Panasonic Lumix GH5 and Sigma 4.5mm fisheye

The following documents the various video modes on the Panasonic Lumix GH5 along with the fisheye circle using the Sigma 4.5mm f2.8 fisheye. Not all modes are tested, for example, 8 bit colour and HD or under is available on a number of cameras. The modes tested were those above HD resolution and 10 bit colour.

In the table that follows, the fisheye circle diameter is listed for 8 video modes and the still photograph mode. The degree of cut-off can be estimated from the same image.

Mode	Image size	Frame rate	Fisheye circle	Sample
Anamorphic	3328x2496	25p	2440
4K	3840x2160	25p	2820
4K	4096x2160	23.98p	3000

PhotoMode 3x2	5184x3456	29.97	3800
Still Time-lapse	5184x3888	-	3800

The 8 bit recording modes have the equivalent circle as their 10bit resolution counterparts, in some cases with higher frame rates.
