Sony a7 V vs Sony FX3
The bottom line
Same line, different generation: the Sony a7 V (2025) moves ahead on burst speed (30fps vs 10fps), resolution (33MP vs 12.1MP) and subject-detection AF. If those newer features aren't ones you'll actually use, the Sony FX3 gives you most of the experience for less.
Choose the Sony a7 V if…
- ✓You shoot action, sports or wildlife — 30fps burst plus dedicated subject-tracking AF keeps up with fast, erratic movement where 10fps would drop frames.
- ✓You want maximum detail for landscapes, studio or large prints — 33MP resolves noticeably more than 12.1MP and gives more cropping latitude.
- ✓You're budget-conscious — it launched at $2,898, about $1,001 less, freeing money for lenses.
Choose the Sony FX3 if…
- ✓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 — a higher native ISO ceiling (102,400) and AF that focuses down to -6 EV give it the edge after dark.
