The following is a list of the best SD memory cards that are recommended for use in the Sony a7R III mirrorless camera.
Card Slot 1 is compatible with ultra-fast UHS-II SD memory cards, while Card Slot 2 is compatible with slower UHS-I memory cards. The new Sony a7R III comes with two SD memory card slots. A quick UHS-II SD memory card is required if you wish to shoot a 4K video with the Sony a7R III. Without one, you will have to wait much longer for the buffer to clear before you can begin capturing photographs again.
Therefore, investing in a fast card is always a good idea: A rapid write speed ensures a quick clearing of the buffer between burst shots, which improves the overall quality of your shooting experience. The ability to read data quickly allows big files, such as 4K video or a collection of high-resolution photos captured in rapid succession, to be transferred to a PC in a matter of seconds. A friendly reminder, if you intend to capture videos, the greatest video codex will be achieved by using SDXC cards with 64 gigabytes of storage space or more.
We have compiled a list of the top memory cards for use in the mirrorless Sony a7R III camera.
