Olympus 10x50 Binoculars Review

The Olympus 10x50 binoculars are a popular choice for outdoor enthusiasts who want a reliable pair of binoculars without spending a fortune. In this review, we break down their design, performance, and value, and compare them with similar models to help you decide if they are right for you. Our editorial team compared specifications, buyer feedback and key decision factors.

Design and Build Quality

The Olympus 10x50 has a classic porro prism design with a rugged rubber armor coating that provides a secure, non-slip grip. The body is made of a durable polycarbonate material that feels solid in hand, though it is not as premium as magnesium alloy bodies found on more expensive models. The focus wheel is large and smooth, with just the right amount of resistance for precise adjustments. The diopter ring on the right eyepiece is easy to turn and stays in place once set.

At 31 ounces (880 grams), these are not lightweight. They are full-size binoculars, so expect some heft. The included neck strap is decent, but you may want to upgrade to a wider strap for comfort during long outings. The eyecups are twist-up with two positions, but they are not as smooth as some competitors. Overall, the build quality is good for the price, and they can handle the occasional bump or drop.

Optical Performance

The optics are the highlight here. The 50mm objective lenses gather plenty of light, making these binoculars perform well in low-light conditions like dawn and dusk. The multi-coated lenses (not fully multi-coated) reduce glare and improve light transmission, resulting in bright, clear images. The 10x magnification is powerful enough for detailed viewing, but it also means a narrower field of view (342 feet at 1000 yards) compared to 8x models. This can make it harder to track moving objects like birds.

Color fidelity is excellent, with natural tones and good contrast. Chromatic aberration (color fringing) is well controlled, though you may notice slight purple fringing on high-contrast edges. The close focus of 23 feet is not great for close-up observations, but it is typical for this class. For stargazing, the 10x50 configuration is a sweet spot, offering bright views of the moon and some deep-sky objects.

Handling and Ergonomics

The Olympus 10x50 are comfortable to hold for extended periods. The rubber armor provides a tactile grip, and the balance is good, with the weight centered between your hands. The focus wheel is positioned for easy access, and you can adjust it with your index finger without shifting your grip. The eyecups twist up and down, but they are a bit stiff, and the intermediate position is not very useful. If you wear glasses, the 12mm eye relief is a drawback, as you may have to press the eyecups down and hold them close to your eyes to see the full field.

These binoculars are not waterproof, but they are nitrogen-purged, which prevents internal fogging in humid conditions. They do not float, so be careful near water. The tripod adapter socket is a nice touch, but you will need to buy an adapter separately if you want to mount them.

Ease of Use

Setting up the binoculars is straightforward: adjust the diopter to match your eyes, then use the center focus. The focus wheel requires about two full turns from close to infinity, which is fine for most users. The diopter ring is a bit stiff, but that is not a problem once set. The twist-up eyecups are easy to use, though they do not have a click stop, so you have to judge the position. Overall, these are user-friendly binoculars that do not require a steep learning curve.

Cleaning and Maintenance

To keep the optics clear, use a soft brush or lens cloth to remove dust and smudges. The rubber armor can be wiped with a damp cloth. Avoid using harsh chemicals. Since they are not waterproof, store them in a dry place and use the included lens caps. The nitrogen purging means you do not have to worry about internal fogging, but you should still avoid extreme temperature changes.

Common Buyer Complaints

While most users are satisfied, some common complaints arise. The short eye relief is a frequent issue for eyeglass wearers, who report having to hold the binoculars at a distance to see the full image. Others mention the weight, especially when used for long periods. A few users have noted that the focus wheel can be a bit stiff in cold weather, but this is not universal. Some also wish the close focus were closer, as 23 feet is not ideal for backyard birding. Finally, the lack of waterproofing is a concern for those who want a rugged outdoor tool.

Comparison with Alternatives

To see how the Olympus 10x50 stack up, we compared them with the Nikon Aculon A211 10x50, the Celestron Nature DX 10x50, and the Bushnell Falcon 10x50.

• Nikon Aculon A211 10x50: The Nikon offers a similar design with a longer eye relief (15.8mm) and a slightly wider field of view (348 feet). It is about the same weight and price. The Nikon has a slightly better reputation for optics, but the Olympus has a more comfortable grip.
• Celestron Nature DX 10x50: This is a roof prism model that is more compact and waterproof. It is more expensive, but it has fully multi-coated optics and a closer focus (10 feet). If you need waterproofing and are willing to pay more, this is a better choice.
• Bushnell Falcon 10x50: The Falcon is a budget option that is lighter (24 oz) but has less robust build quality. It has a similar field of view but lacks the smooth focusing of the Olympus. If you are on a very tight budget, the Falcon is worth considering, but the Olympus is a step up in quality.

In summary, the Olympus 10x50 binoculars are a solid choice for those who prioritize optical quality and value over portability and waterproofing. They are best for casual birdwatching, hiking, and sports events, as long as you do not wear glasses. If you do wear glasses, look for a model with longer eye relief. For a waterproof option, consider the Celestron Nature DX.

Final Verdict

The Olympus 10x50 binoculars offer excellent value for money. They deliver bright, sharp images and are built to last. The main drawbacks are the short eye relief and the weight. If you can overlook those, you will get a reliable pair of binoculars that will serve you well for years. Check the current price on Amazon to see if they fit your budget.
