Perspective Camera without distortions

Is there a way of creating a perspective camera so that objects on its edges do not get distorted (stretched). I don`t want to use Orthographic.

Is there a solution? Is there any setting of the Perspective camera which is responsible for distortion at the edges?

The easiest “fix” is to narrow the field of view of the camera and then change the distance from the camera to the objects. The narrower the camera’s field of view, the less distortion you will see. You cannot get rid if it completely, but you can largely mitigate it.
