How to Choose the Best SD Cards for Sony a7S III?

how to choose the best sd card for sony a7siii

Speed Class

The main speed classes are 10, 6, 4 and 2. The fastest is class 10, which is great for recording full HD videos and filming in HD consecutively. The slowest is class 2, providing enough speed to record video in standard definition only. Classes 4 and 6 are in the middle; they both allow recording video in high definition.

Besides, there are classes 1 and 3, known as UHS (Ultra High Speed), and meant for professional use. These cards are used with devices supporting UHS, and their price is significantly higher.

Warranty

Purchasing an SD card for Sony a7SIII, remember about the warranty. It may be valid for two, sometimes five years, or even during a lifetime. Well-known brands, for instance, Kingston, ensure extended warranty periods, as opposed to their less famous competitors.

Storage Space

Read a user manual of the device you are going to use the card for to check which is the maximum storage capacity it can support. The maximum size of the memory card supported differs for the devices from different manufacturers. For example, a smartphone is compatible with a 256 GB memory card, although an older digital camera can work with only 32 GB. While a laptop is capable of working with a card of 1 TB. Therefore, we recommend ensuring a device can support the size of the card you are going to purchase, not to waste money on the storage you don’t need.

Physical Size

The size of a card also matters. There are standard SD cards, miniSD cards, and microSD cards. Check the size your camera requires before making a purchase, as you won’t be able to use a microSD card if your camera has a standard SD card slot. Nevertheless, there are adapters, allowing you to plug a smaller SD card into a larger slot. We have also picked the best adapters for using a microSD card in a standard card slot.
