Design and Build

Open Bridge Porro Prism Design

At the heart of the Steiner Predator AF 8×30 binoculars lies a traditional Porro prism design, offering a blend of optical prowess and ergonomic functionality. Unlike the more compact roof prism design, the Porro prism configuration affords several advantages. The wider separation of the objective lenses facilitates enhanced stereoscopic viewing and depth perception, particularly beneficial for focus-free binoculars like these. Moreover, the Porro prism shape fits naturally into the hands, ensuring a comfortable grip for extended periods of observation.

Main Chassis and Exterior Covering

Crafted from Makrolon® polycarbonate, the main chassis of the binoculars embodies a perfect balance of lightweight durability. Manufactured by Bayer, Makrolon® exhibits exceptional resistance to temperature-related expansion and contraction, safeguarding the optical alignment under diverse environmental conditions. The exterior is coated with NBR Long Life rubber, renowned for its resistance to oil, fuel, chemicals, sunlight, and heat, ensuring longevity and reliability even in the harshest of conditions.

Hinges and Inter-Pupillary Distance (IPD)

The binoculars feature robust hinges that maintain perfect alignment, even under significant force. The friction/resistance to movement strikes an ideal balance, preventing accidental misalignment while ensuring ease of adjustment. The Inter-Pupillary Distance (IPD) range, from 5.5cm to 7.2cm, caters to a wide spectrum of users, making these binoculars suitable for both adults and teenagers.

Waterproof and Fog Proof

Engineered for reliability in adverse conditions, the Steiner Predator AF 8×30 binoculars boast a fully sealed construction, filled with nitrogen to prevent fogging. This waterproof and fog-proof design ensures clear viewing in any weather, making the binoculars a dependable companion for outdoor enthusiasts.

Optical Performance

Always in Focus

True to their name, the Steiner Predator AF binoculars feature the “Always in Focus” system, eliminating the need for constant adjustments. Once the diopters are calibrated to match the user’s vision, everything from 20 yards to infinity remains consistently sharp, facilitating rapid target acquisition and seamless observation.

Diopter Adjustment

Each eyepiece is equipped with a diopter adjustment, offering enhanced customization and accommodating individual differences in vision. The dual diopter system provides a broader range of adjustments, allowing users to fine-tune the binoculars to their specific needs.


The soft silicone rubber eye-cups, coupled with the ergonomic design, ensure unparalleled comfort during extended use. The distinctive eye shield shape effectively blocks out peripheral light, enhancing immersion and focus. The fold-up/down design caters to both eyeglass wearers and non-wearers, providing flexibility and convenience.

The binoculars feature CAT™ (Color Adjusted Transmission) lens coatings, which optimize color contrast and visibility, particularly in wildlife observation scenarios. These coatings selectively enhance certain colors, making wildlife stand out against their surroundings. Additionally, the fully multi-coated optical system ensures maximum light transmission and image clarity.

Lenses and Prisms

The 30mm objective lenses, while slightly smaller than the standard 32mm, deliver exceptional optical performance, particularly in low-light conditions. The Porro prisms, crafted from N-BaK-4 HT glass by Schott, ensure uncompromising image quality and clarity.

Field of View (FOV) and Close Focus

With a FOV of 302ft at 1000 yards, these binoculars offer a mid-level view width suitable for various applications. However, the minimum focus distance of 60ft (18.3 meters) may limit close-range observation capabilities.

Image Quality

The image produced by the Steiner Predator AF 8×30 binoculars is characterized by its brightness, contrast, and color accuracy. Minimal color fringing and edge-to-edge sharpness ensure an immersive viewing experience, allowing users to discern fine details with ease.


Carry Case

Birdwatching with the Steiner Predator AF 8×30 Binoculars

Birdwatching is a hobby that combines patience, sharp observational skills, and a passion for nature. The right equipment can significantly enhance this experience, and the Steiner Predator AF 8×30 binoculars are a noteworthy option for birdwatchers. Here’s a detailed look at why these binoculars are well-suited for birdwatching, along with some considerations to keep in mind.

Advantages of the Steiner Predator AF 8×30 for Birdwatching

Auto-Focus System: One of the standout features of the Steiner Predator AF 8×30 is its Sports-Auto Focus system. This feature allows birdwatchers to maintain a sharp image without the need for constant manual focusing. This is particularly beneficial when tracking fast-moving birds or when observing birds in flight. Once set, the binoculars stay in focus from approximately 20 yards to infinity, allowing you to follow the action seamlessly.

Superior Image Quality: The binoculars offer 8x magnification, which is ideal for birdwatching as it provides enough power to see details without too much shake, which can be an issue with higher magnifications. The 30mm objective lenses gather ample light, ensuring bright and clear images. Additionally, Steiner’s proprietary lens coatings enhance color contrast and saturation, which helps in distinguishing birds from their often complex and camouflaged environments.

Wide Field of View: With a field of view of 302 feet at 1000 yards, these binoculars allow birdwatchers to scan wide areas effectively. This is particularly useful for spotting birds in dense foliage or across open fields. A wider field of view makes it easier to locate birds and follow their movements.

Lightweight and Ergonomic Design: Weighing in at just 19.4 ounces, the Steiner Predator AF 8×30 binoculars are lightweight enough to carry around for extended periods without causing fatigue. The ergonomic design, including comfortable eye cups and a balanced center of gravity, ensures that birdwatching sessions are enjoyable and strain-free.

Durability and Weather Resistance: Birdwatching often takes enthusiasts into various environments and weather conditions. The Steiner Predator AF 8×30 is built to withstand these challenges with its robust Makrolon polycarbonate housing and non-slip rubberized armor. The binoculars are also waterproof and fog-proof, thanks to their nitrogen-filled interior. This means they can handle rain, humidity, and even accidental submersion, ensuring reliability in the field.

Considerations for Birdwatchers

Close Focus Distance: While the auto-focus feature is excellent for medium to long-distance viewing, the Steiner Predator AF 8×30 binoculars have a close focus distance of around 20 yards. This makes them less suitable for observing birds at very close range. Birdwatchers who often find themselves needing to view birds up close, such as those in a backyard setting or at bird feeders, might need to consider binoculars with a shorter close focus distance.

Fixed Focus Range: The fixed focus range, while convenient, might not appeal to all birdwatchers. Some enthusiasts prefer the ability to fine-tune the focus for very specific distances, which is more easily done with binoculars featuring a central focus wheel. This level of control can be crucial in certain birdwatching scenarios, such as focusing on birds hidden in dense foliage or at varying distances in quick succession.

Price: The Steiner Predator AF 8×30 binoculars are positioned at a higher price point compared to some other models with similar specifications. While the features and build quality justify the cost for many users, budget-conscious birdwatchers might need to weigh the benefits against their budget.

The Steiner Predator AF 8×30 binoculars are a powerful tool for birdwatchers, offering a combination of advanced features, durability, and superior optical performance. The auto-focus system, wide field of view, and excellent image clarity make these binoculars particularly well-suited for tracking and observing birds in their natural habitats. While they may not be ideal for very close-range observations, their overall performance in various outdoor conditions makes them a reliable choice for serious birdwatchers. Whether you are scanning the treetops for a glimpse of a rare species or following the graceful flight of a hawk, the Steiner Predator AF 8×30 can enhance your birdwatching experience, bringing you closer to the wonders of avian life.
