With the invaluable help of Erik (modification) and Bjørn (parts) I have recived this two lenses in time for Christmas. They have undergone a tight and clean conversion and now they meter in any mode, data is automatically stored and aperture can be set from the aperture ring or from the dial -if so desired- as D type lens do, setting it to the minimum aperture and controlling form the camera.
Thank you both
P.E.: just to round it up, the images have been taken with a el-nikkor 80mm 5.6 with the helicoids adapter and step ring provided by Dr. Klaus. NG gear
