A good lens but not quite as desirable as the 45mm f/1.2 PRO

I have the 1.2/45, the 1.2/25 and the 1.2/17 PRO.

Does the tilted focus plane of the tested sample have a big impact on the resolution figures?

I wonder if the tested sample was sub par. The tested sample on imaging-resource https://www.imaging-resource.com/lenses/...ed/review/
was extremly sharp, even in the outer field at F2 ....

With my sample of the 1.2/17 I didn't find any reason to complain about the sharpness in the outer field or even near the edges, of course it's my subjective impression, no quantifiable resolution figures but still....

I had three samples of the 1.2/25 and kept the third one, there was a lot sample variation, rather disappointing sharpness in the outer field with two samples, but the third one is fine, even at F1.2
