This is a comprehensive Zeiss Mono Monocular Review!

In this review, we will have an in-depth look at the specs, features, and different sizes available in Zeiss Monos.

The Carl Zeiss monocular securely attaches to the eyepiece of your binoculars with a small adaptor ring. On its own, you can use it as your mini telescope at a close range. 

The Zeiss Mono Monocular hales from Wetzlar, Germany, like most Zeiss products, especially sports optics. We all know the quality that we can associate with Zeiss, and with this price tag and the features, it’s the best deal for the money you can get from a top-notch brand.

There are six different sizes available in this Carl Zeiss mono model. The most popular one is the 10×25, especially among beginner wildlife enthusiasts. It allows them to convert their Zeiss binoculars into spotting scope and stomp long ranges without much weight. 

In the following two sections of this review, we will discuss some common features in all Zeiss Mono monocular sizes. Later sections of this review will highlight some individual features. 

Optical performance

Zeiss Mono monocular’s overall optical performance is exceptional and provides you with high contrast images even in low light conditions.

Lens quality

The Zeiss monocular scope comes with achromatic lenses, which means you won’t have to deal with any chromatic aberration even in twilight. Chromatic aberration is a color dispersion of an image.

These lenses bring two different wavelengths of light on the same plane, and you won’t see any purple fringing in your images caused by light dispersion. 

These lenses come with a T* coating on them, which means you will see sharp and high contrast images, irrespective of the light conditions. Due to Schmidt-Pechan prism, Zeiss Mono monocular stays sharp even if you look at a dark object in front of a bright backdrop. 

Image quality

The Zeiss close focus monocular device can produce bright, sharp, and high-quality images even in twilight conditions. All the credit goes to the achromatic lenses that Zeiss has used in this device.

These lenses can handle color fringing very well, and the displayed results will be as sharp as ever. The T* coating profoundly handles low light conditions, and you will get brighter images even in twilight.

Therefore, you won’t miss any details about enjoying a sporting event or observing wildlife and insects out there in the woods. 

Construction and quality

The overall construction quality of Zeiss Mono monocular is outstanding. It is designed to be lightweight so you can comfortably hold it in one hand or keep it in your pocket. 

Body and grip

The Zeiss Mono monocular has a very compact form factor and six different versions including a pen-shaped version, which you can easily keep in your pocket. Its housing is made of aluminum and is entirely splash-resistant. 

The aluminum construction makes it light and increases its operating temperature range between -4F to 104F. Therefore, you can use it in different weather conditions. 

Its small dimensions allow you to hold and grip your device with one hand. But you need to keep in mind this device doesn’t feature any water-resistant capabilities. So, you don’t want to pull it out on a rainy day. 

Focus wheel and focusing

The Zeiss Mono monocular comes with a focus ring on the eyepiece section. Using this ring is simple, and the movement is extremely fluid. 

However, the ring doesn’t offer much resistance, so the drive can comfortably get out of focus if it gets knocked around in your handbag or your pocket. 

Eventually, you will have to focus each time you take it out of your pocket, and that can be a little inconvenient if you don’t want to miss the action. 

Eyecups and lens covers

The Zeiss pocket monocular features a retractable rubber eyecup that ensures better eye relief and protects the lens. However, it doesn’t come with any lens covers, and you will have to purchase it separately. 

The eyecup is relatively stable and durable. But if you think your ocular device needs a lens cover, you can buy it because your purchase doesn’t include it. 

Zeiss Mono Monocular model sizes

The Zeiss Mono monocular is available in six different sizes, and the most popular one of them all is the 10×25 because of its better range and versatility. 

The following table provides you with a detailed overview of all the sizes available in Zeiss Mono monocular.

The Zeiss Mono 6×18 monocular is the sweet spot for stability and magnification in monoculars. Therefore, you can toss it in the backpack for the occasional birding due to its wide field of view of 360 feet at 1000 yards. But with a bigger objective lens and higher magnification, you can assess your target objects with more details. 

However, it still has a close range of fewer than 12 inches, so you can use it for reading numbers on the bus timetable up close comfortably. The device features a long eye relief of 15mm, allowing you to use it with your eyeglasses on.

Zeiss Mono 8×20 Monocular

The Zeiss Mono 8×20 monocular features an ever better objective lens with higher magnification that comfortably allows you to view longer distances. 

You can use this best mini monocular in the outdoors for birding and wildlife observation and can attach it with your Zeiss Conquest or Victory FL binoculars to turn them into a spotting scope for your hunting endeavors by tripling the magnification with the help of an eyepiece adapter.

With the help of an eyepiece ring adapter, you can connect this long-distance monocular with your Zeiss Victory FL and Conquest binoculars to use as your spotting scopes in your hunting excursions. 

The Zeiss monocular 10×25 features a field of view of 264 feet at 1000 yards, so you won’t miss out on any details on your distant targets when using its powerful magnification. 

Zeiss MiniQuick 5×10 Monocular

The Zeiss MiniQuick 5×10 monocular is geared towards using on the go and is best suited for explorers. If you don’t want to miss out on any activity while being outdoors watching birds or wildlife or in a stadium, you need to go with the Zeiss MiniQuick Monocular. 

This pen monocular is exceptionally lightweight and comfortable to hold for longer viewing sessions. Zeiss MiniQuick comes with an eye relief of 16 mm you can use it comfortably with your eyeglasses on as well. 

The Zeiss monocular also provides you with a wide field of view of 300 feet at 1000 yards so you can enjoy the blogger picture of the activity that is going on in front of you.

Zeiss Warranty

All Zeiss products, including these monoculars and their electronic components, are covered under a 2-year warranty. This warranty covers any issues or defects associated with the quality of the materials and craftsmanship.

However, it excludes loss or theft, or any cosmetic damage or alteration that influences your device’s overall performance. This warranty starts from the date of purchase and is not transferable under any circumstances. 

This warranty isn’t that much especially considering the price tag of Zeiss products and comparing it with other brands like Leupold and Vortex that offer unconditional and limited lifetime warranties on their products. 


One of Zeiss Monocular’s weaknesses is the smaller devices don’t come with any waterproofing features. The focus mechanism on all the sizes is quite fluid but is not resistant to any unwanted rotations. Therefore, you will have to refocus your ocular device each time you take it out of your handbag or pocket. 

The price tag is a bit high for a beginner but it’s worth every penny when you pair them with Zeiss binos as a spotting scope.

What’s in the box?

It includes everything you need to get going with your Zeiss ocular device. The quality of the pouch and the neck lanyard is undeniable. But Zeiss could have slipped in the lens cover that you will have to purchase separately afterward. 

Zeiss Mono user reviews

The Zeiss Mono monocular comes with an average user rating of 4.5 stars that is not bad. 

Most people have talked about how lightweight and convenient to use these binoculars are. People have also complimented how you can attach the monocular with your Zeiss binoculars with a simple ring adapter to triple the amplification for use as a spotting scope. 

Some people have also complained that the focus wheel is a bit too fluid, and you need to adjust it each time you take it out for viewing. 

This product is optically perfect but expensive. For an optics nut like me, it was worth every penny, though.
Pros: Zeiss quality optics
Cons: price.

  1. Nice summary, thanks 🙂 One remark though: mentioned eyepiece-adapter for conquest/victory just works with 3×12 mono. Not suitable for 8×20. Keep up the good work!
