    I just mounted a Nikkor 480mm f8 APO lens to a Cambo lensboard. The retaining ring is now (semi) permanently attached to the lensboard so I was wondering if the other Nikkor APO process lenses used the same retaining ring. If that is the case I will be on the hunt for more of these lenses in various focal lengths.

    It should use a flange instead of a retaining ring. The flange should have holes drilled into it for mounting to a lens board using screws.

    Ya ya, so I used the wrong name. It's the flange I am talking about. What do you know about them??

    According to a PDF of some old literature I found on the web, the 420mm f/9, 455mm f/9, and 480mm f/9 all use the same 90mm x 1mm flange. I'm not sure about the printing date, it might be 1982, and I've no personal familiarity with these lenses so can't say if they varied over the years. Here's the complete list:

    180mm f/9 53 x 0.75
    240mm f/9 53 x 0.75
    305mm f/9 72 x 1
    360mm f/9 72 x 1
    420mm f/9 90 x 1
    455mm f/9 90 x 1
    480mm f/9 90 x 1
    610mm f/9 110 x 1
    760mm f/11 110 x 1
    890mm f/11 162 x 1.5
    1210mm f/12.5 162 x 1.5
    1780mm f/14 213 x 1.5

    Don't drop that 1780mm on your toe, it's listed at 6.43 kg, a bit over 13 pounds.

    Sorry, Eric. :smile: I knew your Nikkor process lens used a flange and figured you never had a lens with a flange before and liked it better than a retaining ring.

    I have never handled any of the Nikkor process lenses but in all the photos I have seen the flanges looked to be the same design.
