Wide field of view, great visibility in any conditions.
Porro prism. Magnification: 7x. Objective lens diameter: 50mm.
Levenhuk Sherman PLUS 7x50 Binoculars are ideal for all types of field observations. Powerful objective lenses gather more light and produce bright, sharp views even in dim light conditions. The fully multi-coated optics are made of BaK-4 borosilicate glass. The rugged shell is coated with soft rubber. This model is completely waterproof.
The Levenhuk Sherman design uses Porro prisms that offer a wide field of view. All optical surfaces of four-element eyepieces and two-element objectives are fully multi-coated. Long eye relief makes these binoculars a perfect tool for people who wear glasses. The eyepieces feature convenient twist-up eyecups. These binoculars offer a diopter adjustment to compensate for the difference in strength between your eyes.
