Sigma FP2 Ships November 11 at $2,199 With 6K Open Gate, No IBIS

Sigma will ship the FP2 on November 11 at $2,199 body-only, or $2,749 bundled with the new EVF-21 electronic viewfinder — and the company is pitching it, again, as the ultimate compact hybrid. Six years after the original fp claimed the title of world's smallest full-frame mirrorless, the FP2 keeps the same 24-megapixel-class resolution and the same brick-like body. What's changed is the sensor architecture, the screen, and a longer list of optional accessories you'll need to buy to get full functionality.

"The Sigma FP2 is a direct reflection of our unwavering commitment to optical excellence and our passion for meaningful engineering innovation," said Mark Amir-Hamzeh, President of Sigma Corporation of America. He added that Sigma "listened closely to the feedback from our creative community — vloggers, podcasters, photographers, and filmmakers alike."

Marketing language, yes. But the spec sheet deserves a hard look.

What's actually new inside?

The headline hardware change is a 24.5-megapixel partially stacked full-frame CMOS sensor. On paper it resembles the sensor in the Panasonic S5 II(X) and Nikon Z6 III — PetaPixel's Jordan Drake dismisses the older 24MP BSI chip as "that sensor," and Sigma has clearly moved on. Faster readout means less rolling shutter, which matters most for video work. Sigma has not confirmed whether it's the exact same silicon as its L-Mount partner's. It probably is.

The rear screen now tilts. That's a first for the line. The panel itself is unchanged — 3.15 inches, roughly 2.1 million dots — but tilt alone is a real usability gain for solo shooters. Tilting the screen also exposes vent fins that help with heat during long video takes. Sigma doesn't publish a runtime figure for those fins. Caveat emptor until independent tests appear.

Also gone: the Tone button. The top deck still carries only two command dials and no rear dial, so buyers accustomed to conventional handling should test before committing.

What does the modular design cost you?

The FP2 measures approximately 112.8 x 69.9 x 41.8 mm and weighs 460 grams with battery and SD card. The L-Mount dominates nearly the entire camera height. Sigma frames this as flexibility: "You can strip it down to a bare, pocketable-street-photography box adapted with vintage glass," the company says, "or build it up into a heavy-duty production rig with cine lenses, matte boxes, and wireless monitors."

But modularity here means absence. There's no hot shoe — that requires the optional HU-21 Hot Shoe Unit. There's no built-in viewfinder — the EVF-21, a 5.76-million-dot OLED with 0.88x magnification and 90° tilt, attaches via a side USB port and costs extra in the kit. And there's no in-body image stabilization, presumably because the compact chassis leaves no room. For working shooters on stabilized glass, fine. For handheld hybrid work, that's a gap competitors fill.

Physical I/O is generous for the size: two USB-C ports including one USB 3.2, full-size HDMI Type A, a timecode terminal that doubles as an external mic port, and 1/4-20 mounts on three sides including the bottom.

How does it perform for photo and video?

On the stills side, the FP2 runs Sigma's latest hybrid autofocus with AI-assisted subject tracking — human, dog, cat, bird, with Eye AF. Burst rate is 20 fps in JPEG and RAW (DNG), with a DNG buffer up to 180 frames at full speed. That buffer depth is competitive for the price class.

Native ISO spans 100 to 102,400 for stills and video, expandable down to ISO 6 for stills. Electronic shutter speeds run 30 seconds to 1/25,600, plus bulb up to five minutes. Note the flash sync ceiling: 1/50s without crop, and again, the hot shoe is an accessory.

Video is where Sigma aims the FP2. Highlights include 6K Open Gate recording up to 60p, native 4Kp60 at full width, 4Kp120 with a crop, log recording, and ProRes RAW HQ plus ProRes RAW up to 4Kp48 and 6Kp29.97. Paired with the HU-21, the camera supports 32-bit float audio. Sigma ships Color Modes including Rich, Warm Gold, Teal & Orange, and Sunset Red.

Internal storage sits at 70GB alongside a UHS-II SD slot. The new battery keeps the old form factor and promises about 30% longer life — rated at 370 shots or 130 minutes of recording. For a video-first body, 130 minutes is tight; plan on spares or a power brick via USB-C.

Bottom line

At $2,199 the FP2 undercuts several full-frame hybrids while offering 6K Open Gate and ProRes RAW in a 460-gram body. The trade-offs are real: no IBIS, no built-in EVF, no hot shoe, no mechanical shutter. Sigma is betting that a stripped-down core plus paid modules beats an all-in-one body — and November 11 is when working photographers can test whether that bet pays off on real shoots.
