Verdict

The Sony A6400 is a versatile APS-C mirrorless camera featuring a 24.2MP Exmor CMOS sensor and a BIONZ X processor that enables high-resolution 4K video recording at 30fps and 1080p high-speed capture at 120fps. Its standout characteristics include a world-class hybrid autofocus system with 425 phase-detection points, real-time eye tracking, and a lightning-fast 0.02-second focus acquisition speed. Key pros include a robust magnesium-alloy body with weather-sealing, an 11fps continuous shooting rate, and a 180-degree flip touchscreen ideal for vlogging. However, it lacks in-body image stabilization (IBIS) and a headphone jack, suffers from noticeable rolling shutter in 4K, and has a complex menu system that can be unintuitive for new users.
