Zeiss 4x12 T* Monocular

ZEISS Monoculars are the ultimate blend of versatility and portability, making them an essential companion for sporting events, theater performances, and outdoor adventures. Designed to fit effortlessly into a jacket pocket, handbag, backpack, or glove compartment, these compact optics offer outstanding convenience without compromising performance. Whether observing dragonflies in the reeds, birds at a distance, or fine details up close, ZEISS Monoculars deliver sharp, high-contrast images thanks to the T* anti-reflective coating. Certain models even amplify ZEISS binoculars by tripling their magnification, effectively transforming them into a spotting scope. With models ranging from the ultra-compact MiniQuick 5x10 T* to the powerful Mono 10x25 T*, there’s a perfect option for every need. Lightweight, durable, and engineered for exceptional clarity, ZEISS Monoculars are an invaluable tool for nature enthusiasts, travelers, and sports fans alike.

Always at hand

Small, light and sporty - the compact Monos are always handy for nature excursions, concerts or sporting events. They bring objects to arm's length at lightning speed so you can see every single detail. A diopter adjustment is possible to up to +/- 4 diopters.

ZEISS T* Coating

ZEISS T* coating is a guarantee of the brilliant, high-contrast images­­ which you will experience above all in adverse light conditions and in the twilight. Behind it, however, there is no specific formula for building up the layers. Instead, it is a technology that is constantly adjusted to suit new glass materials and requirements, which varies from lens to lens.

Triple amplification

The Mono 3x12 T* can transform your Victory FL and Conquest binoculars into a high-performance spotting scope in the blink of an eye by tripling the magnification. A practical alternative to a spotting scope, which pays off on long and varied excursions, such as birdwatching or insect hunting. The device can be securely fixed onto the eyepiece by means of an adaptor ring, opening up a hugely detailed visual experience. The Mono 3x12 T* can also be used on its own as a miniature telescope or as a magnifying glass at close range. The Mono booster is so small that you can easily take it with you wherever you go.

Close range

The Mono models 4x12 T* and 6x18 T* with their close focus capabilities are suitable for use as a magnifying glass or visual aid. This makes them extremely versatile. Whether you are watching butterflies, reading a street plan or walking map, or making out letters and numbers on a bus timetable, the Monos are a practical tool.
