Great lens, not just for the price. Sharp into the corners on a 45 mp Nikon Z7, and small/lightweight.
It's pretty good in the corners and definitely usable, but not exactly what I would call sharp in the corners like it is in the center or even midframe. We just measured it in the lab at PL and the drop in the corners is pretty substantial, which can also be seen just taking controlled shots.... for typical landscapes it still looks great of course but you can definitely see it.

I did read Spencer's remarks regarding the shooting distance.
'We use the largest test chart available from Imatest, and in my experience, the results describe infinity performance more accurately than close-focus performance. In real-world terms, it’s a good match for shooting a distant overlook with no foreground objects. We refocus at each aperture, but not for each portion of the frame – our numbers all come from what’s possible to achieve in a single photo.'
Isn't infinity the biggest stress test for a lens when the rear lens element is the closest to the sensor?
I did some interior shots, where the lens corners where not bad. But I just look at them at 100% or 200%, nothing scientific.
Thanks for your review. I used PL reviews for many ofy lens purchases.
