Seven years after the original fp, Sigma has introduced its successor. The Sigma FP2 keeps the brick-shaped, modular concept, but almost everything inside has changed: a new partially stacked full-frame sensor, 6K open gate recording, ProRes RAW instead of CinemaDNG, and a tilting screen. Sigma again calls it the world’s smallest full-frame camera body. Here is what filmmakers need to know.

The Sigma FP2 is an L-Mount camera built around a 24.5MP partially stacked 35mm full-frame CMOS sensor (35.9 x 23.9mm). It records 6K open gate (3:2) video at up to 59.94fps, and Apple ProRes RAW HQ or ProRes RAW (12-bit) at up to 6K 29.97fps. H.264, H.265 and Leica’s L-Log are also available, and Sigma claims up to 14.1 stops of dynamic range in 4K full-frame L-Log. The camera has 70GB of internal storage in addition to an SD card slot and SSD recording over USB, 32-bit float audio with an optional accessory, phase-detection autofocus with subject detection, a tilting 3.15in touchscreen and a new BP-91 battery rated for about 130 minutes of video. The body measures 112.8 x 69.9 x 41.8mm / 4.4 x 2.8 x 1.6in and weighs 376g / 13.3oz without battery and card. The Sigma FP2 is priced at $2,199 / €2,199 for the body, and Sigma has set November 11, 2026 as the global release date.

From fp to FP2

Note the name: Sigma writes the new camera as “FP2” in capital letters, while the original Sigma fp from 2019 and the 61MP fp L from 2021 used lowercase letters. The concept stays the same. The FP2 is a small, flat body without a built-in viewfinder or grip, and users add a grip, viewfinder, hot shoe or cage as the job requires. A switch on the top plate toggles between STILL and CINE modes, and each mode has its own interface and settings.

Compared to the original fp, the FP2 is 3.5mm thinner (41.8mm against 45.3mm) at practically the same width and height. The body alone is 6g heavier at 376g. With battery and SD card, it weighs 460g / 16.2oz, against 422g for the fp. The FP2 keeps a dust and splash resistant construction, and Sigma builds it at its factory in Aizu, Japan.

The fp series has a loyal following among filmmakers, and the community has kept the original camera alive with firmware projects. Only a few weeks ago, we reported on an open gate hack for the Sigma fp that records 3K 3:2 CinemaDNG from the full sensor to an external SSD. The FP2 now does open gate officially, at 6K, with no hack required.

6K open gate and ProRes RAW

The headline video feature is 6K open gate recording, which uses the full 3:2 area of the sensor. Sigma positions this for productions that deliver in several aspect ratios, including vertical versions for social platforms. Video aspect ratios are 3:2, 16:9, 17:9 and 4:3.

Frame rates break down as follows. 6K records at 23.98, 24, 25, 29.97, 47.95, 48, 50 and 59.94fps, but electronic image stabilization (EIS) is not available in 6K. ProRes RAW HQ and ProRes RAW stop at 6K 29.97fps, so 6K above 30fps is limited to the compressed codecs. 4K offers the same frame rates up to 59.94fps, with 100 and 119.88fps in crop mode. 2K goes up to 119.88fps in 16:9 only.

The codec choice marks a clear change from the original fp. The fp recorded 8, 10 and 12-bit CinemaDNG internally, plus 12-bit RAW over HDMI to Atomos and Blackmagic recorders. CinemaDNG is not in the FP2 specification sheet. Instead, the camera records Apple ProRes RAW HQ and ProRes RAW internally. For log workflows, Sigma uses L-Log from Leica Camera AG, which is supported by most grading applications. A ProRes 422 option is not listed in Sigma’s specifications.

Recording media options are the internal 70GB memory, SDXC cards (UHS-II supported) and portable SSDs connected over USB 3.2 with bus power. Sigma says the internal storage supports high-speed writing and lets recording continue when the card is full. Continuous recording is limited to two hours.

What about dynamic range?

Sigma claims up to 14.1 stops of dynamic range when recording 4K full-frame L-Log. The company also states that the camera has seven stops of highlight headroom above middle grey at ISO 1250 and above. In Log and RAW, the FP2 has dual base ISOs of 1250 and 10000, with a range of ISO 1250 to 102400 (expandable down to ISO 320 and 640). In standard MOV recording, the base ISOs are 320 and 2500.

These figures are manufacturer claims, not measurements. For context, our lab measured about 11.3 stops (at SNR = 2) for the original fp in 12-bit CinemaDNG, and about 11 stops for the fp L in our lab test. Readers should keep the different methods in mind when they compare a spec sheet number with a lab result.

Rolling shutter and autofocus

The FP2 has an electronic shutter only, as the fp did. Sigma says that the partially stacked sensor has a high-speed readout that significantly reduces rolling shutter distortion, but it does not give a readout time. The original fp measured 20.8ms in UHD in our lab, and the fp L measured 21.7ms in full-frame 4K. Stills shutter speeds go from 1/25600 to 30 seconds, and the flash sync speed is 1/50 sec. (1/60 sec. in crop mode).

Autofocus is a big area of change. The fp relied on contrast detection, which was one of the main limits of the camera for run-and-gun work. The FP2 combines on-sensor phase detection with contrast detection, and subject tracking recognizes humans, dogs, cats and birds, with eye AF. Focus ring control can be set to linear or non-linear, which matters for manual pulls with modern autofocus lenses.

Audio, timecode and connections

Audio recording is now Linear PCM at up to 4 channels at 96kHz or 2 channels at 192kHz in 24-bit, or 32-bit float at the same channel and sample rate combinations. The fp recorded 2-channel 48kHz 16-bit audio. There is a catch for 32-bit float: it works only with the optional HU-21 hot shoe unit attached and the Panasonic DMW-XLR2 XLR adapter or the DMW-DMS1 shotgun microphone. The HU-21 uses the same hot shoe specification as OM System and Lumix cameras.

The 3.5mm microphone input doubles as a timecode input. There is no dedicated headphone jack on the body; headphone output goes through USB. The camera has two USB-C ports. Port 1 (USB 2.0) handles the EVF, audio, cable release and charging. Port 2 (USB 3.2) handles SSD recording, webcam (UVC) and audio (UAC) output, and charging. A full-size HDMI Type A port (version 2.1) completes the set. Sigma does not list RAW output over HDMI for the FP2.

Other features include Gyroflow support for stabilization in post, a webcam mode, waveform, histogram, zebras and false color, and settings that can be saved and loaded with a QR code.

Tilting screen and new viewfinders

The original fp had a fixed rear screen. The FP2 has a 3.15in touchscreen with about 2.1 million dots that tilts up by 90° and down by 45°, which helps with low-angle and high-angle work without an external monitor.

The new Electronic Viewfinder EVF-21 connects to the camera with a single USB-C connection and tilts upward by up to 90°. According to B&H’s launch text, it uses a 0.5in OLED panel with 5.76 million dots. Sigma also introduces the LCD Viewfinder LVF-21, which sits over the rear screen and gives an on-axis view.

The Director’s Viewfinder function is back and adds current cinema cameras. It simulates the frame of the ARRI ALEXA 35 Xtreme, ALEXA LF and Mini LF, ALEXA Mini, AMIRA and ARRICAM / ARRIFLEX, the Sony VENICE, VENICE 2 and BURANO, and RED cameras such as the V-RAPTOR XL [X] and KOMODO X. Anamorphic desqueeze is available at 1.25x, 1.3x, 1.33x, 1.5x, 1.6x, 1.65x, 1.8x and 2.0x. On the fp and fp L, Sigma added and extended this function through firmware, most recently with the fp and fp L firmware updates we covered in 2023. On the FP2, it is part of the camera from day one.

Battery, power and accessories

The new Li-ion Battery Pack BP-91 replaces the BP-51 of the fp series. Sigma rates it at about 370 still images or about 130 minutes of video, approximately 30% more than the original fp. The camera can also run on USB Power Delivery (Sigma recommends an adapter with 27W or more) or on the new DC Connector CN-91.

Sigma lists these optional accessories: Hand Grip HG-11, Electronic Viewfinder EVF-21, LCD Viewfinder LVF-21, Base Plate BPL-21, Hot Shoe Unit HU-21, Cable Release CR-51, Battery Charger BC-91 and DC Connector CN-91. Note that the hot shoe unit is now an optional accessory. A pouch, battery, strap and SH-11 strap holder are in the box.

Stills and color modes

For photographers, the FP2 shoots 14-bit lossless compressed DNG and JPEG at 6016 x 4012 pixels, with continuous shooting at up to 20fps for up to 200 JPEG or 180 DNG frames. Stills base ISOs are 320 and 2500, with a range of ISO 100 to 102400 (expandable down to ISO 6). There is no in-body stabilization; EIS is available for video only.

A dedicated Color button gives access to 13 color modes: Standard, Rich, Calm, Powder Blue, Warm Gold, Teal and Orange, FOV Classic Blue, FOV Classic Yellow, Forest Green, Sunset Red, Cinema, 709 Look and Monochrome. Several of them come from the fp series. Sigma says the 709 Look mode is based on the Rec.709 standard and gives natural, understated tones, which can be useful as a baked-in look for fast turnaround work.

Price and availability

The Sigma FP2 body costs $2,199 at B&H. B&H also takes pre-orders for the kit with the EVF-21 viewfinder at $2,749, with an estimated ship date of November 11. Sigma also offers a kit with the 50mm F2 DG Contemporary lens. In Europe, Sigma Germany lists the body at €2,199 including VAT. CVP takes pre-orders for the FP2 kits with the EVF-21 and with the 50mm F2 lens. Sigma has set Thursday, November 11, 2026 as the global release date.

For comparison, the original fp launched at $1,899, and the fp L costs $2,499 at B&H. At $2,199, the FP2 adds 6K open gate, ProRes RAW, phase-detection AF and a tilting screen for $300 more than the fp did at launch. For more details, see the Sigma FP2 product page.
