    Re: Rodenstock Grandagon N f6.8 75mn

    How about if that 24 is a typo and should read 42 .. that figure 24 is difficult to explain with 42 and 38 just next to it

    Bob,

    thx for info !!
  5. Re: 760mm Apo Nikkor f/11 vs Nikkor-T ED 800mm f/12

    Interesting.. I was thinking more of lenses for aerial reconnaissance .. not the newer ones .. certainly optimized at infinity .. but at focal lengths over 300mm real beasts ..
  6. Re: 760mm Apo Nikkor f/11 vs Nikkor-T ED 800mm f/12

    Yes .. Perkin Elmer and others .. but often no iris, extreme weight .. a challenge to adapt .. and were they so much better ?
  7. Re: 760mm Apo Nikkor f/11 vs Nikkor-T ED 800mm f/12

    No problem with the 110mm flange on a Sinar board .. fits nicely .. great combo with Sinar/Copal shutter .. light weight and performance !!
