My 2 cents, cell cameras ARE too much technology. I personally know people that have changed hunting plans and harvest animals because they saw them on camera. As in, "I know we were going to have a deer drive on such and such property but I just saw a dandy 10-point behind the house so I'm hunting that ridge tonight." Not illegal but just leaves a bad taste in my mouth.
Like many others, I don't feel as strongly about IS optics but they aren't for me. Want to know how much I limit myself? Most of my optics are Vortex! As some of you point out, I'm not that far removed from hunting with a spear from a cave.
