Find the best 8×21 binoculars as we review Bushnell Powerview, Pentax UCF-R & Galileo 8×21 roof prism binoculars. Learn what compact binoc is best for you!
If you want the most portable binoculars that offer crisp images when focusing in on something a medium-distance away, consider a pair of 8×21 binoculars. These aren’t going to give you the most amazing views in the world, but they’re still eons beyond opera or theatre glasses.
And even better than that: they’re cheap.
That’s OK though! The ones that are manufactured are quality optics for an affordable price.
8×21 Binoculars: Why Use Super Compact Binoculars
What could you possibly need such a small pair of binoculars for? Well, how about everything?
Ultra compact binocs like an 8×21 model are great for:
- Sporting events
- Nature walking
- Up-close bird watching
- Certain hunting excursions
These are great specs to have around the house for any number of different activities. And since they’re so small and affordable, they also make fantastic kids binoculars.
With most of the 8×21 models, you can keep them in a pocket or a bag without ever feeling their weight. These are glasses that can and do go absolutely anywhere you want to take them.
We really love these optics as a pair of hiking binoculars, as you can get decent optics for no weight in your pack.
The major drawback: Because the objective lens is so small and due to manufacturers not producing top-tier 8×21 optics, their performance is limited in badly lit areas.
