I have no issues with the normal vignetting the lens seems to have, but the mechanical vignette 1) seems to vary copy to copy, 2) is inconsistent in nature as to when it appears, and 3) TTA proved that they can improve/eliminate it (the whole Z 75 saga).
There are other lenses of similar FL and speed that don't exhibit the issue, so I don't personally accept that it just is what it is. As it stands, it feels like buyers of this lens are playing a copy lottery which I detest.
my copy doesn't seem to have this mechanical vignetting issue, i wonder if it is inconsistent manufacturing of the rear baffle that leads this variation.
That is my current hypothesis and what I pointed TTA to weeks ago.
