Sony a6300 → Sony a6400
Is the upgrade worth it? Every change on the spec sheet, and an honest read on who should bother.
The bottom line
The Sony a6400 is the direct successor to your Sony a6300, released 3 years later. Across the full spec sheet it improves 8 items and steps back on 1. The changes that matter most: 10-bit internal recording is added. The Sony a6400 lists at $899 (the Sony a6300 launched at $1,099, and older bodies typically sell for well under launch price on the used market). If several of the gains below map to how you shoot, this is a substantial step up; if none do, your current body keeps doing everything it does today.
Upgrade to the Sony a6400 if…
- ✓You shoot video seriously — it brings 10-bit internal colour.
- ✓You shoot in low light or indoors — AF that focuses down to -3 EV gives it the edge after dark.
Stick with the Sony a6300 if…
- •You work outdoors — it's weather-sealed for rain and dust, the other isn't.
- •None of the headline changes map to what you actually shoot — the camera you own doesn't get worse when a successor launches.
