Conclusion: It is a well-made product of that widely-known American company. Especially impressive is the build quality. The device got the maximum score for the housing which means that none of the critics from our testing team found any reason to deduct even half a point - it happens really seldom.
Pros: very solid housing,, negligible distortion,, slight coma and astigmatism,, excellent whiteness rendition,, negligible flares,, good blackening and workmanship inside,, sharp image already from 1.7 meters.
Cons: minimally truncated left pupil,, the transmission level could have been higher.
