Those recommendations are a few years old, so I need to update them. A lot of new scopes came out since then.
Still, the ZA scopes are pretty good and compete reasonably well against other similarly priced scopes like the Conquest HD5, Meopta MeoPro, Leupold VX3 and others.
Current ZA5 line is upgraded compared to the original ZA5s that I looked at and they are nice designs.
Generally, of the currently available hunting scopes in the $800 range, I am really partial to Vortex Razor HD LH, but they all come with 42mm or smaller objectives, so if you want something larger than that, look elsewhere and Minox is not a bad place to do so, as is Meopta.
