Sony a7C vs Sony FX5
The bottom line
There's a real price gap here: the Sony a7C at $1,799 versus the Sony FX5 at $4,899. The extra buys you dual card slots and weather sealing. The question is whether those advantages are ones you'll use often enough to justify the premium — if not, the cheaper body is the smart buy.
Choose the Sony a7C if…
- ✓You shoot video seriously — it brings both mic and headphone jacks for monitored audio.
- ✓You want maximum detail for landscapes, studio or large prints — 24.2MP resolves noticeably more than 16.6MP and gives more cropping latitude.
- ✓You photograph moving subjects — it adds AF subject detection for animals that the other body lacks.
- ✓You're budget-conscious — it launched at $1,799, about $3,100 less, freeing money for lenses.
Choose the Sony FX5 if…
- ✓You shoot video seriously — it brings smoother 120p 4K vs 30p and no per-clip recording limit (vs a 29-min cap).
- ✓You need backup-while-you-shoot reliability — dual card slots (the other has one) matter for paid work like weddings and events.
- ✓You work outdoors — it's weather-sealed for rain and dust, the other isn't.
