(1) Such as...?

(2) I can agree with this for sure. The thing is, I suspect that the Lenstip result is due to one of two things (or both)

- sample variation

- their test method does not take into account, that the lens is designed to give maximum effect for portraits /out of focus, 3 D effect. The specific output may not be everyone's cup of tea.

So, the progressive corner border and corner sharrness test, as per charts looks so bad on the chart, MAY actually be due to the design.

Now, if this is so, why do some lenses with excellent 3D ness and bokeh etc, fare better in the border/ corner sharpness test?

Such as the Zeiss Otus :

Real world by 'whomever' (amateurs or pros irrelevant).

The Zeiss clearly shows excellent real world use, 3 Dness, etc, and still cleans up on the Lenstip Test.

BUT, we can see that the Zeiss at maximum aperture, also shows 'test weakness' in the borders on full frame. Again, may confirm that testing such lenses AT THE 1.4 aperture, is missing the point, if we accept that this is design specific. But the result is clearly much better than the Nikon AT ALL apertures.

Which is why I again wonder about sample variation with the Nikon (as surely we might expect that on stopping down the Nikon would would improve).

But, some may say that comparing a USD 1,800 lens to a USD 4,000 lens is unfair.

But, it is just a comparison,  and in reality, there is nothing wrong with analysing, indeed analysis is what makes us understand more.

Cheers.
