I had never tried the instant focus style binos. I am used to having to spin the focus knob to zero in on game. These truly are set and forget. When looking for game, you don't know what range it is going to pop out at. These allow you to quickly cover large areas without having to constantly refocus.
They are limited in how close you can focus, but for safari or hunting, that is not an issue. The speed and ability to quickly bring them to the eye and scan without adjustment far outweighs the lack of close focus and any slight compromise in clarity compared to a set you have to refocus on every object.
Wild animals often got away before I could get my old binos focused. Now I bring the glasses to my eye and I can count horns or tell if a shadow is a tree or an animal before it slips away.
There are probably better set ups for birdwatching or astronomy, but for spotting and scouting these are top notch. Light, clear, and incredibly fast.
Pros: instant focus at practical ranges
Cons: absolute clarity is compromised for speed
