The Panasonic GH5 is well known to be a great camera for video and I can confirm that see my latest videos
Clearly the camera is fantastic and with the right set up that I will cover in future posts it takes amazing video.
I wanted to start however from photography as the GH5 also takes great still images.

First and foremost macro. In general terms the lens choice of other micro four third also applies to the GH5 so my favourite lens is the Olympus 60mm. Alternatively if you don’t have that lens and you don’t have extremely small subjects you can get good results with a zoom lens I use the Pana 14/42 MKII but other work well too.

In terms of arms strobes nothing changes so my current rig is based on a Nauticam NA-GH5 housing and two Inon Z240. I have each arm set with 1x 8″ and 1x 5″ arm segments you will notice that the longer arms is closer to the camera this because in macro you will usually shoot above the sand so this makes it easier.
For wide angle the situation changes slightly as I use a 12″ arm segment as in the rig below.

For wide angle the arms return to a standard situation with shorter segment close to the housing. The same configuration applies if you shoot the 8mm fisheye.
In terms of floatation the GH5 housing is heavy with the 35 macro port is 720 grams and with the fisheye 620 grams. For macro I like my set up to be negative so less floats . For wide angle in case you take slow shutter speed shots I also use the tripod kit for the NA-GH5 this is not as good as a complete tripod but works well in wrecks
In the next posts I will talk about video as here there is a question about diopters and which ones do I use. Lights is also a topic of contention and will discuss few options there too
As always please ask questions if you wish
