Sony a7 III vs Sony a7R VI
The bottom line
Same line, different generation: the Sony a7R VI (2025) moves ahead on resolution (60.1MP vs 24.2MP), 8K video and subject-detection AF. The Sony a7 III is still the value pick at $1,999 ($4,499 for the Sony a7R VI). If those newer features aren't ones you'll actually use, the Sony a7 III gives you most of the experience for less.

- ✓You shoot video seriously — it brings 8K capture (up to 30p) and no per-clip recording limit (vs a 29-min cap).
