    Nikon Nikkor Apo-Nikkor F:9 - 240 mm

    Hello !
    I've got this lens near free. In it's wooden bow with a set of parts that puzzle me.
    There is a picture of it here : http://en.wikipedia.org/wiki/File:ApoNIKKOR240.jpg
    As you can see there is a silver colored lever on a ring above the stops markings.
    This lever opens a gate in the lens barrel and on this gate one can put something looking like filter holder (for Kodak gelatin filters I think) and/or one of what seems to be a F-stop of very small value (the hole in it is less than a millimeter diameter).
    I wonder what use one can put to these contraptions ? and what effect they may have on the lens's performance ?
    Also, I would be glad to get more information on Nikon process lenses if available ....
    Many thanks in advance for your help !

    The lens was designed for photoengraving. It will take filters and Waterhouse stops, which would be the one with the hole. These stops were made with different shaped holes for use in making half-tones, and the filters for color separations.

    The lens will work well in the field stopped down. You need not worry about stops and filters, just keep the slot closed to prevent dust entering.

    I have the 450mm version of this lens; super sharp and good contrast.

    I have the 240mm f/9 Apo Nikkor, don't know which version. My sample is very/extremely sharp down to about f/16 then it starts fuzzing out the more you stop down to the point that it is useless at f/64. I still use it on occasion.
