Resolution wide-open is 46 lpm and 68 lpm at f/8 - which is excellent
not only in my opinion but compared to their own rating for 135/2.8,
for instance. The one star must be due to the low uniformity across the
frame and to the high light fall-off ( > 1 EV).
I would advise against any overall rating. Just read the details
and judge for yourself.
