Best SD Cards for Sony A6400

Sony A6400 is the first mirrorless camera to be released in 2019 and is essentially an update to the A6300, which is now three years old. As you may have guessed it, it shares a lot of features with its older brother like the 24MP sensor, 4K video recording at up to 30fps and 1080p recording at up to 120fps. However, the A6400 offers a lot of useful updates as well, including even better Eye Autofocus, Animal Eye-AF, as well as real-time object tracking.

The camera also comes with an intervalometer that allows you to shoot time-lapse videos and a flip-up screen, which makes the Sony A6400 one of the best vlogging cameras of 2019. With the overview of the camera’s features out of the way, let’s take a look at some of the best SD cards for Sony A6400.

Best SD Memory Cards for Sony A6400

Just like the A6300 and A6500, the new camera also supports UHS-I SD cards, which means you don’t need to purchase pricier UHS-II cards. Being that this is Sony’s new entry-level mirrorless camera, it makes sense they are not supporting UHS-II memory cards, a feature that is for now reserved for their full frame camera bodies. If you want to future proof your purchase and don’t mind the extra cost, feel free to go with UHS-II memory cards, as they are backward compatible and will be useful if you’re upgrading to a more high-end camera in the future. Otherwise, you can just go with UHS-I cards. With that said, here are our suggested SD cards for the A6400.

Recommended SD Cards for 4K Video on A6400

If you plan on recording 4K video with your Sony A6400, you have to make sure that your SD cards are compatible. All SD cards from our list above will be able to handle A6400’s 100 Mbit/s (12.5 MB/s) 4K codec with ease, but if you have some older SD cards laying around, you have to make sure that they are U3 capable (there’s a tiny sign on the memory cards itself, usually). If you want optimal performance, we suggest buying one of the aforementioned UHS-I cards.
