I got zoomed out in valley of titans in act 2 and it did not revert back for the whole session

I play on widescreen and it seems that I got zoomed out when I approached the 3 heads in the middle, and it did not zoom back when I played with my friend

Attached image, where it shows me on the right and friend on the right.

He is standing in location where he could just barely see and you can notice that I see way beyond him.

What happened :
- we loaded into Valley of Titans
- 3 heads were close to the entrance, so as we moved we got instantly zoomed out.
- we moved away from the area, my friend got zoomed in again, and mine got stuck as I was close to the edge of the map.

not sure if this is reproduceable.
