Hi again Ian. I'm not sure that I understand your last post? Regarding the coverage of the lens, I just checked and this is what I found. Focused at infinity and at f/9, the lens just covers the ground glass. I played with the rise and shift to see the darkening of the corners and it looks like it just covers. Of course, the corners of the ground glass on my century universal are cut so there may be some darkening at the far corners that I can not see. I'm not sure how these RR lenses respond to closing down as far as image circle is concerned? If the image circle increases at all when stopped down then it will certainly cover the format. As I mentioned, no wiggle room at all. Accordingly, I would consider it a useable lens on 8x10. Would appreciate your thoughts on this...
