Parenting Offset boxSelect Origin or Target. When parenting a camera node, the image offset gets reset to the camera origin, which is not always the desired viewing option. Setting Parenting Offset to Target restores the image to the default viewplane distance relative to the camera. The offset value is computed from the default camera field of view and the default image size, and does not change, even if other camera parameters are changed. This value is displayed in the Parenting Offset field.

Roll fieldDisplays the amount of camera roll, in degrees. A positive value rolls the camera clockwise, and a negative value rolls it counter-clockwise. This field is available only with the Aim, and Aim and Up cameras.
