Leica SL3-P vs Sigma fp L
The bottom line
There's a real price gap here: the Sigma fp L at $2,499 versus the Leica SL3-P at $6,690. The extra buys you faster 40fps burst, 8K video and in-body stabilisation. 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 Leica SL3-P if…
- ✓You shoot action, sports or wildlife — 40fps burst plus dedicated subject-tracking AF keeps up with fast, erratic movement where 10fps would drop frames.
- ✓You shoot video seriously — it brings 8K capture (up to 30p) and both mic and headphone jacks for monitored audio.
- ✓You shoot handheld — in-body stabilisation lets you use slower shutter speeds and steadies video, which the other body can't do without a stabilised lens.
- ✓You shoot in low light or indoors — a higher native ISO ceiling (200,000) gives it the edge after dark.
Choose the Sigma fp L if…
- ✓You want maximum detail for landscapes, studio or large prints — 61MP resolves noticeably more than 44MP and gives more cropping latitude.
- ✓You're budget-conscious — it launched at $2,499, about $4,191 less, freeing money for lenses.
- ✓You value portability — at 427g (15.1 oz) it's noticeably lighter than the 768g (1.69 lb) alternative for travel and all-day carry.
