I am looking at getting a G-claron lens specifically for 1:1 reproductions of flat work, so basically what the lenses were designed for. I have never used one before and was reading the spec sheet for it and came across this graph. If I am reading this right, since the angle of view at f/22 is 64 degrees, then I can expect a one stop loss in the corners, correct? I was looking at the 150mm or 210mm FL, so the image circle would not be significantly larger than the 8x10 film. Can anyone tell me if I am reading this graph right, or what I can expect in terms of practical use from these lenses at close range? I know a lot of you use them for infinity focus, but that does not relate to my needs.
