With an APS-C CMOS sensor with 24.2 MP resolution, the Sony Alpha a6400 mirrorless digital camera takes imaging far beyond the capability of a DSLR. However, if you want the best performance out of your camera, then you must use it with an SD memory card that’s fast as well as reliable, especially if you’re looking to shoot videos with your camera.

There are a large number of brands and different models of SD cards available on the market. So much so that you might get overwhelmed and confused while selecting the best one for your camera. To make the whole process easy for you, I’ve come up with a list of the few best Sony a6400 memory cards available on the market today!

Are you ready? Let’s dive in!

 

Sony a6400 SD Card: Specifications


First things first, let’s discuss the specs of the SD card supported by the Sony a6400. The Sony a6400 has a single SD card slot that supports UHS-I SD cards. According to Sony, you can use any SD card that’s Class 4 or above with the camera.

But, upon practical use, I discovered that a minimum Class 10 rated SD card would work best with your a6400 if you want to truly unleash its true potential. Regarding size, a minimum 64GB SD card is recommended. And, if you don’t want to run out of memory space quickly, consider using a 128GB (or larger) SD card.
