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
4K 3840x2160 29.97p 2820
Cinema 4096x2160 24p 3000
Cinema 3840x2160 24p 2820
4992x3744 29.97 3670
5184x3456 29.97 3800
5184x3888 - 3800

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