If camera is higher than 64 meters (my scale is 1.0, so it is 64 units) above XY plane and lower than 256, then it behave badly and mistreats lenses. See that zoomed in circle in the center, it should not be.
upd: in a scene with unit scale 3.0, its 17 meters where camera produce that circle.
upd2: there's some complex correlation, numbers 64 and 256 seems to be valid only for attached scene.
And a little further z than 256:
I think this also happen with negative z values.Orthographic camera misbehaviour

Re: Orthographic camera misbehaviour
The addon for Blender 2.79 is no longer maintained. Does the problem also happen with Blender 2.82a?
Re: Orthographic camera misbehaviour
Yes.

Re: Orthographic camera misbehaviour
I can't say anything about the z-issue, but another thing about your lens setup wasd:
When you simulate a lens setup, you should use a thin cube of matte transulcent material as a "detector" (or "sensor"), end observe this detector from behind with a camera. If you use just a camera, you will essentially get a zero-size aperture image (depending on camera settings like DOF, but somehow it does not behave like I expect, also with the perspective camera).
See a modified file attached. The deetctor is just placed roughly in focus. I moved all the objects around a bit in the process (like also the checkerboard) of figuring out whats what, so don't be surprised. here is the result. You can now also see vignetting in the corners:
For some reason, the "Detector" needs to be a thin but not too thin object to work reliably. If I set up a test scene from scratch with just one lens etc, a simple matte translucent plane works also, but it didn't in this file
