3-D character/shape to NOT stretch?

[Blackhawk1]

How do I get a 3-D character to NOT stretch out of shape when moving toward the edges of the animation window? Every character or shape I have in ASP stretches like it's being viewed through a fish-eye lens the closer it moves away from the center of the stage. Any way to get this to NOT happen without selecting "Immune to camera movements"?

Select a longer camera lens. Camera zoom tool (6) has a default of 60, a smaller number means a longer (tele) lens. Adjust camera position Z value.
