I want to buy a nice camera, and im looking at the panasonic GH4 because the 4k video looks great and i have seen some movies done with it that look nice. but i see its 16MP? for a new camera? and i see other cameras at 24MP or 36MP... wouldn't higher MP be the best camera? why dont higher MP cameras take good video? or do they? i dont know much so i wonder why so many prices for so little MP... and some good video and others good Pics? any help answering why cameras are like this would be cool
