The Sony Alpha a6400 is a compact APS-C mirrorless camera that has become a go-to choice for content creators, vloggers, and enthusiast photographers who need serious autofocus performance and video capability in a travel-friendly body. Built around a 24.2MP APS-C Exmor CMOS sensor and Sony's BIONZ X processor, it produces clean, detailed images with natural color science that responds well to editing. The 425-point hybrid AF system — covering 84% of the frame — is the camera's standout feature, delivering the kind of sticky, reliable subject tracking and real-time Eye AF that transforms portrait and event shooting. Paired with the included 16-50mm f/3.5-5.6 power zoom lens (equivalent to 24-75mm), the kit gives you a versatile everyday focal range right out of the box.
In the hand, the a6400 feels solid despite its light weight. The magnesium alloy body has a comfortable grip and logically placed controls that become second nature after a few sessions. The 180-degree tilting touchscreen is genuinely useful for vlogging and low-angle compositions, and the menu system — while still Sony's older design — is navigable once customized. For video shooters, the combination of uncropped 4K recording, S-Log gamma profiles, and clean HDMI output makes it a capable B-camera or primary camera for documentary, YouTube, and short-form content. Where you feel the compromises are in the absence of IBIS — handheld video benefits enormously from a gimbal or stabilized lens — and in the modest battery life that demands spares for any extended outing. Within its price tier, the a6400 remains one of the most complete hybrid cameras available, especially once you invest in quality E-mount glass to unlock its sensor's full resolving power.
