With the 4k crop the GH4 will be useless with the 14-42mm bare port unless you only shoot close ups
"Useless" is a rather wild statement and quite incorrect.
At the wide-end behind a flat port, the 14-45mm makes a good MS lens. For example, recently in Komodo, I was able to get some footage of the whole body of a very large octopus by pulling back to about 1.5 meters away and, from 2 to 3 meters distance, I was able to shoot the octopus sitting on a coral head. So with the flip diopter, one lens was able to give me CU of the octopus eye, a wider CU of its head, its entire body and its environment.
Not what I'd call "useless".
