Summary
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.
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. In other categories connected with workmanship like blackening, focusing, coatings, prisms’ quality, IPD or tripod the Bushnell Legend also reached results close to perfect.
If the optical categories’ scores, are added to that performance, and they are in the range from medium to very good without any serious slip-up, we must reach a conclusion that this instrument can be recommended to anybody without reservations.
