I've just purchased an 890mm Apo Nikkor f11 for a song that I want to experiment with LARGE paper negatives etc. I realise that these process lenses were designed and corrected for 1:1 work, and I've read the scores of arguments about whether they are sharp at infinity. I also discovered an entertaining read in regards to the 'flat field myth', where the discussion about flat and curved field designs really make a difference. It seems that many people are using the Apos in the field with success.

Can anyone tell me what the projected image size for one of these would be at 1:1 and infinity...I'm hoping to get larger than 24" square? Has anyone got any first-hand experience with one that they might share?
