This review is for the non-D version of this lens which I understand is exactly the same optically and mechanically (except the aperture lock which was improved in the D version and easily snapped off in the non-D).
I used it over a period of ten years and it took considerable battering and survived without a mechanical glitch. The distance markings run off after a while which is annoying and reduces the resale value of the lens (I suppose one could try and treat it with more respect than I did).
It seems heavy by todays standards but that's comparing with lenses that just aren't as tough. It's very well balanced with bodies like the F90/N90 or heavier F4/F5.
The optical quality is truely excellent; sharp to the frame edges and very good even at f/2.8. I sometimes wished for the zoom range to go down to 28mm but you can't have everything. In fact I would suggest that, unless your photography doesn't give you time to change lenses, you're better of with this lens and a separate 28mm prime (the Nikkor 28mm f/2.8 AIS is stunning)
In the end it suffered from a fungus attack. I think this came about since the push pull design of the lens sucks in a lot of air and in my case probably fungus spores on a trip to humid Cambodia! Nikon couldn't clean the elements and I had to sell it off as a soft focus lens (yuk!)
