I checked another topic, and I thought if I can set manyaspect frames with different cameras on same scene,,
so this is my suggestion for ds4.5 rc 4 or ds5,,
or new plug in for camera.
when I load new camera it keeps aspect frame lender setting .
of course we can change it when lendering.
but,if I can set some cameras with different aspect frame on the sceane,
I can use them for animation, more effective,,do not you think ?
eg default camera keep aspect 4:3
and canera 1 keep aspect 3:1 (point at figure1 face)
camera 2 keep aspect 1:5
if we toggle camera in view mode, the view change with aspect , (it may work when rendering animation, too)
and perspective view keep defaut aspect,,
it seems great,.
