Camera.usePhysicalProperties

説明

Enable usePhysicalProperties to use physical camera properties to compute the field of view and the frustum.

The physical properties include the sensor size, lens shift, and focal length.

using UnityEngine;

public class ExampleScript : MonoBehaviour
{
    void Start()
    {
        Camera cam = gameObject.GetComponent<Camera>();
        cam.usePhysicalProperties = true;
        cam.focalLength = 60f;
    }

}
