RE: Do you prefer an adjustable objective or not?
Only way to go if you ask me, even for your hunting rifles. I suggest keeping them on a lower power most of the time so you can see what you are shooting at close rnge if you jump a deer, or something else. Odds are, if you are at distance, and need to see something up closer, you will have the time to power up a higher magnification to see, and that the animal in question has not yet seen you either. Makes some shots safer in the sense that it will also allow you to know what you are shooting at in the lower light and the deer 2-3 or more feet in the edge of the woods.
