I've been playing with the wife's Panasonic FZ2000. Actually trying to familiarise myself with it, such that when she says 'it's not working properly' in the middle of nowhere, I have a fighting chance of sorting it out.
Specifically I have been looking at video settings and came across 2 effects that I don't understand. So you video experts please explain ....
When I set her camera to still photography the zoom range in the viewfinder is 24-480.
If I switch to 4K video the zoom range changes to 37-740. It visibly zooms in the viewfinder. I don't understand why it's doing that? I thought 4K had more pixels? Surely zooming in changes that?
I then wondered how it was achieving that zoom. Was it optical or digital? As we know digital zooms are always inferior to optical zooms. How could a superior format use inferior zooming?
But here's the thing... when I take a frame grab from a 4K video, the image quality is just as good as a standard still shot.
So the 4K zoom effect has given her 50% more reach without quality loss.
I should add that this camera can actually take 4K still photographs without the need for frame grabbing a video when we would expect to have motion blur issues in some frames. But I thought I would try the worst case scenario and just grab a frame. And it was fine.
Don't understand
