Since Rodenstock puts the IC indicator in the lens, i.e. at the edge of the IC, doesn't that preclude using the lens past the IC? i.e in the case of the 32 and 40mm HR-W the IC being 90mm. Once you it the edge of the IC, you hit the hard vignette of the indicator which ruins anything beyond that point, in fact it can do some damage before by the creating of a white band in front of the dark. Only effect's solid shots, blue sky, dark wall etc. But the C1 LCC will not remove it. It is seemingly more pronounced on the 70mm IC lenses, 28HR etc. Where as Schneider, with no IC indicator allows the photographer go past the edge of the IC, and make the decision on image quality themselves. Thus the reason the 60XL can go to much bigger shifting, it's not just the larger IC of the lens.
When I owned my 28HR, it could easily have made 10mm of shift in many instanced, but by past 5mm, the upper and lower corners were ruined by the dark vignette of the IC indicator. I guess you can go beyond the limit of the indicator i.e 90mm on a 32mm or 40mm if you are willing to crop massively into your shot, but then you may as well used the 60XL?
The 40 HR-W could easily make 20mm with very little image quality fall off, which is well beyond the 90mm IC, but you hit the wall so to speak at 16mm on a full frame back, wall being the IC indicator. The cropped sensor backs can get maybe 18 before you hit it.
If you add rise to the this, then the IC indicator really kills the shot, example a 40 HR-W shifted to 15mm with say 10mm of rise. The entire upper left corner on the 15mm L or R shift with rise is pretty much ruined by a massive amount of black due to the IC indicator. In my test, this was all sky, net, it really didn't matter how good the image quality was, it's sky. But the black vignette just kills the shot and makes 9 part movements with the 40 HR-W pretty much worthless, even 5mm of rise shows this.
Just basing this on my experience with these lenses on IQ160, IQ150 and IQ260.
Net Rodenstock may claim you can go beyond the 90mm of the IC, but the fact that you hit such a hard wall pretty much makes such movement a moot point to me.
I have attached an example from C1, 8mm rise, 15mm L shift IQ260. You can clearly see the effect of the IC indicator, and if you look closely you can also see the destruction the indicator has on the part of the file right before the hard edge of the indicator.
