You don't need 2.1 to adjust the FOV - it's right there in the screenshot you posted - "horizontal fov" (I generally don't mess with vertical fov). Just increase the horizontal one, and it mimics the wide field of view that a wide-angle has. Also as a bonus, because TG2 doesn't have depth of field built in yet, the infinite depth of field is closer to what a wide-angle would produce anyway.
