Sony a6400: Fast, Precise, and Versatile

The Sony a6400 is a compact APS-C mirrorless camera packed with features typically found in Sony’s full-frame models. It combines lightning-fast autofocus, 4K video, advanced tracking, and a robust build, making it a strong tool for photographers and content creators alike.

Blazing Fast Autofocus with AI-Powered Features

Sony equipped the a6400 with an advanced autofocus system that includes 425 phase-detection and 425 contrast-detection points. These cover around 84% of the image area, allowing the camera to lock focus in just 0.02 seconds.

The camera also features Real-time Eye AF and Real-time Tracking, both driven by AI. Eye AF tracks a subject’s eyes with incredible precision and can automatically detect and switch between the left and right eye. You can assign these settings to custom buttons for quick access. Real-time Tracking analyzes color, depth, and brightness to keep moving subjects sharply in focus—even when they briefly exit the frame.

Whether capturing athletes in action or animals in motion, the a6400 ensures tack-sharp focus with ease.

High-Speed Performance for Stills

Thanks to the BIONZ X image processor, the a6400 delivers high-speed continuous shooting at up to 11 fps with the mechanical shutter and 8 fps in silent mode, all with continuous autofocus and auto exposure. You can capture:

• Up to 116 JPEGs

• 46 RAW files

• 44 RAW+JPEGs in a single burst

This speed, combined with precise AF, makes it ideal for action, sports, or candid photography.

Improved Image Quality in All Conditions

The camera uses a 24.2MP APS-C Exmor CMOS sensor paired with Sony’s upgraded BIONZ X processor. This combination offers a native ISO range up to ISO 32,000 (expandable to 102,400 for stills), excellent dynamic range, and minimal noise—even in low light.

Inherited algorithms from Sony’s full-frame cameras further enhance detail retention, color accuracy, and overall image clarity.

Professional-Level 4K Video Recording

Video creators will appreciate the a6400’s internal UHD 4K recording. It captures footage with full pixel readout and no pixel binning, oversampling data at 2.4x to produce sharp, detailed 4K content.

Fast Hybrid AF ensures smooth focus transitions during video recording, even when the subject moves or an object crosses in front of the lens. You can also use touch focus during recording for quick adjustments.

Advanced Video Tools for Creators

The a6400 includes powerful video tools, such as:

• HLG (Hybrid Log-Gamma) for HDR workflows

• S-Log2 and S-Log3 for color grading flexibility

• Full HD 120 fps for slow-motion editing

• Zebra function and Gamma Display Assist

• Proxy recording for easier editing

• Interval recording for time-lapse videos (1 to 60 seconds, up to 9999 frames)

These features make the a6400 a serious contender for vloggers and filmmakers.

Designed for Versatility and Durability

The a6400 has a robust magnesium-alloy body with weather sealing around the dials and buttons, offering protection from dust and moisture. Sony also included an anti-dust system for the optical filter to minimize sensor contamination.

Despite its durability, the camera remains compact and lightweight—ideal for travel and handheld shooting.

Flexible Touchscreen and Viewfinder

Framing and monitoring are simple with the 3.0″ tilting touchscreen LCD. It flips 180° upward and 74° downward, making it perfect for vlogging, selfies, or low/high-angle shots. The touchscreen also supports:

• Touch Focus

• Touch Shutter

• Touch Tracking for Real-time Tracking activation

In addition, the 2.36m-dot XGA Tru-Finder OLED EVF offers a bright and clear view with a smooth 120 fps refresh rate, which helps track fast-moving subjects with ease.

Customization and Connectivity

Photographers can tailor the camera to their workflow with:

• 89 customizable functions

• 8 assignable buttons

• My Dial and My Menu options

• Image rating system

• Menu help screens

For sharing or remote shooting, the a6400 supports Wi-Fi, NFC, and Bluetooth. It also works seamlessly with Sony’s Imaging Edge Mobile app, allowing easy file transfer and remote control from a smartphone or tablet.

Final Thoughts

The Sony a6400 brings pro-level features to a compact, mirrorless body. Its powerful autofocus, fast burst shooting, professional-grade video tools, and robust build quality make it ideal for photographers, vloggers, and filmmakers who demand flexibility without compromise.
