How much more generous is the image circle and coverage of the Rodenstock Sironar W 210 lens vs an older single coated Fujinon W 210 (mine is in a Seiko shutter) with the writing inside the the inner ring of the front element? The older SC Fujinons have a reputation for having a more generous image circle than their later MC brethren. This would be used as a wide angle on 8x10. I will mostly be contact printing, though it is conceivable I could enlarge 8x10 if I ever get to setting up my Zone VI enlarger. One big advantage for the Fujinon is that I already have it. Thanks. Sincerely, Hany.
