I decided to try my Fujinon XA55 Digipower lens with a Panasonic GH4. It worked surprisingly well. Everything is shot in UHD, 25p. All camera settings is set to default. Standard gamma and color settings. Since I couldn't use ND-filters, I had to use shutter speeds around 1/200 in the sunlight.

Incredible video showing both the zoom range and optical quality of Fujifilm's awesome Fujinon Digipower XA55.
