Oheremicus,
A scope with an Adjustable Objective has a shorter depth of focus than one w/o. A scope with the Side Focus/Parallax adjustment feature has even less.
You've posted this often. New shooters should not be influenced by your fettish against AO and SF. And as often as you do and I see it I post the same thing in opposition. I have both AO and SF scopes. I set them for about 150 yards and have never had to fiddle with them. If I find something with the binoculars so far away I need to adjust them I have lots of time to do so. The animals are not aware or at least not wary of me.
