Camera.fieldOfView

説明

度単位でのカメラの視野。

This is the vertical field of view; horizontal Field of view varies depending on the viewport's aspect ratio. Field of view is ignored when camera is orthographic (see orthographic).

Some VR SDKs have fixed field of view values that are used for VR cameras. When VR is enabled with those SDKs, this property will always return the value from the SDK. You will see a warning logged if you attempt to set the property and the value will be ignored.
