How is variable zoom done?

[Stublerone]

I have to say that I am using trackIR and priority is not this zoom for me ( i have als different ways to make it work with t.a.r.g.e.t. or foxy on my tm warthog).

But main fact is that the zoom of the"free view" is not coordinated with switching into gunsight mode (with shift+f1 right???). Means, that i always fully zoom in the "REVI" and also get the limted viewing angle in this mode. So, if my enemy makes turns and rolls, I am stuck in this limited view. So I have to press "shift+f1" again to release this view. At this point at the latest, I get back into the old zoom from before and it makes weird movement, as you are already looking in a harder angle than allowed before in the gunsight view. I lose my enemy everytime, when I do this or even when i forget to release the view.

Am I playing with the wrong keys? I just heard others, who agreed with me in that point. So I am currently thinking, that it is like I described. Everybody feel free to help out, comment or even to vote in the tracker, if i am right!
