F number is a measure of the aperture (iris opening diameter) relative to the lens focal length.
for f = 50mm f/4 = 12.5 mm.
It has nothing to do with the camera - slr or otherwise.
The exposure equivalent might be affected if you have a built in ND filter.

Compared to the rx 10 1 inch sensor at f 4, if you use a lens on a full frame camera that would maintain the same angle of view, it would take f11 on a full frame to get the same depth of field, assuming filling the frame equally with the subject.

There have been some good suggestions made, especially that shooting the landscapes you like at Aperture Priority f/4 makes no sense. May I politely suggest that you try to understand the workings of photography better by reading or watching good quality videos on the Internet.
Your camera appears to be working just as designed. My experience with what people show me is that anything automatic tends to come up with choices I would never make. You really ought to have a reason for each setting and you can do that only if you understand what each does and then how to select a suitable combination. This, of course, leads to doing everything in Manual Mode.
Years at the front of classrooms on this and other subjects produced my mantra: Everything you know is wrong. Things that seem obvious to your own eyes are based on surface appearance. When you dig below the surface and come to understand the underlying concepts you come to realize why things were not turning out as you expected.
Study, experiment, experiment and then experiment some more. Learning is fun and satisfying.

The Olympus EM1x and EM1iii both have Live ND.

Hi...Thanks for the quick replies.
From your comments I have concluded I am a total idiot.
Id assumed the iso was set to auto 100-1600....which it always is. However on further inspection I find it is infact set to iso 1000.....Im desperately trying to think of a family member to blame...but Im having trouble finding one!
Cheers

We always blamed the dog. Oh, wait . . . . that was for something else.

Im grateful for the interesting replies here but I think some responses have missed the fact that my problem stemmed from the fact that somehow the iso setting had been changed.The camera is now working exactly as it has for the last two years.
If you know what your going to shoot, know when your going to shoot it, and have plenty of time, then full manual is probably the way to go.
Its not something I use much because most of my shots are done on the hoof, usually when Im travelling and time is usually of the essence.

Although you are not alone in believing in equivalent F stops for crop frame pictures, I do not.
That camera has a 220 mm zoom lens with a maximum aperture at longest zoom of F4. That is a real F4. For exposure purposes, it will be correct at F4 in the calculations. The 600 mm equivalent is a term of art that means very little except it's easier to understand than an angle of view. If the OP were to start using F8 in the belief that the equivalent F stop were meaningful it would guarantee a 2 stop error.
And some DSLR's are crop frame, btw.

Just as an aside, the Fuji X100V has a 4 stop built in ND filter in their fixed 23mm F2.0 lens.
This is true...However, the Op is referring to the Sony RX10 IV. A very different camera.
