You have you camera projection as Perspective and it is a natural behavior of what is happenening. Switch to Orthographic and you will get the result you expected, however you might see your object smaller or bigger depending the Field of View . But note that Orthographic cameras are best for 2D / 2.5D games and you might need to use Perspective projection. Please comment and specifcy more details for a more detailed explanation. Hope it helps!
