Trouble with logic related to my camera smoothing

I'm having trouble with the logic related my camera. I'm trying to make the camera smoothly transition between an "aiming mode" and a "regular mode" based on player input. I don't want the camera smoothed when the camera has finished smoothing. Here is the related

 /// <summary>
     /// Sets the camera position based on whether or not the player is in aiming mode.
     /// </summary>
     void HandleCameraMovementBasedOnMode(bool isInAimingMode)
     {
         // Camera is where it is wanted for aiming
         if(isInAimingMode == true && camIsInDesiredAimPos == true)
         {
             desiredPos = target.position - transform.forward * aimingDstFromTarget + Vector3.up;            
             transform.position = desiredPos;
         }
 
         // Cam is not where we want it for aiming
         else if(isInAimingMode == true && camIsInDesiredAimPos == false)
         {
             desiredPos = target.position - transform.forward * aimingDstFromTarget + Vector3.up;
             Vector3 smoothVector = Vector3.SmoothDamp(transform.position, desiredPos, ref posTransSmoothVelocity, posTransSmoothTime);
 
             transform.position = smoothVector;
 
             camIsInDesiredAimPos = true;
         }
 
         // Cam is not where it's wanted for normal mode
         else if(isInAimingMode == false && camIsInDesiredAimPos == true)
         {
             desiredPos = target.position - transform.forward * normalDstFromTarget;
             Vector3 smoothVector = Vector3.SmoothDamp(transform.position, desiredPos, ref posTransSmoothVelocity, posTransSmoothTime);
 
             transform.position = smoothVector;
 
             camIsInDesiredAimPos = false;
         }
 
         // Cam is where we want it when not aiming
         else if(isInAimingMode == false && camIsInDesiredAimPos == false)
         {
             desiredPos = target.position - transform.forward * normalDstFromTarget;
             transform.position = desiredPos;
         }
     }
