without zoom I cant aim and hit at any target, hardly see the planes at 400 yards, but with zoom I cant follow moving targets.
So, what about having zoom only with frontal view? that is:
You switch on the zoom and, until switched off, you will have zoom automatically activated in frontal view and deactivated for anyother view. That way you'll be able to follow maneouvering planes getting out of your frontal view and shooting at them as soon as you re-align your frontal view with them.
Also, two levels of predefined zoom would be welcome.
Perhaps, another key could be configured to activate zoom with any view.
