Sigma Sigma fp Mirrorless Camera Review

The Sigma fp is a weird one. It's a full-frame mirrorless camera that looks and feels more like a minimalist box than a traditional camera, and it comes bundled with an MC-21 adapter for using Canon EF lenses. This setup is built for a very specific kind of creator who values modularity and a unique shooting experience over conventional features.

Performance is a mixed bag. The sensor lands in the 30th percentile, so image quality is fine but not class-leading. Its autofocus is similarly middle-of-the-road at the 45th percentile, and video specs are a weak spot at the 32nd. It has no in-body stabilization, which hurts handheld shooting. The bundled MC-21 adapter is a nice touch, letting you use a huge library of EF glass, but autofocus performance with adapted lenses can be hit or miss.

At over $2100, the value proposition is tough. You're paying a premium for a unique design and concept. For that money, you can get cameras from Sony, Canon, or Fujifilm that will outperform the fp in almost every measurable way, with better sensors, autofocus, and stabilization. This is a niche tool, not a general-purpose workhorse.

Stack it up against the competition and the gaps are clear. The Canon EOS R6 Mark II runs circles around it for autofocus and video. The Sony a7R IV offers a massive resolution advantage. Even Fujifilm's APS-C X-S20 delivers better all-around performance for much less money. The Sigma fp's main advantage is its modularity and the included lens adapter, but that's a trade-off most shooters won't want to make.

Buy this only if you're deeply into Sigma's unique design philosophy and you specifically need a modular, cinema-inspired camera body to adapt your existing Canon EF lenses. For everyone else—photographers, videographers, vloggers—there are simply better, more capable cameras at this price point that will be easier to live with.
