The elegant Topas line consists of proven porro-prism construction binoculars with fully coated optics. The powerful, variable, magnification allows the Topas 8-24x50 zoom binoculars to be used for a wide range of applications. The magnification can be easily adjusted during use by a simple lever. Of course, these practical binoculars also have dioptre compensation and the eyecups can be folded down - making them ideally suited for spectacle wearers. The partial rubber armouring ensures a secure grip and centre-focusing ensures that they are simple to operate. A practical thread for using a tripod adapter is built-in to minimize fatigue during prolonged use and to provide a steady image at higher magnifications.
