I‘m now on my second copy of this lens. Maybe I‘m expecting miracles (especially for the price). Despite being impressively sharp at 12mm and F2.8 the performance throughout the focal range is not consistent. From 20mm to 24mm at F2.8 a quarter of the right hand side of the image is not sharp. Stopping down to F5.6 improves things a bit but still not as sharp as the rest of the image at F2.8. If it were only the corners and extreme edges I could live with a some lack of sharpness wide open.
Field curvature would surely show on both sides so looks like the lens is another decentered copy.
The plan was to get this lens and ditch the 16-35mm GM, Sony 12-24mm G (sadly already sold) and a couple of other lenses.
Now I‘m not sure what to do....Try yet another copy or just simply give up and stick with what I have but now without 12-15mm covered?
The reported number of substantially decentered GMs at this early stage is a little worrying. I just hope this doesn't turn out to be one of those lenses for which it's really hard to get a reasonably well centered copy. The other two wide GM zooms don't have a good reputation in this regard.
It took me multiple tries to get a copy of the Sigma that's good across the whole range, but other FM members have managed it on their first try (Fred received two in a row). I certainly won't be letting go of mine until I know I can get a Sony that's at least comparable. Not much point spending considerably more money for a poorer performing lens...
