a7 III SD Card Speed Recommendation for 4k Videos


The Sony a7III has two SD card slots numbered Slot 1 and Slot 2.

Slot 1 is known to take in faster UHS-II cards example, Sony SF-G Series for delivering better results. UHS-I cards would also work perfectly well though, no added benefit would be received due to the backward compatibility with UHS-I cards.

Slot 2 which is known as the slower slot, intakes UHS-I cards like Sandisk Extreme or SanDisk Extreme Pro.

The Sony a7III mirrorless camera takes SDXC and SDHC memory cards only.  A point to note here is, that it is not necessary to fill up both the SD card slots. But there are certain advantages to using two cards together.

  • Increased storage
  • Longer hours of shooting without changing cards
  • You can record simultaneously for a mirror backup
  • You can split data into two cards based on filetype

If you record simultaneously to both slots 1 and 2 then the write speed is restricted to the maximum write speed of the UHS-I card in slot 2.

UHS-I or UHS-II refers to the interface that’s used to connect to the cards. Sony a7 III can shoot 4K video with a maximum video bitrate of 100Mbps which is around 12.5 MB/s. Therefore you don’t require the fastest memory cards for 4k video recording. All you need to do is check the specified Speed Class. You can buy any card that has a Class 10, U3 rating, or those rated as V30, V60, and V90. It would be perfect for shooting 4k videos.

Card Size depends on the choice of the user. 64GB SD cards  are fair-sized cards to be used while recording. If you are shooting a lot of continuous bursts then you might want to use 128GB SD cards. Avoid using bigger cards and stick to splitting data among different cards. That way you can be sure of not losing the entire footage in case of any issue.
