Freelook Issue:
Sight in your weapon, press and hold Freelook key, move mouse around.
Now unsight your weapon and use Freelook. Notice how Freelook only works when weapon is not sighted.
Binoculars:
Select Binoculars and notice how the player uses to immediatly, and when zooming out, the player puts the binoculars away.
I prefer the option of the player just taking the binoculars out and holding them in his hands. When I want to zoom, I press the alternate mouse key to actually use them, and pressing them again would bring them back down. Finally, pressing binocular key will make the character put away the binoculars.
