IMO, Billy Dick is right...

Response to Bigger Objective lens the better.

The larger Objective lenses yield the shallower depth of field needed for range finding... when limited to 12X in Hunter Division.

As a sports reporter decades ago, I regularly used a large telephoto lens (120mm objective) to photograph the pitcher on the mound through the chain link fence behind the catcher at home plate. The depth of field was so narrow on such a lens, that when focused on the pitcher, you could see right through the chain link fence without any distortion. In field target, you can sometimes see this phenomenon looking through leaves and branches that otherwise obscure a KZ (when focused on the KZ). One has to be careful, of course. Because while you don't see the leaves or twigs, you don't want to shoot through them.

I also feel the larger objective lenses (and larger diameter tubes) admit more light, useful in those darker lanes. Some will dispute this, so I guess it depends on the scope. In my experience, a 50mm objective (generally) gathers more light than a 32mm objective.

The new Optisan "EVX" line, 6-24×56mm looks interesting because of its still larger, 56mm Objective. Hopefully it has a 12X marking(?) Too bad they've moved away from the SCB2 "Christmas Tree" reticle, however. The MH10 Reticle does not seem as versatile, IMO. But I have not seen this reticle in person, yet.
