If I had to come up with a ranking (best to worst):
1. Olympus FT
2. Nikon
3. Canon
4. Olympus MFT
5. Sony
6. Panasonic
7. Tamron
8. Pentax
9. Sigma
10. Samsung
11. Tokina

Thanks for the list... wonder how they rank when zooms and primes quantities are separated. But then again, FT and MFT are mostly zooms so they must do a good QC job.

Prime lenses are, of course, better centered than zooms. We've rarely seen issues with primes actually.
The biggest problem makers are ultra-wide zoom lenses (usually issues at the image sides) and high ratio zoom lenses (center centering -> contrast).

Yes, I agree about the complexity. Also the UWA lenses need only a little error for more things to go wrong when compared to tele lenses.
