Sigma BF vs Sigma fp
The bottom line
These two are closely matched. The differences below are where they diverge — weigh the ones that map to how you actually shoot, and let price and handling break the tie.
Choose the Sigma BF if…
- ✓You shoot in low light or indoors — a higher native ISO ceiling (102,400) gives it the edge after dark.
- ✓You work outdoors — it's weather-sealed for rain and dust, the other isn't.
Choose the Sigma fp if…
- ✓You shoot action, sports or wildlife — 18fps burst keeps up with fast, erratic movement where 8fps would drop frames.
Where they differ
- ›Price: the Sigma fp launched at $1,899, $100 under the Sigma BF — money that could go toward glass.
- ›Burst: the Sigma fp shoots 18fps to the Sigma BF's 8fps — the gap that decides whether you nail the peak moment in sports and wildlife.
- ›Durability: the Sigma BF is weather-sealed against dust and rain; the other isn't.
