I take a look at Multicam.systems adaptation of BlackMagic Design's B4 adapter for URSA- which Multicam Systems has adapted for use on M43 cameras. It enlarges the circle of light co cover a wider area which can be of use on some "windowed" sensor Micro 4/3 cameras.
I test it on the full M43 sensor using two GH4 camcorders in HD mode (not cropped 4K mode) and while you can see the increase in size, and the good optical quality it delivers, the GH4 is not the camera it is designed to serve- so it still doesn't cover the whole sensor. But using the larger sensor area enables me to show the difference between a 2.3" lens, with and without the optical adapter.
