Overview

The Sony a6400 pairs a 24.2MP APS-C Exmor CMOS sensor with the BIONZ X processor to deliver sharp, detailed images and smooth 4K video in a body that weighs just over 400 grams. Its headline feature is the 0.02-second autofocus system, which deploys 425 phase-detection and contrast-detection points across 84% of the sensor area. Real-time Eye AF locks onto human and animal eyes with remarkable tenacity, while Real-time Tracking uses Sony's AI-based algorithms to follow subjects through complex scenes. At 11 frames per second with the mechanical shutter or 8 fps in silent mode, the a6400 handles sports, wildlife, and fast-paced event shooting with confidence.

On the video side, the a6400 records 4K with full pixel readout and no pixel binning, producing clean, highly detailed footage. Support for S-Log2, S-Log3, and HLG gives colorists plenty of latitude in post-production, and 4:2:2 output over HDMI enables recording to external monitors or recorders at higher quality. The 180-degree tiltable touchscreen makes the camera a natural fit for vloggers and solo creators. This kit pairs the body with Sony's 18-135mm f/3.5-5.6 OSS lens, a practical all-in-one zoom for travel and everyday shooting, and rounds out the package with a travel case, spare battery, 32GB memory card, filters, tripod, and editing software so buyers can start shooting immediately.
