tested it with the Z6, the central area is super sharp at 1:3.5 and the corners clean up progressively to 1:11. Like my 3.5cm 1:3.5 it holds very nicely at 24mp all the way to 1:22.
The front element is ridiculously small. So the first test was with a regular width B+W filter, but it cut deep into the picture area, replaced it with a slim filter, and that one cut in only at 1:22 - have a super slim one on order.
If interested go look at the series in Flickr at 100%, uploaded 3.5, 11, and 22 only, the other apertures only change the corners and the amount of vignetting.
MIND you - the corners can be decent at any aperture, it is curvature of field that makes them fuzzy, selective focusing for depth of field can greatly enhance the corner one is interested on.
at 1:3.5: very decent central area, heavy vignetting
