Good day.
I've tested Fujinon SF 250mm lens and if anyone is interested.
Conditions:
Lens was fixed at Wisner Technical Field 5x7
At the back of the camera I set Nikon D2Xs (half frame 12mPx DSLR)
In front of Wisner was set mannequin called Frosya :-)
Distance between Frosya and lens was 9 ft.

There are apertures from 5,6 to 22 marked at the lens, but You can close it up to f90, so what I have done )
Now You can see actual pixels crop 300x300 of Frosyas eye at different apertures.
