Next adjustment is in the XY plane from the X axis. Again I did a hide to view the geometry better. Your view point should now look similar to this one. These are the Distance, Zoom, Twist and Clip features. Zoom and Distance work hand in hand much like a lens of a camera.
Zoom sets the focal length like a camera lens.
The default is set to value of 50 which is a standard corrective perspective value. Through some experimentation, try adjusting the zoom value to 25 then to 75 and you'll see the point. A Zoom value of 25 will seem like a fish eye lens while the value of 75 starts to look like a telescopic lens. This is where you need to play with Distance. With a Zoom Value of 25 set, adjust the Distance value to 350 to correspond.
