Weird Camera move

Another day, another problem :smiley:

This time when i try to move forward camera (like here: https://www.youtube.com/watch?v=3vtymxlhH0c&feature=youtu.be), it move really weird from left to right instead of moving straight forward.

I think maybe it s something i can change in functions tab but it’s way to far and i can’t zoom in this fragment.

Please help
