Is there any chance you can shoot a grid at the major focal lengths you listed below and post samples or see if you can get it to true rectlinear by the lens correction adjustment slider in ACR / Lightroom? I would typically shoot mid to long distance with mid aperture (f16 in this case maybe?)
I compared the MTF between this zoom and the equivalent primes but a chart is not as good as a real test.
There aren’t many samples around for some of us to do this test. If you could help I will be very very grateful.

Hi Steve
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.
