The Panasonic Lumix BGH1 is a strange camera if you are used to DSLR or Mirrorless camera body styles. It is tiny and full of connections with no screen unless you provide one via a computer that is tethered or an HDMI field monitor. It uses the same dual ISO sensor found on the Panasonic Lumix GH5s which is a very good low light camera in a Micro 4/3ds package. The BGH1 has a better internal recording set of options than the GH5s but it is more intended as a tethered studio solution with the addition of Genlock synch and SDI out.
The camera also has VFR or a Variable frame rate mode which is identical to the Lumix GH5s as it records from 1fps to 240fps in Full HD 1080p and delivers pretty good performance up to 200fps then lowers the quality along with providing a small added crop to the image at 225fps and 240fps. It is still not as sharp as regular 1080p video and the codec is saved at a lower bit rate but having 240fps as an option is great.
