Even so, that seems to be a good indication with the test done.
Casing point that there is no "ultimate" all round scope.
Indeed so; and the ZO is (imo) in some ways a rather under-rated scope given that it also outdoes a Bushnell Trophy and a Hawke Reflex 3-9x40s in the same low light conditions, which suggests the 4200's comparative performance although inferior to the ZO wasn't at all bad.
