Hi Ken,

I'm back again. Today I saw the Multigrade head. And there was a problem. The item where you have to give some input to let work the automatic scharpness don't work. Only the button for the scharpness of the objective is working.
Is the possibility of the automatic scharpness really necessary?
What if the whole bloc is no more working? To throw away the whole head?
Or is it possible to let repair the inside of the electronica?

You see, it is a very difficult decission.
