well I was going to try to take some screenshots of the differences but the weirdest thing happens. the screenshots basically come out the same. dials are round in both setups. the horizontal fov is the same and there is a small difference in the vertical fov. anyhow I am satisfied with the setting I have. basically in a6m5b the horizontal field of view extends to the root of the cannon/wing and vertically it extends to to right above the 3rd hoop in the canopy.
