The sugestion of Camera Settings

[tkbd]

I felt also other inconvenience in the process of performing a set of Pov-Ray export.
Wings3D's Menu: View > Camera Settings...
Negative Size preset is less (exist only two aspect ration).

Quote:-------- In currently -------------------
24 × 36 mm [3:2] : Fullsize : Leica size, 135 film
60 × 60 mm [1:1] : 120 film
"Custom"
In set "Custom" ,but it doesn't change put the other numbers.

For example, is it necessary lenses, such as the following?

Quote:45 x 60 mm [4:3] : 120 film 645 format
34 x 60 mm [16:9]

Also an another sugestion,
Is it possible to confirm the change of the camera view in real time?
This will help users to understand changing of view.
