The name says it all! The Bresser Special-Zoomar 7-35x50 Binoculars offer fascinating sharp images. The individual eyepieces are carefully tuned to each other, making the magnification variable through the use of the zoom lever. Thanks to the FMC coated BaK-4 glass material objects at great distance can still be seen as clear images. The handy and ergonomic rubber covering provides for a stable hold. The standard tripod thread and adapter provided, make it simple to attach these binoculars to any photo-tripod.
