Review NIKON Action Ex 12x50 Porro Prism Binoculars Multi coated Waterproof 50mm Black

The **Nikon Action EX 12 50 Porro Prism Binoculars (Model 632638)** are a robust and versatile optical instrument designed to deliver exceptional clarity, durability, and performance in demanding environments. Engineered with Nikon s signature precision, these binoculars combine a **12x magnification** with a **50mm objective lens diameter**, creating a balanced optical system ideal for outdoor enthusiasts, hunters, birdwatchers, and adventure seekers who demand both sharp detail and reliable functionality. The **Porro prism design** not only enhances image clarity with its classic, ergonomic shape but also provides a more natural, three-dimensional viewing experience compared to roof prism models, making them particularly well-suited for low-light conditions and extended use.

At the heart of these binoculars lies **multi-coated optics**, a proprietary Nikon technology that minimizes light reflection and maximizes light transmission through multiple layers of coatings on the lenses and prisms. This ensures vibrant, high-contrast images with reduced glare, even in bright sunlight or overcast skies, while also improving low-light performance for early morning or evening observations. The **50mm objective lenses** gather ample ambient light, further enhancing visibility in challenging conditions, making these binoculars a standout choice for activities like wildlife spotting, stargazing, or navigating rugged terrain.

Durability is a cornerstone of the Nikon Action EX series, and these binoculars are no exception. Built to withstand the rigors of outdoor adventures, they feature a **waterproof and fog-proof design**, thanks to an internal nitrogen purge and rubber armor that seals out moisture and dust. The rubberized grip not only provides a secure, non-slip hold but also offers added protection against impacts, ensuring the binoculars remain reliable whether you re hiking through dense forests, scanning coastal landscapes, or braving unpredictable weather. The **central focus wheel** allows for quick, precise adjustments between the two eyepieces, accommodating users with varying prescriptions or those who prefer a more personalized viewing experience.

The **compact yet sturdy construction** of the Nikon Action EX 12 50 makes them highly portable, fitting comfortably in a backpack or mounted on a tripod for extended use. The **close focus distance of just 10 feet (3 meters)** enables users to observe fine details up close, such as flowers, insects, or small wildlife, while the **wide 7.5-degree field of view** ensures a spacious, immersive perspective perfect for tracking fast-moving subjects like birds in flight or distant marine life. Whether you re a seasoned outdoorsman or a casual observer, the ergonomic design and intuitive controls of these binoculars make them an intuitive tool for exploration.

For those who prioritize both performance and practicality, the Nikon Action EX 12 50 Porro Prism Binoculars offer an outstanding blend of optical excellence and rugged reliability. Whether you re scanning the horizon for distant landmarks, studying the intricate patterns of a bird s plumage, or simply enjoying the beauty of nature, these binoculars deliver crisp, vivid images with every glance. Built to endure the elements while providing unmatched clarity, they are an indispensable companion for anyone who seeks to see the world with greater depth and precision.

The Nikon Action EX 12x50 Porro Prism Binoculars (model 632638) are a popular choice for outdoor enthusiasts, particularly for activities like birdwatching, hunting, and general viewing. Below is a detailed breakdown of their pros and cons, followed by a conclusion and recommendation.

---

The 12x magnification and 50mm objective lenses provide a good balance between field of view and detail. The 50mm aperture is bright enough for low-light conditions, such as dawn, dusk, or cloudy days, making it suitable for birdwatching or hunting. The multi-coated optics reduce glare and improve light transmission, resulting in clearer and more vibrant images.

Porro prisms are known for delivering a more natural, three-dimensional image compared to roof prisms. This design is often preferred by users who prioritize image quality and comfort over compactness. The wider field of view and less eye strain make it ideal for extended use.

These binoculars are fully waterproof and fogproof, thanks to their nitrogen-purged design and O-ring seals. This makes them durable for outdoor use in various weather conditions, including rain or humidity. The fogproof feature ensures that the lenses remain clear even in temperature changes.

Nikon is a reputable brand known for building high-quality, rugged optics. The Action EX series is designed to withstand rough handling, making it suitable for outdoor adventures like hiking, camping, or hunting. The rubber-armored body provides a secure grip and additional protection.

With a close focus of approximately 10 feet (3 meters), these binoculars are capable of detailed viewing of subjects at close range, such as flowers, insects, or small animals. This feature expands their versatility beyond traditional uses.

The binoculars offer generous eye relief (around 17mm), which is beneficial for users who wear glasses. This allows for comfortable viewing without the need to press the eyes too close to the ocular lenses.

The larger 50mm objective lenses gather more light, making them perform well in low-light conditions. This is particularly useful for early morning or late evening activities.

The rubberized coating on the body provides a non-slip grip and adds an extra layer of protection against scratches and impacts. The overall construction feels solid and well-engineered.

The 12x50 binoculars are larger and heavier than compact or travel-sized models. They weigh approximately 2.1 pounds (950 grams), which can be cumbersome for prolonged use, especially if you plan to carry them for extended periods or attach them to a tripod. This may not be ideal for travelers or those who prefer lightweight optics.

While the Porro prism design offers a more natural image, it typically results in a narrower field of view compared to roof prism binoculars of the same magnification. This can make it slightly more challenging to track moving subjects, such as birds in flight or fast-moving game.

The Nikon Action EX 12x50 binoculars are priced higher than many entry-level or mid-range binoculars. While they offer excellent performance, the cost may be a deterrent for budget-conscious buyers. However, they are often considered a good value for their quality and durability.

If you prefer lower magnification for broader views, these binoculars may not be the best choice. The 12x magnification is fixed, so you cannot adjust it for different viewing preferences.

While the multi-coated lenses reduce glare, large aperture binoculars like these can still be affected by direct sunlight or bright light sources. This may require additional care to avoid lens flare.

Although the binoculars are waterproof, the O-rings and seals require occasional maintenance to ensure they remain effective. Over time, the rubber can degrade, and the seals may need to be replaced or re-greased to maintain waterproofing.

The Nikon Action EX 12x50 Porro Prism Binoculars are a robust, high-performance option that excels in low-light conditions and offers excellent optical clarity. They are well-suited for outdoor activities such as birdwatching, hunting, and nature observation, where durability, waterproofing, and image quality are prioritized. The Porro prism design enhances the viewing experience by providing a more natural image, and the multi-coated optics ensure vibrant, detailed visuals.

However, their size and weight may be limiting factors for users who prefer compact or lightweight binoculars. Additionally, the fixed 12x magnification might not be ideal for those who prefer lower magnification for broader views. If you are willing to invest in a high-quality, durable pair of binoculars that perform exceptionally well in various outdoor conditions, these are an excellent choice. For users who prioritize portability or lower magnification, there may be more suitable alternatives.

If you are looking for a reliable, high-performance pair of binoculars for outdoor activities like birdwatching, hunting, or general nature viewing and do not mind the size and weight, the **Nikon Action EX 12x50 Porro Prism Binoculars** are an outstanding choice. Their waterproof and fogproof design, combined with excellent optical performance and durability, make them a versatile tool for enthusiasts.

For those who require more compact or lightweight binoculars, consider models like the Nikon Monarch 5 or the Vortex Viper HD, which offer a good balance between performance and portability. If you prefer a roof prism design for a wider field of view, the Nikon Prostaff 3S or the Zeiss Victory SF also provide excellent alternatives.

Ultimately, the Nikon Action EX 12x50 is ideal for users who prioritize image quality, durability, and low-light performance over compactness. If these features align with your needs, they will likely provide years of reliable service.
