The Sony a6400 may have a few flaws, but given its $900 price point, excellent image and video quality, super responsive autofocus (and EyeAF), and E-mount compatibility, we are very impressed.

To sum up, the Sony a6400 is a very, very likeable camera. It nails colour performance, and teams it up with great AF tracking, good ISO performance and great dynamic range. Video performance is its strength, and even in photography, the Sony a6400 more than holds its own ground.

If you have a 6500 and a 6300, should you upgrade to this one? No. Because you are getting the same image quality. If you want a good and affordable second camera for your film projects or are looking to upgrade from a phone or just want to switch to the Sony system, sure give this camera a shot.
