Why are my cameras inconsistent?
 
 
 

If you import a Maya camera into 3ds Max using a Fit Resolution Gate setting of Vertical or Fill, the results will differ.

For better support between Maya cameras in 3ds Max, set the Fit Resolution Gate setting to Horizontal, rather than Vertical or the default, Fill.

NoteYou can import 3ds Max cameras into Maya with no difficulty; Maya renders the same result.
