Trouble zooming with sniper

[The Old Dude]

Hello everyone,

I have the following problem : I've just upgraded my sniper rifle with the long range scope.
In the shop menu, it's said that I have to hit the "F" key to change the zoom.

But when I try, nothing happens. The "F" key is actually bind to close combat.
When I try mousewheel, it just switch between grenades and molotov cocktail...

Do you have any idea how to solve this problem ?
I can't find any "zoom" key in the binding option menu.

I'm kinda lost here.
Any help would be really appreciated :)

Scroll mouse wheel is default/hold right mouse button then scroll it zooms in or out, go to options and bind the keys where you want them to be.

Ps, some scopes don't have zoom

Have the weapon zoomed in, then scroll to change the zooming distance. As long as you haven't changed anything in the option related to this it should work!
