I do not have the facilities for this type of test but I have taken many outside Building shots where verticals need correcting using my CS5 software and these are good but not perfect (every radial distortion correction results in a fault elsewhere however slight it might be)…I have never used Lightroom and its built in Lens correction adjustment..
However, I would not recommend this Lens for exacting interiors as is your need, there are obvious drawbacks to Zooms. I found the edges softer than the 30mm Prime and ‘Barrel’ was obvious the closer you were to the subject on top of focal length.
I am sorry not to be of any help to you and would suggest maybe a wide PC Lens on Nikon or for Medium format… Hasselblad offer a tilt/shift adapter for their own HS Lens ranges, great for converging verticals albeit time consuming.
You can use the Hasselblad TS adaptor on the S…
