Key features

24.2MP APS-C Exmor CMOS sensor: Delivers detailed stills with good dynamic range, giving room to recover shadows and highlights.
425 phase-detection autofocus points: Real-time Eye AF and Real-time Tracking follow people and animals across the frame.
Continuous shooting up to 11 frames per second: Autofocus and exposure tracking continue during the burst, which helps with moving subjects.
Internal 4K video with microphone input: You can record 4K to the card and plug in an external microphone for better audio.
3.0-inch touchscreen that tilts up 180 degrees: The screen faces forward for self-recording.

What we like

Autofocus that is fast and dependable for children, pets and amateur sport.
One of the broadest lens ecosystems available for APS-C.
A compact body that travels well.
A microphone input and forward-facing screen for vlogging.
Fast burst shooting with tracking.

What to consider

There is no in-body image stabilisation, so handheld video and slow shutter speeds rely on stabilised lenses.
The battery is Sony’s smaller older type, so a spare is wise.
There is no headphone socket, and the flip-up screen can be blocked by a microphone mounted on top.
The menu system is less friendly than on newer Sony bodies.

Who should buy it

The Sony Alpha a6400 Mirrorless Camera is a good match if autofocus reliability is your priority. That covers parents photographing children, pet owners, amateur sports shooters and people recording video of themselves talking to camera. Its lens ecosystem matters as your needs grow, because you can add lenses from Sony and third parties.

Look elsewhere if you shoot a lot of handheld video and want stabilisation built into the body, or if you need to monitor audio through headphones. Complete beginners who want the simplest menus may also prefer a newer design.

How it compares

The Sony Alpha a6400 sits in the mid-range of APS-C mirrorless cameras. Entry-level models below it are often cheaper and simpler but tend to have less capable autofocus tracking and slower burst rates. Models above it add in-body stabilisation, larger batteries, headphone sockets and updated menus. Because the a6400 is an older design, newer alternatives in Sony’s own range may add features you want. Its strengths remain autofocus and lens choice, which are the things that are hardest to work around.

What to check before you buy

Whether the listing is body only or includes a lens. Common kits pair it with a 16-50mm or an 18-135mm zoom, and the difference in versatility is significant.
Whether bundled accessories are from Sony or third parties.
Whether a memory card is included. Usually it is not, and a fast SD card is recommended for 4K.
Whether a newer Sony model adds features you need.
The exact configuration, confirmed with the retailer.

Frequently asked questions

Is the Sony a6400 good for vlogging?

It has internal 4K, a microphone input and a screen that tilts up 180 degrees. The limits are no in-body stabilisation, no headphone socket, and a screen that a top-mounted microphone can block.

Does the Sony a6400 have image stabilisation?

Not in the body. Stabilisation depends on using lenses that have it built in.

Is the Sony a6400 good for beginners?

It can be. The autofocus does much of the work, and the body is small. The menu system is less friendly than on newer Sony cameras, so expect a learning period.
