For most folks, the 4.5x native magnification is going to be a bit much for typical hunting. On the properties I hunt, I have feeders at 45, 85, 100, 110, and 120 yards. It is great at 45 yards if you are hunting mice, or if you want to shoot the left eye of coons. At 85 yards, it is tough to track moving animals. It has a very narrow field of view.
However, if you are a 100 - 300 yard hunter, I think it will be an excellent scope.
For general purposes, the Zeus 3 would be better in terms of magnification. However, you can get the MKII or MKIII in 2.5x and have a better general purpose scope than the 4.5x version.
I like both scopes, but they are very different.
What do you plan on hunting, how far, in what sort of environment most of the time?
