Sigma Sigma fp Mirrorless Full-Frame Digital Camera with Review
The Sigma fp offers great video in a tiny body, but its missing features and average autofocus make it a hard sell for most people.
Overview
The Sigma fp is a weird one, and that's kind of the point. It's a full-frame mirrorless camera that's built like a tiny, minimalist brick. The 24.6MP BSI sensor lands in the 62nd percentile, which means you're getting solid, detailed image quality that's a step above average. But the real story here is its focus on being a modular tool, especially for video, where it scores in the 69th percentile.
That modularity comes with trade-offs, though. There's no built-in stabilization (40th percentile), no viewfinder unless you add one, and the autofocus system sits in the 44th percentile. It's not a camera you just pick up and shoot. It's a camera you build around a specific need, and for $2419, you're paying for that unique, stripped-down approach.
Performance
Performance is a mixed bag, heavily dependent on what you're doing. For video, it's a capable little box, hitting that 69th percentile. It shoots 4K, and the full-frame sensor gives you that cinematic look and good low-light performance. But the lack of stabilization means you'll need a gimbal or a very steady hand for anything but tripod work.
For stills, it's more middle-of-the-road. The sensor is good, but the autofocus at the 44th percentile is a clear weak spot compared to modern competitors. Don't expect to track fast action. The burst rate is down at the 38th percentile, so it's not a sports camera either. It's a deliberate shooter's tool.

Value & Pricing
At $2419 for the body, the Sigma fp is a niche value proposition. You're not paying for a complete, polished camera experience. You're paying for a unique, modular core. If you're a filmmaker who wants to build a compact cinema rig, or a stills photographer who values ultimate simplicity and doesn't need fast AF, that price might make sense. For everyone else, that money buys you a much more complete and capable all-rounder from Sony, Canon, or Fujifilm.
vs Competition
Compared directly, the Sigma fp makes sacrifices others don't. The Sony a7R IV, for example, smokes it in resolution and has far superior autofocus. The Fujifilm X-S20, while APS-C, offers incredible stabilization, much better autofocus, and a more versatile feature set for hundreds less. Even the Canon EOS R7, an APS-C camera, has blazing fast burst shooting and pro-level AF that the fp can't touch. The fp's only real advantage is its ultra-compact full-frame form factor and modularity. You choose it despite its weaknesses, not because it beats others on paper.

Verdict
The Sigma fp is a fascinating specialist, not a generalist. I can only recommend it if you specifically want the smallest possible full-frame base for a custom video rig, or if you're a stills photographer who actively dislikes the complexity of modern cameras. Its 69th percentile video score is good, but its 44th percentile autofocus and lack of stabilization are real handicaps. For 99% of shooters, a more conventional camera from Sony, Fujifilm, or Canon will be faster, easier, and more versatile for the same money or less.
