Yes, it is common.  Most 3.5s will vignette at f16 too.  There is some
variation, the source of which I have not been able to pin down.  Ilex
lenses strike me as more prone to vignetting than regular 3.5s.

>The Realists f/2.8's don't do that...

That's correct.  I do not see vignetting with my 2.8 at 7p.
