Sony A6400 Review: The Autofocus Bargain That Endures
The Sony A6400 remains one of the best value APS-C cameras thanks to autofocus that still holds up years after launch, a flip-up screen good for vlogging and clean 4K video. Its main compromises are the lack of in-body stabilisation and a cramped menu system. If you want stabilisation and a newer sensor, step up to the Sony A6700; if you prefer dials and colour science, look at the Fujifilm X-T30 II.
The Sony A6400 is still one of the smartest value buys in APS-C, delivering fast real-time eye autofocus, a selfie-friendly flip-up screen and clean 4K in a compact body, which keeps it relevant well beyond its launch.
Autofocus is the A6400’s calling card, and it was so far ahead at release that it still competes with newer rivals. What the years have exposed are its gaps, chiefly the missing in-body stabilisation and an aging interface, so the question is whether those omissions matter for how you shoot or whether the low price makes it a bargain worth grabbing.
The top picks, ranked
Sony A6400
The Sony A6400 is aimed at enthusiasts, content creators and upgraders from a phone who want fast, reliable autofocus without spending a lot. Its standout strengths are real-time eye and tracking autofocus that still shames many newer cameras, a flip-up screen suited to vlogging and clean oversampled 4K video. The real weaknesses are the absence of in-body stabilisation, so handheld video needs a stabilised lens or gimbal, plus a dated menu and modest battery. For buyers who prize autofocus and value over stabilisation, it is still an easy recommendation.
Pros
- Fast, reliable real-time autofocus
- Flip-up screen good for vlogging
- Excellent value
Cons
- No in-body stabilisation
- Dated menus and modest battery
Fujifilm X-T30 II
The X-T30 II is the A6400’s most direct rival for enthusiasts who want tactile control and Fujifilm’s film simulations. It offers a 26MP sensor, dedicated dials and a deeper native lens range, cross-shopping closely with the Sony. Against the A6400 it gives up some autofocus stickiness for faster subjects but wins on handling and out-of-camera colour, and it also lacks in-body stabilisation.
Pros
- Dedicated dials and film simulations
- Deep native lens lineup
- Higher-resolution sensor
Cons
- Autofocus less sticky for fast action
- No in-body stabilisation
Canon EOS R10
The EOS R10 is a newer APS-C body that cross-shops with the A6400 for buyers who want fast bursts and Canon’s excellent Dual Pixel autofocus. It offers a deeper grip and quicker continuous shooting, though Canon’s native APS-C lens range is still thin. Like the Sony it has no in-body stabilisation, but its subject detection is a generation newer.
Pros
- Fast burst shooting
- Modern subject-detection autofocus
- Comfortable grip
Cons
- Limited native APS-C lenses
- No in-body stabilisation
Sony ZV-E10 II
The ZV-E10 II shares Sony’s E-mount and adds a newer 26MP sensor, a fully articulating screen and creator tools the A6400 lacks. It cross-shops for buyers who care more about video and vlogging than a viewfinder, which it omits. Compared with the A6400 it gains a better sensor and articulating screen but still has no in-body stabilisation, relying on an electronic mode instead.
Pros
- Newer sensor and better video
- Fully articulating screen
- Creator-focused features
Cons
- No viewfinder
- No in-body stabilisation
Nikon Z50 II
The Z50 II is a comfortable, modern APS-C body with improved subject-detection autofocus inherited from Nikon’s flagship line and a fully articulating screen. It cross-shops with the A6400 for buyers who value grip and simplicity over the smallest size. Against the Sony it offers newer autofocus and better ergonomics but shares the lack of in-body stabilisation and a smaller native lens range.
Pros
- Comfortable grip and controls
- Modern subject-detection autofocus
- Articulating screen
Cons
- No in-body stabilisation
- Smaller native lens range
Sony A6600
The A6600 sits above the A6400 in Sony’s older lineup, adding in-body stabilisation and a larger battery while keeping the same 24MP sensor. It is a natural upgrade cross-shop for A6400 buyers who want stabilisation without moving to the pricier A6700. The trade-off is that its sensor and autofocus are the same generation as the A6400, so the main gains are stabilisation and endurance.
Pros
- In-body stabilisation over the A6400
- Large battery for long days
- Same proven autofocus
Cons
- Same-generation sensor as the A6400
- Older menu system
Fujifilm X-S20
The X-S20 offers a big step up in video and stabilisation over the A6400 in a grip-forward body with excellent battery life. It cross-shops for buyers willing to spend more for in-body stabilisation and stronger video while keeping an APS-C size. Compared with the A6400 it is a clear generation ahead on features, at a higher price, with access to Fujifilm’s deeper lens range.
Pros
- In-body stabilisation and strong video
- Excellent battery life
- Access to Fujifilm lenses
Cons
- Costs noticeably more
- Single card slot
What to look for
Who should buy the Sony A6400 The A6400 suits budget-conscious enthusiasts, first-time interchangeable-lens buyers and creators who prize autofocus over stabilisation. It is a great fit for family, travel and street photography, and for vloggers who use a stabilised lens or gimbal. It is a weaker choice if you shoot a lot of handheld video without stabilisation gear, where a camera with in-body stabilisation like the A6600 or Fujifilm X-S20 serves you better.
Key features that matter The A6400’s headline feature is real-time autofocus with eye detection for people and animals, which locks on quickly and holds. Its 24MP sensor delivers clean, detailed files, and it records oversampled 4K that still looks sharp. The 180-degree flip-up screen supports selfies and vlogging, though it can be blocked by a hotshoe microphone. These strengths explain why the camera has stayed popular for years.
How it compares to rivals Against the Fujifilm X-T30 II, the A6400 trades dials and colour science for stickier autofocus. Against the Canon EOS R10 and Nikon Z50 II it gives up newer subject detection and better grips but stays smaller and often cheaper. Within Sony’s own range, the A6600 adds stabilisation and battery life, while the ZV-E10 II modernises the sensor for video-first creators who skip the viewfinder.
Verdict on value and lenses The A6400’s value case rests on its low price and the breadth of the E-mount system. It accepts both APS-C and full-frame E-mount lenses, so it can grow with you, though the smaller native APS-C range means many owners add full-frame glass. If autofocus and price top your list and you can live without in-body stabilisation, it is still one of the best-value cameras you can buy.

Frequently asked questions
Is the Sony A6400 still worth buying?
Yes, for buyers who prioritise autofocus and value. Its real-time eye and tracking autofocus still competes with much newer cameras, and it shoots clean 4K in a compact body at a low price. The main reasons to spend more are in-body stabilisation and a newer sensor, which the A6700 provides.
Does the Sony A6400 have in-body stabilisation?
No. The A6400 has no in-body image stabilisation, so it relies on optically stabilised lenses or a gimbal for smooth handheld video. If stabilisation matters to you, the Sony A6600, A6700 or Fujifilm X-S20 all include it.
Is the Sony A6400 good for vlogging?
It is capable, thanks to a 180-degree flip-up screen and excellent face and eye autofocus. The catch is that a hotshoe microphone can block the flip-up screen, and there is no in-body stabilisation. Creators who want a fully articulating screen and stabilisation may prefer the Sony ZV-E10 II.
How does the A6400 compare to the A6600?
They share the same 24MP sensor and autofocus generation, so image quality is similar. The A6600 adds 5-axis in-body stabilisation and a larger battery, making it a better handheld video and all-day camera, while the A6400 costs less and stays a strong value pick.
How does the A6400 compare to the Fujifilm X-T30 II?
The X-T30 II offers dedicated dials, film simulation colour and a slightly higher-resolution 26MP sensor, while the A6400 counters with stickier real-time autofocus. Both lack in-body stabilisation, so the choice often comes down to whether you prefer Sony’s autofocus or Fujifilm’s handling and colour.
Does the Sony A6400 shoot 4K video?
Yes. It records oversampled 4K at up to 30p, which stays sharp and detailed, plus Full HD at higher frame rates for slow motion. Video is 8-bit and there is no in-body stabilisation, so it is best paired with a stabilised lens for handheld work.
What lenses fit the Sony A6400?
It uses the Sony E-mount and accepts both APS-C E-mount lenses and full-frame E-mount lenses. The native APS-C range is smaller than Fujifilm’s, so many owners add compact full-frame lenses to fill gaps, which expands options at the cost of some size and price.
Is the A6400 good for beginners?
Yes. Its autofocus does much of the hard work, it is compact and easy to carry, and it grows with you through the E-mount lens system. The dated menus take some learning, but the low price and reliable results make it a solid first interchangeable-lens camera.
The bottom line
The Sony A6400 endures as one of the best value APS-C cameras, with autofocus that still outclasses many newer rivals, a vlog-friendly flip-up screen and clean 4K, held back mainly by the missing in-body stabilisation and dated menus. If you want stabilisation and a newer sensor, step up to the Sony A6700, or choose the Fujifilm X-T30 II if you prefer dials and film-simulation colour.
