Very interesting. It would also be nice to see the difference with a software perspective corrected file and one made with the shift of the optics.
It would be nice to see what happens with the 12mm Samyang ( which does have an aperture ring).
Another consideration that I make by watching this image is that when you have line perfectly perpendicular, they appear to be overcorrected ( it is an optical illusion) and that leaving 1º tilt uncorrected makes them look generally more natural.
I don’t know if you are familiar with this but some people talk about it here for example.
Note > There is a limit to the amount of correction that can be undertaken in some images before shapes at the edges appear excessively distorted. In some images where the verticals of a building are fully corrected, so that they run parallel to the edges of the frame, there is an optical illusion where the building appears to be growing wider. In these instances Upright may adjust the converging verticals so that they are not absolutely vertical.
the popular expression wishful thinking is an oxymoron!
