I have an inkling that my Rodenstock 90mm HR-W is decentered and am wondering how I might go about methodically testing for this? I loathe doing test shots, but this might be one instance I need to suck it up and do some just to put my mind at ease.
Basically I've been shooting some 6x13 ratio, stitched panoramic images with my Credo 60 and the left side of the frame seems to fall off, with the plane of focus having the appearance that the front standard has some slight swing engaged. Of course there is always a small chance that the front standard of my Techno is not exactly parallel, but the problem doesn't seem to exist with my Rodenstock 55mm APO–SD. I'm shooting almost exclusively at f11.
