The Nikon Action range is a new line of binoculars from the optics giant, released in March 2026 to take over from the company’s now-discontinued Aculon range, which some users felt was plasticky and didn’t have enough eye relief. They can also be seen as a cheaper alternative to the Action Extreme range, which, while waterproof, are a lot heavier and cost more due to their enhanced durability.
I tested four models from the Action range, including the 7×50, 10×50, 16×50 and 10-22×50 zoom binoculars. The new models are not waterproof but are made from an aluminum alloy, which helps them strike a great middle ground between the Aculon and Action Extreme ranges. I tried them all for stargazing and found the 7×50 to be a great pair for beginners due to its low magnification and wide field of view, making it easier to star-hop and familiarize yourself with constellations.

Nikon Action 7×50 binoculars: Design
- BaK-4 Porro prisms
- Sturdy aluminum body
- Large focusing knob
The body of the Action 7×50 binoculars feels incredibly sturdy while also delivering on a weight of just over 2 lbs (935 g). They look big and heavy, but thanks to the aluminum alloy material used for the chassis, they are stronger than the plastic build of the Nikon Aculon binoculars and lighter than the Nikon Action Extreme binoculars. This is a huge plus for practical astronomy, as it will reduce fatigue when spending long sessions looking at constellations.
The 7x magnification and 50mm objective lenses make them perfect for beginner astronomy and a great first pair. 50mm objective lenses are a good size for letting in lots of starlight, so you get a bright view of the objects you are looking at.
Low 7x magnification is great for astronomy beginners for two reasons. First, it gives you a chance to practice keeping your hands steady, as small magnifications mean that hand tremors are amplified less while aiming at the sky. Second, the wider field of view makes it easier to hop between stars in a constellation, because you can keep them in view while identifying and moving between them.

The Porro prism design provides better internal light reflection without any coatings, which helps provide an image with strong light transmission. This simple prism design means that production costs are kept low while still providing a good image for the user. BaK-4 glass has a higher refractive index and produces a rounder exit pupil than BaK-7 glass, meaning better light transmission and edge-to-edge sharpness.
Nikon Action 7×50 binoculars: Performance
- A wide field of view (FOV) is good for locating objects
- Perfect for seeing constellation structure thanks to the wide FOV
- A massive exit pupil means eye alignment is easy
These binoculars are great for navigating the night sky and while they are perfect for beginners, they would also sit well in an experienced stargazer’s gear bag.
They excel in wide-field constellation observation and I used them to practice star hopping around the Big Dipper asterism, starting at Alkaid on the tail, to the double stars of Mizar and Alcor, then on to the stars of the bowl. I did the same with the Orion constellation and although I couldn’t make out the Orion Nebula (M42) in much detail, the lower magnification meant I could observe the surrounding stars of Orion more easily. I used them to star-hop from Castor to Pollux in Gemini and then moved diagonally to find the Beehive Cluster (M44) located within the triangle of Cancer. This took a few goes — it was easier with these binoculars as they have a wide field of view, but they did lack the more contrasted images of the cluster I got with the higher magnification models.
I also tested the Nikon Action 10×50 model alongside them, which would be more suitable for someone with astronomy experience who wants more magnified views of night sky objects, or some binoculars for more versatile daytime use, like bird-spotting. Optical performance was practically identical to the 7×50 model except for the increase in magnification. During testing, they offered a closer view of the Orion Nebula (M42), appearing more smudge-like and showing gaseous structure.
One huge benefit of these binoculars is the huge 7.1mm exit pupil. Unlike models with higher magnifications and smaller exit pupils, you don’t have to align your eyes with the eyecups perfectly to achieve a good view. While a larger exit pupil can make the background sky seem brighter, due to the exit pupil delivering sky glow from light pollution to your dilated pupils, the 7x50s offered an immersive night sky experience even when observing in a city park. All of this with a pretty sharp edge-to-edge view with minimal distortion. Obviously, if you took these to a dark sky site, the objects would be much more contrasted against the night sky thanks to a lower level of light pollution.
When I observed Jupiter, I was able to see the very faint line of the most easily observable Galilean moons but couldn’t resolve the individual moons at this magnification. For planetary observing, I would definitely recommend a pair with at least 15x magnification and using a tripod to steady the views. Alternatively, you could opt for a binocular with image stabilization if using a tripod isn’t possible or is deemed inconvenient.
Nikon Action 7×50 binoculars: Functionality
- Long eye-relief
- Hard eyecups can dig in
- Tripod adaptable
The binoculars’ aluminum chassis is covered in a rubberized coating, which helps when handling them because they grip better. This model is also only water-resistant, not fully waterproof, which means it would be fine in light rain or splashes but is not suitable for submersion or heavy rain.
Eyeglasses wearers will be pleased with almost 20mm of eye relief provided by the hard plastic eyecups, which can be stopped at four different preset heights.

I don’t wear eyeglasses, so while using these binoculars at the maximum eye relief and repeatedly aiming them upward, I felt like they were digging into my eye sockets. On the plus side, this does create another point of contact to prevent shake, but it’s definitely something to be aware of if you want to use these during extended sessions.

The Nikon logo in between the prisms unscrews to reveal a tripod mount, which is quite standard for many binoculars. This would be useful during longer sessions, when observing with a child who might get tired hands easily, or for those with grip strength issues or arm tremors.

The binoculars come with a thin neck strap, which is OK for casual use, but I would recommend something more padded if you want to carry these around for extended periods. The rubber eyecup cover stays fixed for protection during travel or when not in use.
The objective lens caps, however, come off easily and could easily get lost if not attached to the neck strap. I also found they can come off when getting the binoculars out of the carry case, which wasn’t a big worry, but might be risky if using them in dusty or sandy conditions, where you would want the lens caps on at all times except for direct observation.
How I tested the Nikon Action 7×50 binoculars
I tested the Nikon Action 7×50 binoculars in the city both during the day and at night. For stargazing, I tested them in a city park with a Bortle scale between 5 and 7. Our primary observation targets were the constellation Orion, Orion’s Belt, the Big Dipper, Jupiter and the Beehive Cluster in the constellation of Cancer. For terrestrial viewing, I used them during the day in parks for looking at small birds and squirrels.
During testing in the U.K., nighttime temperatures were on average between 46 and 54 degrees Fahrenheit (8-12 degrees Celsius).
User reviews
The Nikon Action 7×50 binoculars were announced in February 2026 and released in March 2026, so user reviews are still trickling in for this new model. Based on our testing, they are a great beginner pair of binoculars for astronomy and I think they are a great budget entry into the world of binoculars.
Should you buy the Nikon Action 7×50 binoculars?
Buy it if:
✅ You are a beginner stargazer: These are the perfect toolsfor learning the layout of the night sky, thanks to their low magnification and big objective lenses.
✅ You need a simple, wide-field pair: If you already own binoculars with stronger magnification and need a second pair for wide-field observing, these would be a great addition to your arsenal.
Don’t buy it if:
❌ You want close-up views of deep sky objects: The magnification is too low for serious deep sky observation. You can see some deep sky objects, but they are still quite small.
❌ You want the steadiest image possible: While 7x magnification doesn’t amplify hand shake too much, a model with image stabilization (IS) will provide the most stable viewing experience.
If you are a beginner to binoculars or stargazing, then I would highly recommend the Nikon Action 7×50 binoculars. Their low magnification means you get a wider field of view when using them, making it easier to star hop along constellations and locate night sky objects. They are a perfect tool for learning the celestial sphere of the night sky.
They sit at a price point of around $140, so while they are not the cheapest, they are relatively cheap for their class of binoculars. You are also getting high-quality optics from Nikon, with BaK-4 porro prisms that have strong light transmission with an approximate refractive index of 1.568-1.569
If the Nikon Action 7×50 binoculars aren’t for you
If the Nikon Action 7×50 binoculars are not for you, then you may want to try the other magnifications in their newly released Action range. I have tried the 10×50, 16×50 and 10-22×50 zoom models, the latter of which gives versatility in magnification.
If you are after pure deep sky observation, I would recommend the Celestron 25×100 binoculars, which need a tripod but have massive objective lenses for letting in plenty of light from dim nebulas and galaxies.
To take your stargazing experience to the next level, try a pair of image-stabilized binoculars. Our best overall pair is the Canon 10×42 L IS WP, which offers supreme control while scanning the skies and shake-free views at a 10x magnification.
