Overview

The Sony Alpha a6400 (ILCE6400L/B) is a compact APS-C mirrorless camera that punches well above its size class. At its core is a 24.2-megapixel APS-C Exmor CMOS sensor paired with Sony's BIONZ X image processor, delivering sharp, detailed images with an ISO range of 100–32000 (expandable to 102400). The real standout feature is its autofocus system: 425 phase-detection and 425 contrast-detection points blanket 84% of the sensor area, and Sony's Real-Time Eye AF tracks human and animal eyes with remarkable reliability. Acquisition speed is rated at just 0.02 seconds, making it one of the fastest-focusing cameras available. Continuous shooting at up to 11fps with full AF/AE tracking means the a6400 handles fast action, wildlife, and street photography with confidence.

For video shooters, the a6400 records oversampled 4K (3840x2160) at 30fps with no recording time limit — a critical advantage for event videographers, interviewers, and long-form content creators. The 180-degree flip-up touchscreen LCD makes it a natural choice for vlogging and self-recording, and the camera supports S-Log2, S-Log3, and HLG profiles for flexible color grading in post-production. Bundled with the compact E PZ 16-50mm f/3.5-5.6 OSS kit lens, the package offers a versatile 24-75mm equivalent zoom range in a body that weighs just 403 grams. Wi-Fi and Bluetooth connectivity enable easy image transfer and remote control via Sony's Imaging Edge mobile app, rounding out a feature set that makes the a6400 one of the most capable and popular APS-C cameras on the market.
