Harpers Photographic

With the Bresser Montana range nothing has been spared that might compromise the performance of these binoculars. The finest materials combined with cutting edge design and construction ensures a brilliant performance. Phase coated optics insure maximum light transmission. All internal prisms use Bak-4 glass material that gives accurate colour rendition and stunning image quality. Maximum user comfort has been engineered into these superb binoculars.

All Montana models are water proof and filled with nitrogen gas to prevent internal fogging. They come with twist up eyecups, individually adjustable, which provide a 100% field of view for use with or without spectacles. They are supplied complete with leather case, straps and lens cleaning cloth.
