Does anyone happen to know the size of the image circle (IC) of the Schneider 120mm Macro Apo-Digitar when used at infinity (say, at f11)? From the specs on the web it appears that the IC size progressively decreases:
At 4:1 [4x Life Size] - 110mm @ f5.6
At 2:1 [2x Life Size] - 110mm @ f5.6
At 1:1 [Life Size] - 110mm @ f5.6
At 1:2 [1/2 Life Size] - 90mm @ f11
At 1:4 [1/4 Life Size] - 80mm @ f11
Cheers,
Angus
