Certainly not. Field curvature is taken care of in our testing.

Then either you guys or me have a bad sample of one of the lenses? <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='Smile' /> I have specifically refocused for the regions/points of interests and I can see both corners on the frames... I haven't seen any de-centering related problems with either of the lenses. Any ideas about what's causing the differences in the observations then?

Our "corners" are still more extreme here.

That may be so but even the point I have chosen is too far close to the edge of the frame (if you think of the circular border it represents) and people will unlikely put the subject that far out in a real-world composition. It's well outside the width of the frame for most parts and goes up to 97.6% of the frame's height. If you choose a point that is even "more extreme", I'm not sure whether that's a figure that's going to be useful for anyone.



Also readers would find it useful to see what these points are as most websites that choose only specific points show where they are on the frame.

You may notice that the Canon has a better border behavior though.

Then I'm wondering why you said that the [url="http://forum.photozone.de/index.php?/topic/366-next-pz-lens-test-report-nikkor-af-s-24mm-f14-g-ed/page__view__findpost__p__3069"]Canon has non-existing border behaviour[/url], keeping the center-corner differences shown at f/1.4 between the N and C in the graphs aside <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='Big Grin' />
