Maven CS.2A spotting scope

with No Comments

The CS.2A 26-66×85 is the most powerful optic in Maven’s C-line of spotting scopes and binoculars. It features Chinese ED glass and construction. But before you turn up your nose, know that there is a wide range of quality between various factories and cities in China. This scope looks every bit as well made as Maven’s Japanese built scopes, so much so that I honestly couldn’t tell the difference were it not for the MADE IN CHINA printing at the bottom of the tripod adapter foot.

The main difference between this scope and their more expensive Japanese spotters is that the C-line has ridges on its focus and power wheel, whilst the Japanese S-series spotters have a fine checkering. Otherwise, the C-line has the hallmarks of Maven’s scopes: Dark grey polymer armor on the body and smooth turning focus and power rings.

Optically the scope is sharp, bright, and with good color rendering. At maximum magnification, the image was slightly darkened but exhibited little if no chromatic aberration at long distance.
