The lens goes to 1:1 without the need for tubes. Because this lens has an extreme version of CRC (close range correction) the front element to subject distance becomes inconveniently short. In effect it's a zoom focus lens, shortening the focal length by approximately 50% at full extension, which is how it manages to get 1:1 without extension tubes.
The Nikkor micro 55mm is a much better lens, I dumped the 60 in favour of a 55, which is an excellent lens and will accept extension tubes or bellows without any issues.
Used as intended, the Nikkor micro 60mm 'D' is a good enough lens. It isn't a good candidate for adaptation or pushing the boundaries, I just discussed this with Birna (Bj¸rn) R¸rslet and that is her view.
The CRC mechanism is complex and fragile, there are two groups of elements which focus at different rates, if the lens has been dropped it's likely that only one group of elements are functioning correctly. It will likely be very expensive to fix it properly.
