[Closed] Camera orthographic FOV

Hello
I have got question. I am trying to export Camera from blender to 3ds max.
Collada isn’t working as it should do(In my opinion).

When I am exporting perspective camera there is no problem

I have problem when I am trying to export orthographic camera

In Blender (when we are using orthographic camera) everything depends on ortho_scale.
In Max there is no such value.
Everything depends on FOV value all the time.

I was trying to compare that value.
Blender ortho_scale=2.667 looks similar to Max Fov 0.995
It doesn’t look ideal. Furthermore it is not linear function probably.

Maybe someone tried to do something similar? From another soft?
