The device works flawlessly at first there was nothing to complain about. But then after half a year nem grinds the lenses when focusing (ohen any case stuzr or other pressures which hurt to wear) grinding and for a time manual jammed turn. Since the unit still has warranty sent to Nikon which is then told me the warranty shall not be liable and I would have to pay 80% of the original price of the lens for repair. After some mails with the competent staff at Nikon I resigned myself and just paid it ... Then, the product came back and I had to realize, however, the terminals was resolved not to cut. And that is not at all that needed to be resolved and it did not resolve what a fall to something another?
I advise everyone not to purchase Nikon products ... so far had only problems with this ******* Laden ....
