The difference between IASE and IRSE. The difference is the remote focus servo control that the iase has and the irse does not. The purpose of this control is to allow the lens to be mounted on a jibbed camera, to give the operator control of the focus when the cam is not on his/her shoulder. The irse has remote zoom control only to be used on shoulder/tripod.
