Hi,
I have been mounting several old Nikkor lenses on my Pentax K20D, with nice results, most notably the 28mm AiS and the compensating 55mm f/3.5 micro.
I had an older Nikkor-Q 200, with oily blades which I wanted to try on the Pentax as well. Following instructions here and at the Yahoo Nikon group, I was able disassemble the entire lens, clean and grease he helicoids without breaking anything.
All neat and well, except, when I tried to reassemble the inner lens element - the chunky one which sits atop a ring on the other side of the diaphragm, I ran into trouble.
The element seems to be seated correctly - but when I screw the retention ring that goes over it - the ring screws in smoothly and nicely but stops about an 1/4 of an inch afar from the element, leaving a gap so there's obviously something quite wrong - but I have no clue what is missing.
I do not recall there being a gasket, or any kind of rubber ring, or anything either below or above the element...
Is anyone experienced with this lens? Or at least, can anyone point to a digram of it - I know there's a book by Tomosy, but it costs more than what I paid for the lens. Of course, I will buy it, if its the only solution.
Any help will be greatly appreciated!
