Following on from the success of the Swallow 65mm and 80mm ED models, we introduce the compact Swallow ED 50mm From the extra-low dispersion (ED) glass objective elements to the dielectric coatings on the prisms, these telescopes perform to a level not seen in instruments at this price point before. A lightweight, yet robust, polycarbonate body material Following on from the success of the Swallow 65mm and 80mm ED models, we introduce the compact Swallow ED 50mm From the extra-low dispersion (ED) glass objective elements to the dielectric coatings on the prisms, these telescopes perform to a level not seen in instruments at this price point before. A lightweight, yet robust, polycarbonate body material, means that the 50mm weighs in at just 900g The features don’t end there – dual focus wheels with different gearing enable a much finer control over focus accuracy at high magnifications where depth of field becomes very shallow. It is waterproof, come with stay on cases for added protection, and is backed by a 10-year guarantee. Take your wildlife viewing to the next level
