This is 30x, 10 levels Sniper Zoom config of mine for ZoomX mod (included). Zoom level indicator.
Best for hunting bugs on enemy tank from 500m distance =)
If You prefer version with No Scroll switching between modes, look for file named SMOOTH_ZOOM_xxx_NS in Other Downloads section.
How to install:
Extract archive into the root folder of the game (with overwrite confirmations).
