4K crop on FZ1000
I was looking at some info on the FZ1000 and discovered that it has a substantial crop when shooting 4K video. Instead of a 25-400mm lens it becomes a 37-592mm lens. Great for more tele, but bad for wide angle. Is this true? If so, is it a big problem? I think that it would be a major problem for shooting stills, but is it less so in video? What do people do to compensate? Thanks.
