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
This needs to be correlated to the service quality - locally it's roughly:
1. Olympus
2. Nikon
3. Pentax
4. Canon
5. Sigma
6. Tamron
7. Panasonic
8. Sony
9. Tokina
10. Samsung
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).

That's really not good..! I have the Tokina 11-16mm down as my next lens... maybe that should be 'had' now...? <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/sad.gif' class='bbc_emoticon' alt='' />
Is there a quick and easy test to check for this issue?
