Interesting they say it's quite a bit worse than the Batis 18 at f/4 and f/5.6. There must be some sample variation at work, as from memory, more than one forum member has found the 12-24 to be better than the Batis 18 at the edges.
Batis 18 f/5.6: 5199, 5097, 4191, 3965
12-24 18 f/5.6: 4854, 4362, 3927, 3698
24-70 24 f/5.6: 4985, 4508, 3913, 3753
So the 12-24 at 18 is close to the 24-70 GM at 24, but it seems they're still not quite prime quality.
I've been following Photozone's reviews for long time and really like Klaus' tests. It's a way to know how a lens performs at close and mid distances. However...I keep a couple things in mind...
How close does he need to be to a test chart with an ultra wide? That's probably makes for the discrepancy compared to infinity tests.
I've tested many copies of the FE 12-24G and only one was really great from 20-24mm, so there is variation in play. I believe he only tests one copy and therefore we should treat his results based on one sample. IMO, it's a good ballpark as long as it's not a terrible copy but it's never enough to definitively conclude on how the lens performs.
