Sigma FP2 records 32-bit float audio with Panasonic XLR kit

Sigma has announced the FP2, a full-frame L-Mount camera. The camera supports 32-bit float recording, which Sigma says reduces noise at low volumes and clipping at high volumes.

There is a condition. 32-bit float works only when the optional HU-21 hot shoe unit is attached and the Panasonic DMW-XLR2 XLR adapter or the DMW-DMS1 digital shotgun microphone is in use. The HU-21 follows the same hot shoe specification as OM System and Lumix cameras.

Formats and channels

Linear PCM runs at up to four channels at 96 kHz or two channels at 192 kHz, in 24-bit. The float option offers the same channel and sample rate combinations at 32-bit. The original fp recorded two channels at 48 kHz and 16-bit.

By default the camera records stereo audio on channels 1 and 2 from its built-in stereo microphone. An external microphone can be used instead, and adding one more allows four-channel recording, with devices assigned to channels 1 and 2 and to channels 3 and 4. In Auto mode the reference level can be set from +2 to -12. In Manual mode it moves from +6 dB to -36 dB in 3 dB steps.

Inputs and limits

The 3.5 mm stereo mini jack supports plug-in power and doubles as the timecode input. If the timecode input is set to the 3.5 mm terminal, the microphone on that jack cannot be used. If it is set to USB, USB microphones and headphones cannot be used.

The body has no headphone jack, so headphone output goes through USB. The camera has two USB-C ports. Port 1 is USB 2.0 and handles the viewfinder, audio, cable release and charging. Port 2 is USB 3.2 and handles SSD recording, webcam output and audio output, and also charges the camera. USB microphones can go into either port, but not both at once.

The FP2 is priced at $2,199 for the body. Sigma has set November 11, 2026 as the global release date.
