Games often widen the FoV when sprinting (or boosting or whatever verb applies) because the stuff at the edge of your screen really zooms by and makes it look like you're going faster. What probably happened in Far Cry was they had some stupid narrow FoV like 65 degrees and bump it up wider when sprinting, then when you stop sprinting it goes back to 65 which overrides the wider angle that parent commenter had set.
