I think we all have different degrees of tolerance to imperfections. Personally I don't view decentering to be as one of the worst, providing it is not excessive. Of course I still want the best possible, but there is a "good enough" point where I worry about other things.
Actually, there may be one "good" FE lens, the 35mm f/2.8. Lensrentals.com tested them on the A7R and suggest wide open, it'll beat stopped down primes on a D800e at MTF numbers, with usual disclaimers about comparing across systems... no OSS to get in the way there
Back to the Kurt's review, just to check my reading of it. His complaint appears to be of soft borders at wide angles. If I look at the MTF chart, that shows a dive at the extremes. Is that not consistent with the images? So my interpretation of this is that it is not a QC problem but the actual design was never going to give you decent borders in the first place.
