When Sigma released its first mirrorless 4K camera using a back-illuminated Bayer CMOS sensor, the biggest (or smallest) thing it had going for it was its size. The fp is one of the smallest full-frame cameras on the market today, but when you dive deeper into its feature set, you begin to notice an older CinemaDNG codec and internal data rates limited to 8-bit. The release seemed to fall short when comparing it to competitors.

However, because of its size, L-mount compatibility, and scalability for larger productions, the camera had potential if certain things were addressed via firmware. Today, Sigma has done that and more with a major update in firmware 2.0.

The fp is now able to record 12-bit 4K UHD at 25p and 29.97fps as well as 12-bit full-HD at 100p, 8-bit full-HD 100p, and 8-bit full-HD 120p. Additionally, the camera supports 12-bit 4K DCI over HDMI RAW. And Sigma didn't stop there.

The company added Apple ProRes RAW via Atomos and Blackmagic RAW support over HDMI, which will require updates on the recorder side, but the Sigma fp now supports ProRes RAW, BRAW, and CinemaDNG. On top of that, Sigma added a dual base ISO feature at 100 and 3200. There is also a new HDR recording feature as well as Cinemagraph creation and playback.

Viewfinder_0Sigma fp Director's Viewfinder mode

One interesting function of the Sigma fp is its ability to act as a Director's Viewfinder. In our review, it was noted that it would be great if you could record video and take stills while using it as a viewfinder. Sigma has added that functionality as well.

Sigma also improved its autofocus, added timecode to the 3.5mm microphone input, and add an "off" option in color mode. The fp still doesn't have a log recording mode, but the added off mode and addition of RAW formats should provide decent latitude options. The full list of updates is below.
