I just returned from a 4000km round trip using my van as a camera shooting 24"x32" tintypes. I was using an 890mm Apo Nikkor that has a huge image circle at portrait distances and still covers 20x24 at infinity. I paid $350 for the lens.
You can see some of the plates on my blog if you're keen
I have 3 APO-Nikkor (process) barrel lenses which, according to Nikon product information, have huge image circles (never been close to make use of it!);
APO-Nikkor f:9/360 mm, IC = 600mm
APO-Nikkor f:9/480 mm, IC = 800mm,
APO-Nikkor f:11/760mm, IC = 1170 mm.
I use them together with a Sinar (Copal) behind the lens shutter, for 4"x5" to 8"x10" film format.
I didn't pay a fortune for these lenses some years ago on eBay.
Bertil, you are much too trusting and and aren't thoughtful enough. Apo-Nikkors are narrow angle process lenses. Shorter ones (150 mm - 240 mm) just cover their focal lengths at infinity. Longer ones have less coverage.
The coverage figures you posted are for 1:1, are twice the lenses' coverage at infinity. See this: http://www.galerie-photo.com/apo-pro...ikkors-en.html .
