The Sony A6400 is a mid-range APS-C mirrorless camera that has remained popular since its release in 2019. It strikes a balance between performance, portability, and price, making it a solid choice for enthusiasts, travel photographers, and content creators. While it doesn’t have the latest features of Sony’s newer models, its autofocus system, 4K video capabilities, and compact design still hold up well in 2025.
Key Features and Highlights
1. Outstanding Autofocus Performance
The A6400 boasts a 425-point phase-detection autofocus (AF) system with real-time tracking and Eye AF for both humans and animals (after a firmware update). Its 0.02-second AF speed is impressive, making it reliable for fast-moving subjects like sports or pets48.
2. 4K Video with No Crop
Unlike some competitors, the A6400 records 4K video using full pixel readout without a crop, resulting in sharper footage. It also supports S-Log2 and S-Log3 for better dynamic range in post-production, though it lacks 10-bit recording17.
3. Compact and Travel-Friendly
Weighing just 403g (body only), the A6400 is easy to carry for travel or vlogging. Its 180° flip-up touchscreen is useful for self-recording, though it can be obstructed by an external microphone7.
4. Strong Lens Ecosystem
Sony’s E-mount system offers a wide selection of lenses, from affordable Sigma primes to high-end G Master glass. The 16-50mm kit lens is compact but not the sharpest, so many users opt for third-party alternatives like Sigma’s 16mm f/1.4 for better low-light performance16.
Pros and Cons
Pros:
✔ Fast and reliable autofocus – Excellent for tracking moving subjects.
✔ Uncropped 4K video – Better than many competitors in its class.
✔ Compact and lightweight – Great for travel and everyday use.
✔ Good battery life – Around 410 shots per charge (CIPA rating).
✔ Wide lens selection – Compatible with both APS-C and full-frame E-mount lenses.
Cons:
✖ No in-body stabilization (IBIS) – Video handheld footage can be shaky without a stabilized lens or gimbal.
✖ Limited touchscreen functionality – Only for focus selection, not menu navigation.
✖ Mediocre kit lens – The 16-50mm lens is convenient but not the sharpest.
✖ No headphone jack – Makes audio monitoring difficult for videographers.
Who Is This Camera For?
1. Travel and Street Photographers
Its compact size and strong autofocus make the A6400 a great companion for travel. Pair it with a prime lens like the Sigma 30mm f/1.4 for low-light flexibility.
2. Content Creators and Vloggers
The 4K video quality and flip-up screen are useful for vlogging, though the lack of stabilization means a gimbal may be necessary for smooth footage.
3. Enthusiasts Upgrading from Smartphones
If you want better image quality than a phone but aren’t ready for a full-frame camera, the A6400 is a good middle ground.
Buying Recommendations
Consider the body-only option if you plan to buy better lenses separately.
For vlogging, add a compact stabilized lens like the Sony 10-18mm f/4 or a small gimbal.
Battery life is decent, but carrying a spare (NP-FW50) is advisable for longer shoots.

Final Thoughts
The Sony A6400 remains a strong choice in 2025 for those who prioritize autofocus speed, 4K video, and portability. While it lacks some modern features like in-body stabilization and a fully articulating screen, its performance and lens compatibility make it a versatile option for photographers and videographers on a budget. If you can find it at a good price, it’s still worth considering—especially if you’re stepping up from a smartphone or an older DSLR.
