Sony's best-selling APS-C mirrorless with exceptional autofocus and no-blackout burst.
The Sony A6400 was launched in 2019 and became one of Sony's most popular cameras. With a 24.2MP APS-C sensor, the world's fastest autofocus at its launch with 0.02-second AF acquisition, and Real-time Eye AF for both humans and animals, it targeted vloggers, enthusiasts, and hybrid shooters.
Key features include 425-point phase-detect AF covering 84 percent of the sensor, Real-time Tracking AF, 11fps with AF tracking, 4K video without recording limit, and a 180-degree tilt screen for selfie shooting. The body is compact and weather-sealed. Battery life is around 360 shots.
The A6400 is praised for outstanding autofocus that punches well above its price class, reliable 4K video, and the no-blackout electronic viewfinder shooting. It is criticised for the lack of IBIS which the A6600 adds at a premium, and the tilt screen that only flips up not to the side.
Excellent value used. Check the tilt screen mechanism, AF tracking performance, and battery condition. The A6400 versus A6600 decision comes down to whether IBIS and a larger battery are worth the premium. For many shooters the A6400 is the sweet spot.
