**Short answer: Sigma announced the FP2 on October 23, 2026, billing it as the world's smallest full-frame mirrorless camera. It packs a 24.5MP partially stacked sensor, 6K video, and a tilting screen into a 460-gram box for $2,199 body-only, shipping November 11.** I have shot with a Leica M11 and a 50mm for years, so here is what this camera actually means for working photographers, beyond the launch-day spec sheet.
## What the Sigma FP2 is
Sigma announced the FP2 on October 23, 2026, as the second generation of its fp series. The original Sigma fp launched in 2019 with a radical idea: strip the camera down to a plain modular box, smaller than anything else with a full-frame sensor, and let the shooter build it up with accessories. The FP2 keeps that philosophy and fixes the original's weaknesses.
The headline changes: a new 24.5MP partially stacked full-frame sensor, a tilting rear screen (the original's fixed screen was its most criticized feature), 70GB of built-in memory, a larger battery, and continuous shooting up to 20 frames per second. Remarkably, Sigma fit all of it into a body even smaller than the original, measuring just 112.8 x 69.9 x 41.8mm and weighing 460 grams with battery and memory card.
Sigma is explicit about the positioning: this is a hybrid camera for stills and video, aimed at creators who want full-frame image quality in the smallest possible package. It uses the L-mount, which means it shares lenses with Leica, Panasonic, and Sigma's own glass. That last detail matters more than it might seem, and I will come back to it.
## The full spec sheet, translated
Launch announcements bury the useful numbers in marketing language. Here are the verified specifications, with what each one actually means in practice:
- **Sensor:** 24.5 megapixel partially stacked full-frame CMOS, 35.9 x 23.9mm, outputting 6016 x 4012 pixel files. Partially stacked means faster readout than a conventional sensor, which is what enables the 20fps shooting and the improved autofocus. For context, 24.5MP is the current sweet spot: enough for large prints and client delivery, without the storage punishment of 60MP files.
- **ISO range:** 100 to 102,400, expandable down to ISO 6, 12, 25, and 50. The expanded low ISOs are a video-shooter feature, letting you hold wide apertures in bright light without ND filters.
- **Continuous shooting:** up to 20fps, with 8, 5, and 3fps options. 49 autofocus points with improved subject tracking, per Sigma.
- **Video:** 6K open-gate at 60fps, 4K at 60fps uncropped, 4K at 120fps with a 1.5x crop, and Full HD at 120fps. Dynamic range rated at 14+ stops. Open-gate means the sensor records its full area, so you can reframe vertical crops from horizontal footage later, a genuinely useful feature for anyone delivering both stills-style verticals and horizontal video.
- **Screen:** 2.1-million-dot, 3.15-inch tilting LCD touchscreen. Tilts for waist-level and overhead shooting. This single change answers the biggest complaint about the original fp.
- **Storage:** 70GB of internal memory plus a UHS-II SD card slot, with USB-C SSD recording as a third option. The internal memory is unusual and practical: you can shoot without a card in an emergency.
- **Battery:** the new BP-91, which is identical to the Panasonic BLK-22 used across Lumix cameras. Rated at 370 shots or 130 minutes of video. Sharing a battery standard with Panasonic is a quiet pro move: spares are cheap and available everywhere.
- **Shutter:** 30 seconds to 1/25,600th. Evaluative and spot metering, exposure compensation to plus or minus 5EV.
- **Connectivity:** two USB-C ports, full-size HDMI output, 3.5mm stereo mic input.
- **Viewfinder:** none built in, which is how it stays so small. The optional EVF-21 electronic viewfinder offers a 5.76-million-dot panel with 0.88x magnification. There is also an LVF-21 LCD viewfinder that turns the rear screen into a large loupe-style finder, at the cost of much of the size advantage.
- **Accessories:** HG-11 handgrip, HU-21 hot-shoe unit (which shares its protocol with Panasonic and OM System, so existing flashes may work), and the viewfinders above.
## FP2 vs the original fp: every upgrade in one place
**Quotable summary: the FP2 keeps the original fp's box-shaped modular concept and upgrades nearly everything inside it, adding a tilting screen, a faster 24.5MP stacked sensor, 70GB of internal memory, and a bigger battery, all in a body smaller than the 2019 original.**
I compiled this from the launch coverage so you can see the generational jump at a glance:
- **Sensor:** original fp used a conventional 24.6MP full-frame sensor; the FP2 moves to a 24.5MP partially stacked sensor with faster readout, better autofocus, and subject tracking.
- **Rear screen:** fixed on the original, a constant source of complaints; tilting touchscreen on the FP2.
- **Continuous shooting:** the original topped out well below the FP2's 20fps.
- **Video:** the original fp shot 4K; the FP2 adds 6K 60p open-gate, 4K 120p, and 14+ stops of dynamic range.
- **Internal memory:** none on the original; 70GB on the FP2.
- **Battery:** the original's BP-51 was widely considered undersized; the FP2's BP-91 is larger and shared with Panasonic's BLK-22 standard.
- **Size:** the FP2 is smaller than the original in every dimension, at 112.8 x 69.9 x 41.8mm, despite the upgrades.
- **Hot shoe protocol:** the new HU-21 unit speaks the same language as Panasonic and OM System flashes, widening strobe compatibility.
The pattern is clear: Sigma listened to six years of fp user feedback and addressed it point by point, without abandoning the modular concept that made the camera interesting in the first place.
## The price math
The FP2 launches at **$2,199 / £1,899 body-only**, available from November 11. Two kits are offered: **$2,749 / £2,399 with the EVF-21 viewfinder**, and **$2,749 / £2,419 with the 50mm F2 DG lens**.
Do the arithmetic on the kits and something interesting appears. The EVF-21 kit costs $550 more than the body alone, which prices the viewfinder itself at $550. The 50mm F2 kit also costs $550 over body-only, pricing that lens at $550 when bundled. Buy both separately and you would pay $1,100 in accessories on top of the body; Sigma is effectively letting you pick one $550 accessory at its standalone price and calling it a kit. There is no bundle discount, just a convenient single-SKU purchase.
At $2,199 body-only, the FP2 sits in the serious enthusiast to working-pro bracket: more than an entry full-frame body, less than a flagship. The value proposition is not the price alone but the price per cubic centimeter. Nothing else with a full-frame sensor and 6K video fits in a jacket pocket, and that miniaturization is what the $2,199 buys.
## A working photographer's take: what I would actually use it for
I shoot a Leica M11 with a 50mm lens, in natural light, no strobes. That is my instrument, and I am not shopping for a replacement. But I have spent 27 years around working photographers, and I know exactly where a camera like the FP2 earns its keep.
First, as a second body. On red carpets and at events, the shot you miss is the one your main camera was not pointed at. A 460-gram full-frame body that slips into a jacket pocket is a second angle you will actually carry, which beats the better camera you left in the bag. The 20fps burst and the tilting screen both serve this role: grab the overhead crowd shot, the low-angle arrival shot, without breaking stride.
Second, for hybrid assignments. Clients increasingly ask for motion alongside stills, and the FP2's 6K open-gate recording means one tiny body covers both. The L-mount is the quiet advantage here: the same lenses work across Sigma, Panasonic, and Leica bodies, so an FP2 can slot into an existing L-mount kit as the video specialist without new glass.
Third, for travel and behind-the-scenes. The original fp developed a cult following among filmmakers precisely because it disappeared into a carry-on. The FP2 keeps that footprint and adds the tilting screen the original lacked for low-angle video work.
The honest caveats: there is no built-in viewfinder, and the $550 EVF-21 pushes the real-world price to $2,749 for anyone who shoots eye-level stills. Battery life at 370 shots is modest, so budget for spares (at least they are the common Panasonic BLK-22 type). And 49 AF points is a modest count by 2026 standards, though the stacked sensor's readout speed matters more than the point count for tracking performance. I have not shot the camera, and nobody outside the launch reviewers has; treat the autofocus claims as unverified until independent testing lands.
## Who should buy it, and who should skip it
**Buy it if:** you shoot hybrid stills and video and want the smallest full-frame body available; you already own L-mount glass; you need a pocketable second body for events; you shoot video and want 6K open-gate without a cinema-camera rig.
**Skip it if:** you need a built-in viewfinder and do not want to pay $550 for the add-on; you shoot long days on one battery; you want the highest-resolution stills (24.5MP is versatile, not maximal); you are invested in another mount system and do not want to start over. For more on the resolution question, see our film film vs digital portrait comparison, and for getting the most from any small body in low light, our night photography settings guide.
The FP2 is not trying to be the best camera. It is trying to be the smallest full-frame camera that does everything, and on the spec sheet, it succeeds. Whether the autofocus and the real-world handling live up to the claim is the question the next month of independent reviews will answer. For now, it is the most interesting camera announcement of the fall, and the one I will be watching.
## Frequently asked questions
### When is the Sigma FP2 available?
November 11, 2026, at $2,199 body-only, $2,749 with the EVF-21 viewfinder, or $2,749 with the 50mm F2 DG lens.
### Is the Sigma FP2 really the world's smallest full-frame mirrorless camera?
That is Sigma's claim, and the dimensions support it: 112.8 x 69.9 x 41.8mm at 460 grams with battery and card. No other full-frame interchangeable-lens camera is smaller.
### What mount does the Sigma FP2 use?
The L-mount, shared with Leica, Panasonic, and Sigma lenses. If you already shoot L-mount, your glass works on day one.
### Does the Sigma FP2 have a viewfinder?
Not built in. The optional EVF-21 ($550 in the kit) adds a 5.76-million-dot OLED finder with 0.88x magnification. The LVF-21 turns the rear LCD into a loupe-style finder.
### How is the FP2 different from the original Sigma fp?
New partially stacked 24.5MP sensor, tilting touchscreen, 20fps shooting, 6K video, 70GB internal memory, bigger battery, and a smaller body. See the full comparison above.
### Is 24.5MP enough for professional work?
For events, editorial, and most client delivery, yes. It prints large, crops reasonably, and keeps file sizes manageable. Specialists in fine-art reproduction or heavy cropping may want more, a tradeoff we explored in our piece on what actually matters in a portrait camera.
