conrad_hoffman Posted January 16, 2020 Share Posted January 16, 2020 Wow, no interest at all in taking one of those apart! Link to comment Share on other sites More sharing options...
ShunCheung Posted January 16, 2020 Share Posted January 16, 2020 A couple of months ago, Nikon USA had discounts on that lens and I got one. It is an excellent lens and many believe it is the best 24-70mm/f2.8 out there. It is considerably smaller than the F-mount, AF-S VR version, which is also a fine lens. As a kid (many years ago), I had taken plenty of things apart, but that was easy. Putting them back together was a totally different matter. :cool: 1 Link to comment Share on other sites More sharing options...

richard_driscoll Posted January 16, 2020 Share Posted January 16, 2020 Recently I found the service instructions for the Nikon 16-85 VR DX. I was surprised by the construction with bits and pieces hanging off the barrel along its length and even a fair bit of double sided tape. That 24-70 disassembled above looks more like I understand Canon have been doing it for some time with just one PCB and flexprint running out to the various electro-mechanical sub-assemblies. The 16-85 also uses metal brushes on the zoom encoder; not optical. You can tell it's an old design; part of the adjustment procedure uses a D200! It may be that the design reflects the evolutionary approach that Nikon have adopted. Canon EOS had the electric diaphragm and the focus motor from the first and IS pretty early too whereas with Nikon these were added later. http://ss-it.de/data/lens/AF-S%20DX%2016-85mm%20f3,5-5,6D%20G%20VR.pdf Link to comment Share on other sites More sharing options...
Vincent Peri Posted January 17, 2020 Share Posted January 17, 2020 Hmm... what kind of mind does it take to design something like that...? http://bayouline.com/o2.gif Link to comment Share on other sites More sharing options...
