Sony a6600 → Sony a6700
Is the upgrade worth it? Every change on the spec sheet, and an honest read on who should bother.
The bottom line
The Sony a6700 is the direct successor to your Sony a6600, released 4 years later. Across the full spec sheet it improves 9 items and steps back on 2. The changes that matter most: 4K goes from 30p to 120p; subject-detection AF is added. The Sony a6700 lists at $1,399 (the Sony a6600 launched at $1,399, 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 a6700 if…
- ✓You shoot video seriously — it brings smoother 120p 4K vs 30p and no per-clip recording limit (vs a 29-min cap).
- ✓You photograph moving subjects — it adds AF subject detection for animals and vehicles that the other body lacks.
- ✓You vlog or shoot handheld solo — the fully-articulating screen flips to face you and there's a mic input for clean audio.
- ✓You shoot in low light or indoors — AF that focuses down to -3 EV gives it the edge after dark.
Stick with the Sony a6600 if…
- •None of the headline changes map to what you actually shoot — the camera you own doesn't get worse when a successor launches.
