Hi,
I am trying to upgrade motorised lenses from 2.8-12mm to 8-32mm.
After having done the mechanical transplant which went well there is OK functionality but there are problems as no autofocus and I dont seem to get the full range of zoom as missing high and low ends.
SO it seems there must be some hard or soft coding for the lenses in the camera. The lens driver boards seem identical so can anyone point me in the right direction?
