Simmons 10X50 Binoculars Review
This Simmons ProSport 10X50 binocular has large 50 mm objective lenses, a great 5 mm exit pupil, and a wide field of view. Even better is its multi-coated optics on BK7 prism glass.
If you’re wondering how these big pair of eyes hold up in reviews, you’re not going to be disappointed. It has a strong rating that has plenty of reviewers giving it the double thumbs up. You might just chime in and agree once you’ve handled one of these.
Now, there’s some of us who are willing to spend a little more than $20, but not much more. With the old adage of “buy the best of what you can afford”, this $30-ish binocular might be the exemplar and it’s exactly why we decided to review it.
A large 50 mm objective lens binocular offered for less than $50! I had to let you low light hunters know about this baby.
So, how are you supposed to know if it’s going to see the stars or the twinkling of the night-stalking coyote in the shadows? By reading my Q&A, that’s how!
- Porro prism
- Tripod adaptable

ProSport 10X50 Binocular Q&A:
The objective lens size and light transmission debate has been a long time topic of controversy. For more on how large objective lens sizes can benefit your low light hunt, check out our full article for a complete run down.
But, if you want the short answer, I’ll give it to you here.
The idea is: the larger the objective lens size, the more ability the binocular has to let in more light. More light can mean a brighter image. A brighter image can improve your low light hunt. Can 50 mm lens do this? Yes, they can.
On this ProSport, if you combined the 50 mm size and the 5 mm exit pupil with the multi-coated lenses, you have the potential to get the brightest images possible for your eyes.
This means hunting longer, tracking animal movement and behavior in low light conditions, and getting a pretty wicked view of the night sky.
The various Simmons ProSport binoculars have either fully coated or multi-coated lenses. This particular ProSport 10X50 has the better of the two: the multi-coated.
This means that you’re getting multiple coatings on at least one lens in the entire optics assembly. The fact that a low budget brand provides a $100 treatment on a $30 binocular tells you that Simmons thinks their optics are worth it.
This Simmons ProSport 10X50 has the porro prism design that has the zig zag or traditional shape. You can tell immediately by the offset eyepieces to the objective lenses.
The nice advantages of the porro prism is you’re almost always going to get a wider field of view compared to a roof prism model with the same specs and they generally offer a greater depth of view. As a generality, porro prisms will have high-performing abilities for great value.
The downside is that they’re extremely difficult to weather-proof. This means that this 10X50, as well as all of the porro prism ProSports in Simmons’ line, are not waterproof or fogproof. They will also tend to be bulkier and heavier in build. The upside is, it’ll save you a little more in cost.
Unfortunately, the weight factor between the two types of binoculars isn’t limited to prism type alone – it’s a little trickier than that. Weight also includes several other factors such as magnification, variable zoom power, objective lens size, and what material the binocular is made out of.
But, for the sake of comparing the porro prisms with the roof prisms within the ProSport line, this 10X50 is 29 ounces. The same 10X50 with the roof prism is 28.5 ounces. In this case, the mere .5 ounce is negligible.
Even the porro prism 8-24X50 variable zoom binocular is one ounce more, making it a total 30 ounces.
And, to further emphasize that other factors affect overall weight, the porro prism 8-17X25 variable zoom binocular is an extremely light 10 ounces – even though it has variable zoom power versus the fixed 10X50. (Tip: as a general rule, variable zoom optics are usually heavier than fixed powers.)
It’s even less than half the weight of the lumbering 8-24X50! The obvious and significant weight-affecting elements here? The half-sized objective lenses and the slightly less maximum zoom power of the 8-17X25 binocular is what keeps it slim and trim.
In the end, a weight difference of a couple ounces between the porro prism and the roof prism ProSport binoculars is a non-issue.
This list is quite a bit smaller than the popular roof prism models, but they’re still show-stoppers in their own right. There is the 8X40 that is available in camo! The following models are only in the black finish and are the 10X50, 8-24X50, 10X25, and the 8-17X25.
- BK7 glass in porro prism design for optimal viewing quality
- Multi-coated optics for brilliant image quality and maximum light transmission
- Tripod adaptable for steady and still viewing
- Durable rubber armor body for secure gripping in wet and harsh conditions
Our Verdict on the 10X50 ProSport
To glass it up, the Simmons ProSport 10X50 will do the job just fine. According to the reviews, it was difficult to get it in focus, even with correct focusing techniques. This could be true of the 10X50 since the 12X50 binoculars seem to fare much better.
Speaking of the ProSport 12X50 binoculars, they’re large but they’re also fully weatherproof. It’s a roof prism, so it’s going to be a different visual experience versus the Porro prism 10X50 binoculars. But, for under $100, it might be worth checking out if you’re unsure about the 10X50 ProSports.
For a few bucks more, you can swing by the Celestron LandScout 10X50 binoculars. Celestron is owned by the same company that owns Bushnell who owns Simmons. We guess low costs and decent optics runs in the family.
Sticking with a family clan that knows optics best is the way to go when buying your first pair of binoculars. After all, an entry level binocular can light up the passion to starting your own binocular collection. From basic to pro level, Simmons can offer the right kinda price!
