Yes, this confirms my impression that some owners are happy with their lens. So I live in hope that something can be done with mine.

Perhaps it is difficult to determine which part of the image circle is used when the lens is shifted (the tilt just alters the location of the plane of shark focus), but on the other hand, image circle is image circle, certainly nothing of this is contained in the exif data of any lens, so, I may be wrong, but I can't see why it should be impossible to work out a profile. Difficult, yes, but DxO is anyway pretty selective with their profiles - Samyang, for instance, is apparently below their dignity. Again, my hunch is that they thin PC-lenses are just not worth the effort.
My problem is: their selection pushes consumers in a certain direction. And I become wary when I start suspecting that my style of photography is about to be influenced by industrial products.
