Is the upgrade worth it? Every change on the spec sheet, and an honest read on who should bother.
The bottom line
The Sony a7R VI is 2 generations newer to your Sony a7R IV, released 6 years later. Across the full spec sheet it improves 7 items and steps back on 4. The changes that matter most: 8K video arrives; subject-detection AF is added. The Sony a7R VI lists at $4,499 (the Sony a7R IV launched at $3,499, and older bodies typically sell for well under launch price on the used market).

Upgrade to the Sony a7R VI if…
- ✓You shoot video seriously — it brings 8K capture (up to 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 shoot in low light or indoors — AF that focuses down to -4 EV gives it the edge after dark.
Stick with the Sony a7R IV if…
- •You're budget-conscious — it launched at $3,499, about $1,000 less, freeing money for lenses.
- •None of the headline changes map to what you actually shoot — the camera you own doesn't get worse when a successor launches.
