Released in 2019, the a6400 became one of the most widely recommended APS-C cameras for content creators and vloggers specifically because of its flip-up rear screen and genuinely fast autofocus in a compact, relatively affordable body — a combination that made it a default recommendation well beyond its original still-photography target audience. Its real-time Eye AF and subject tracking were genuinely ahead of most competing APS-C bodies at launch, a major reason it became a default recommendation for vloggers and content creators well beyond dedicated still photographers. Its 0.02-second autofocus acquisition speed was a genuinely class-leading figure at launch, and the combination of that speed with real-time Eye AF made the a6400 feel meaningfully more responsive in everyday shooting than its modest price point suggested. A genuinely notable achievement for its price class.

Sony also gave the a6400 a then-new touch-tracking autofocus interface, letting photographers simply tap the screen to lock focus and track a subject through a moving scene.

Frequently Asked Questions
Why does the a6400 lack in-body stabilization when the a6600 has it?
Sony positioned the a6400 as a smaller, lighter, less expensive body within the same generation, and omitting in-body stabilization was one of the deliberate cost and size tradeoffs — many a6400 owners rely on stabilized lenses, gimbals, or simply faster shutter speeds instead.
