Zeiss Mono 10x25 T*

• 10x magnification in a pocket format: The compact body is easy to carry all day, while the higher magnification helps with detailed identification of distant wildlife, landmarks, or action on the field.
• ZEISS T* fully multicoated optics: The lens coating is tuned for strong contrast and good image brightness, which helps preserve detail in difficult light and makes brief observations more informative.
• Roof prism design: The Schmidt/Pechan roof prism layout keeps the monocular slim and easy to handle, so it slips into a jacket pocket and comes into use quickly when a full-size optic would stay at home.
• Diopter adjustment of +/-4 dpt: A wide adjustment range helps users fine-tune the image to their eyesight, improving sharpness and reducing eye strain during longer viewing sessions.
• Nitrogen-filled, waterproof and fogproof construction: The sealed housing is better suited to changing weather and temperature shifts, so the monocular remains dependable for outdoor use rather than fair-weather only.

About the Zeiss Monoculars Series

The ZEISS Monoculars series is built around the idea that useful magnification should be available in a format small enough to carry every day. The range includes 3x12 T*, 4x12 T*, 6x18 T*, 8x20 T* and 10x25 T* models, covering everything from close-range viewing to more detailed long-range observation. ZEISS positions the series for nature observation, long-range viewing and game identification, while the compact dimensions also make these monoculars practical for sporting events, travel and theater use.

A defining feature across the line is ZEISS T* coating, which is adjusted to suit the individual lens for improved contrast and image clarity. The series also offers diopter adjustment up to plus or minus 4 diopters, helping users adapt the image to their eyesight without adding bulk. In practical terms, these monoculars are designed as highly portable optics that can be kept close at hand and brought into action quickly when a full-size binocular would be less convenient. Their compact construction and outdoor-oriented design make them a natural fit for users who want real optical reach in the smallest possible package.

About the Zeiss Mono 10x25 T*

The ZEISS Mono 10x25 T* is the highest-magnification model in the compact Mono range, built for users who want more reach without moving to a larger optic. Its 10x magnification is well suited to detailed observation at distance, whether that means checking game movement, reading terrain features, or following action at outdoor events. Paired with a 25 mm objective lens, it balances portability with enough light-gathering ability for daytime use and for maintaining useful contrast in subdued conditions.

The optical system uses a Schmidt/Pechan roof prism layout, which keeps the monocular slim and easy to pocket. ZEISS T* fully multicoated optics help deliver a clear, high-contrast image, and that matters most when brief viewing opportunities demand fast recognition rather than prolonged setup. A field of view of 88.00 m/1000m gives enough width to locate subjects efficiently, while the close focus of 4.50 m adds flexibility for nearby observation.

For practical day-to-day use, the Mono 10x25 T* also offers +/-4 dpt diopter adjustment, making it easier to tailor the image to individual eyesight. Its 77.00 g weight and 119.00 mm length make it easy to carry in a pocket, pack or glove compartment, so it is more likely to be with you when needed. Nitrogen filling, fogproof construction and waterproof protection support reliable use in changing weather, which is important for a monocular intended to travel light and go anywhere.

About Zeiss

ZEISS began when Carl Zeiss opened an optical and precision-mechanics workshop in Jena in 1846. Today, the company is headquartered in Oberkochen, Germany and is widely associated with precision optics across several fields. In sport optics, ZEISS develops binoculars, riflescopes and spotting scopes for hunting and outdoor use, with product families that cover both premium and more accessible segments.

For this category, ZEISS is especially known for optical technologies such as ZEISS T* lens coatings, used to improve contrast and image transmission, and LotuTec protective coatings on hunting optics. Its lineup also includes advanced products such as Victory RF binoculars that combine observation with ballistic functionality and app connectivity. That background in optical engineering is reflected in ZEISS monoculars, where compact size is paired with the same emphasis on clarity, mechanical precision and field practicality seen across the brand’s broader sport-optics range.
