Zoom binoculars are one of the rarest types of binoculars on the market. They are versatile and very affordable, providing an optical compromise with multiple magnification levels in just one pair. Magnification therefore isn’t fixed and can be adjusted with zoom-in and zoom-out system. When tracking the following object, you can easily change from low to high power in the matter of seconds, to get finer details and improve your visual experience. Zoom binoculars are mostly suitable for long range observations such as marine applications and astronomy. They also come in handy when hunting, but are providing smaller field of view and are therefore less suited for bird watching and other dynamic applications. The quality of zoom binoculars is not as good as in high-ends. The mechanism of zoom binoculars is a little bit complicated and is equipped with flexible linkage bend that helps to maintain clear images of moving lenses when adjusting the focus whilst zooming. The perfect synchronization is thus harder to maintain due to many zoom mechanism parts, making images fuzzier than by the conventional ones with fixed magnification. Due to this moving mechanism, lenses are hard to perfectly align, also providing collimation issues.
