Here is a thought that has always messed with my sensibilities….

If you have a lens with a very limited amount of movement, like my 65mm Grandagon, 170mm IC, 10mm of rise / fall / shift, would it not be better to apply rear tilt / swing rather than front tilt / swing since when you do the former, you are tilting or swinging the projected "Cone" of image circle all around rather than the back movements being adjustments to the plane of focus only?

I just want to know if I am correct in my thinking that you would less likely run out of image circle if you make tilts and swings using the rear standard…is this right?
