The Sony A6400 and the A6000 share a compact APS-C design and the same E-mount, but the A6400 is a later camera with a more modern focus system, a touchscreen and 4K video. Choose the A6400 if you shoot moving subjects or video, and the A6000 if you want a simple, light camera for general use.
What Each Camera Is For
The A6000 is an older model that introduced many people to mirrorless photography. It remains useful for travel, family events and learning exposure. The A6400 sits further up the same line and targets people who want better tracking for people and animals, plus video features such as 4K recording and a screen that flips up for vlogging.
Key Differences

| Video | 4K class | Full HD class |
| Eye detection | Includes subject-based eye tools | More limited |
| Typical position | Later, more capable | Earlier, simpler |

What the Differences Mean in Use
Autofocus is the main practical change. When you photograph children running, pets or sports, a newer tracking system holds focus on the subject more reliably than an older one, so more frames are usable. If you mostly photograph landscapes, buildings or posed portraits, the difference is smaller.
The flip-up touchscreen helps with low or high angles and with framing yourself. Touch focus also speeds up video work. Both cameras use the same lenses, so you can move lenses between them without any cost.
How to Choose
- List what you shoot. Action and video favor the A6400.
- Decide if a flip-up, touch-enabled screen would help your style.
- Look at what a used example of each costs on the day and what lens you could add with the difference.
- Consider battery life and card needs, which you should confirm on the maker’s page.
Who Should Choose Which
- Choose the A6400 for sports, wildlife, pets, children and casual video.
- Choose the A6000 for learning, travel and cases where a light, simple body is enough.
- Choose a better lens before a better body if your photos feel soft or flat.
Remember that accessories, spare batteries and cases add to the real cost of any change, so count those too, and read the maker’s documents for battery, card and port details before you commit to a purchase.
