A7S II importance of resolution for 4K export

[flo.nick]

Hey Sony Alpha community,

 

I am planning a landscape timelapse project in British Columbia for this summer and I have a Sony Alpha 7S II. I know that all the good landscape photographers out there use the A7R II or a camera with similar resolution for landscape photography.

 

In my case, though, I will export a 4K video file for which my 4240 × 2832 still image size of the A7S II should be enough. I will not print my photos in large formats like most landscape photographers.

So my question is, how important is the resolution of my camera when shooting a 4K timelapse video? What is the difference in the final image quality when exporting a 4240 × 2832 (A7S II) image file in 4K compared to exporting a 7952 x 5304 (A7R II) image file in 4K? What really matters is the resolution of your export, or am I wrong?

 

Of course I understand that using a A7S II over an A7R II will limit my ability to crop in the image while still keeping enough resolution.

 

I hope you guys understand my problem and can help me.

 

Cheers,

Flo
