The Maven CS.2A 26-66x85 has the highest magnification and largest objective diameter among Mavens spotting scopes. The scope appears to be made or at least assembled in China unlike the Japanese S-series scopes. But don't let Sino-Snobbery bias you, the glass and build quality is a match to Maven's other premium optics. This scope uses ED glass like Mavens other C-series scopes. Color balance, sharpness, and brightness were on par with other quality scopes in the 1K-1.5K price tier.
Its only disappointment is it's lack of field-grade lens caps or backpack ready carrying case or skin. While many premium scope brands also eschew accessories, Maven took the time to produce a custom branded front lens cap; yet somehow didn't design it to have a simple lanyard loop to help keep an outdoorsman from losing it in the field.
Despite this nitpick, the CS.2A's body design is armored and ruggedized for harsher outdoor conditions. At 60oz, the CS.2A is impressively light for an 85mm spotter. This scope has the power, features, and style that a well heeled back-country hunters or birders can appreciate.
