I need no perspective distortion for some part of screen

Hi mates!.

I need that when I instance an object (above or below in the screen) not to be affected by the distortion of the perspective of the camera.

How could I do this?. The object follows with me as an indicator.

Maybe the combination of layers?. I don't know the exact purpose of the layers, but I suppose that this is not the objective of the layers because I thought that I could divide the screen for the camera in two parts: one for a normal perspective with its FOV and distortion and another one for isometric perspective which will render without distortion for the above part of the screen.

I don't like the distortion of my objects produced in the first plane when they go with me .

Please, help me.
