I was looking at the ImaTest Explanation link so I couldn't find the regions of interest but now found them in the Len Test FAQ. Thanks.

Just to mention - there's, of course, still some resolution - we defined a 3px blur as "poor".

I'm just wondering how you explain the differences between off-center resolution figures that you calculated and the ones I observed. Because we have made opposite observations and I have shown my results.

If you take a 2-3px image it'll still print great on 10x15cm.

I can confirm that a 2MP image shows the off-center problems, especially with point light sources... for example in 1080P video. But, as I have been saying, both lenses are close in this regard.
