Lately I have been swapping between 2 scopes A Burris 4.5-14x32 (burris replacement for their short mag series) and a Bushnell 2-7x32 . depending on type of terrain, (Typical new England Mixed hardwood and firs , with an occasional High open field, or farmstead .
The 2-7 magnification has been a non-issue for the varrying terrain I hunt. I have found myself using the 4.5-14x32 a bit more but it's less about needing more magnification and more about personal preference. I usually keep it set at 4.5 in woods and only occasionally need to bump it up just a tad when I approach an open area.
I have also been satisfied with the light transmission capabilities of each scope using the smaller objective lens, even as dusk approaches. The smaller objective has been a non-issue, and I like the fact it mounts low on my rig.
I believe the Burris adjustments for 2-7x35 are 1/4
