I like the idea of having a FOV which is much higher than 30-34ft@100yds, and I also like the idea of being able to bring in the target better than a 9 or 10 which I now have.
I also know that getting the big zoom has it's compromisies, such has holding steady while hunting. The 2-12 range just seems to have the abilities of a great short range FOV, and a very decent high end, for those who don't hunt at a 1000 yds, which is 99,9% of us.
