Thing is. Zoom is a bit inconsistent right now. For instance, if you can clearly see it on this screenshot:
As you can see base terriority has greater elevation therefore you can see how much bigger pio on left is, beach on the other hand has lower elevation and look how small pio on the right is. This is max zoom out. Its actually a thing for 1v1 map, 2v2 maps have normal zoom level across the board.
I belive in SP alpha cameras min\max zoom was actually changing dynamicly based on the elevation, but it was super fiddly, with camera jumping around. At least it looked awful druring first preview, because even small elevation changes affected the camera.
As for the zoom, I think its in the right spot anyway. But if anything, there at least should be min\max elevation parameter, so camera would only be affected in drastic situations like on mentioned 1v1 map.
this is it.
coh3 has supposedly combat designed around more elevations. you need a farther camera to represent said elevation.
that said, the default zoom level in coh3 may discomfort coh2 players used to a closer fov.
a simple mouse wheel scroll to zoom in, and boom. you get your closer battlefield camera back.
i guess relic can have an option settings to default your prefered zoom levels
