Change FOV to have zoom/binacular effect

Hey, I was wondering if there is a way to change the FOV. Regular camera settings seem to be ineffective, which is reasonable as I guess Oculus doesn't want those to be altered for the 99% of the projects. But I saw that their new game, Phantom: covert ops uses a similar approach for scoped sniper rifles, so there is hope. In my case, I would like to mimic regular binaculars.
