Leica SL3-P vs Sigma fp

The bottom line

There's a real price gap here: the Sigma fp at $1,899 versus the Leica SL3-P at $6,690. The extra buys you faster 40fps burst, 8K video and 44MP of resolution. 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 18fps would drop frames.
  • ✓You shoot video seriously — it brings 8K capture (up to 30p) and both mic and headphone jacks for monitored audio.
  • ✓You want maximum detail for landscapes, studio or large prints — 44MP resolves noticeably more than 24.6MP and gives more cropping latitude.
  • ✓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.

Choose the Sigma fp if…

  • ✓You're budget-conscious — it launched at $1,899, about $4,791 less, freeing money for lenses.
  • ✓You value portability — at 422g (14.9 oz) it's noticeably lighter than the 768g (1.69 lb) alternative for travel and all-day carry.

  • ›Resolution: 44MP on the Leica SL3-P vs 24.6MP — more detail and crop room, at the cost of larger files.
