This is 30x, 10 levels Sniper Zoom config of mine for extendedZoom mod (included). Best for hunting bugs on enemy tank from 500m distance =)
It also includes No Blackout in sniper mode and allows you to un-zoom to 300 meters.
How to install:
Extract archive into the root folder of the game (with overwrite confirmations).
