Sigma has announced a firmware update to their full-frame FP mirrorless camera, which includes false color and linear/non-linear focus ring control for supported lenses among its other featured benefits. But there are other new features and fixes that make this update worthy of user attention.
The Sigma FP is a full-frame mirrorless camera capable of capturing 12-bit 4K video up to 30fps. It uses CinemaDNG but can also record in 8-bit 4:2:2 in All-I and GOP H.264. The sensor offers a 35mm equivalent crop factor of 1.5x.
Chief of the update features is adding the false color status to the on-screen data, showing exposure in different colors, and allowing users to view that status in the frame.
False color can be beneficial in dialing in the exposure settings and showing when certain parts of the image are clipping, when a first glance may miss it without it. In addition, the False Color setting can be assigned to a custom button function, so it’s available quickly.
For the Focus Ring Control, compatible lenses can now be switched to either linear or non-linear configurations, enabling the photographer to finely focus with better control.
Under “non-linear focus,” the amount of focal point movement varies depending on the rotational speed, but when used in linear mode, focal point movement remains constant. Sigma points out that compatible lenses may also need a firmware update for this feature to work effectively.
With Still/Cine Link settings, users can select to link a key exposure setting from Still to Cine modes. Nice feature if you’re looking to grab some video at the same time and don’t want to waste time resetting the camera. The link setting will also impact Shooting Mode, Shutter Speed, Aperture, Exposure Compensation, and ISO Sensitivity.
Other features of the FP4 update include:
- Changing the specification so that the countdown before a shot in self-timer mode (2 seconds and 10 seconds), and the exposure time for long exposures (bulb shooting and exposures of 1 second or longer) are displayed on the screen.
- Adding a function in STILL mode where information from the attached lens (focal length and shooting distance) can be displayed on the screen.
- Adding a “Clip Numbering” function in CINE mode that allows users to change the clip numbering of the “File name / Number” in the “SYSTEM” menu.
With the FP4 update, Sigma warns it’s a good idea to update any other firmware which the FP camera may interact with. Chief of which, the update may cause an issue when using Blackmagic’s Video Assist monitor recorder, which has had performance issues under the firmware update. Blackmagic has released “Video Assist 3.5.2 Update” to address the issue.
The Vs. 4 firmware for the Sigma FP Mirrorless camera can be updated from Sigma’s Support Website. It is also suggested to update while the camera battery is either fully charged or when the camera is connected to an AC Adapter.
