Basically, you have the equivalent of 4 "frames" or panels of 1080.
Once you get to a 1080 "panel", the question is the same as for regular HD. Personally, I wouldn't zoom in much, if at all, into a 1080 frame.
I don't know if that sounds abstract, but it really is quite simple and straightforward when you start working with it.
I am on a phone, so it is hard to illustrate. But if you want to get a "feel" for how much you "zoom in" on different scenes, just take a HD frame and divide each measurement by 4. Then take each of the 4 panels as your maximum, equivalent "full frame" of 490x270, or whatever it comes out to.
I think if you try it visually it will make more sense. Good luck!

If you drag the 4k footage directly into the 1080p timeline, it should be scaled at 100% and already be cropped in, which would already be the max you'd want to zoom in without scaling past 1:1 pixel density. You'd have to scale down to 50% to "zoom out" so the 4k fills the frame. Right click on the clip in the timeline and make sure "Scale to Frame Size" isn't checked, as that'll resize the clip to your sequence dimensions and normalize the scale values so 100% fills the frame, which you don't want if you intend on using the 4k to crop in.

You can zoom in 2x while still maintain fill 1080p resolution. There are tons of native GH4 clips available for you to play around with in premiere pro.

Technically speaking it is 2x but in my experience with the GH4, I notice quality difference in the 1080p final product above about an 85% crop. No one else will probably ever notice, but I can see a slight difference about there. The image just starts looking a tad bit soft around the edges.
