Overview

The Sony Alpha a6400 is a compact APS-C mirrorless camera built around speed and precision. At its core is a 24.2-megapixel Exmor CMOS sensor paired with the BIONZ X image processor, delivering detailed stills with accurate color reproduction. The standout feature is its autofocus system — 425 phase-detection and 425 contrast-detection points blanket 84% of the sensor, achieving lock-on in as little as 0.02 seconds. Real-time Eye AF works for both humans and animals, while Real-time Tracking uses Sony's AI-based subject recognition to follow moving targets with remarkable consistency. Combined with 11fps continuous shooting with full AF/AE tracking, the a6400 is built for fast-moving subjects.

On the video side, the a6400 records oversampled 4K footage with full pixel readout and no pixel binning, producing sharp, detailed video. Built-in time-lapse and slow/quick motion modes let you create dynamic content without post-processing. The 180-degree tiltable touchscreen LCD makes it a natural fit for vloggers and solo creators, while the customizable controls and clean HDMI output cater to more advanced production workflows. This kit pairs the body with Sony's 18-135mm f/3.5-5.6 OSS lens, an optically stabilized zoom that covers a versatile focal range from wide-angle scenes to telephoto reach — making it a practical one-lens solution for travel, events, and everyday shooting.
