Vortex Diamondback 10×50 vs 12×50 – Which binoculars are more versatile?

Vortex Diamondback 10x50 vs 12x50

To be a great hunter, you need to spot your prey from miles away and that’s where binoculars come in handy. Between the Vortex Diamondback 10×50 and the 12×50, which is the perfect selection for hunting?

Last year during the Deer Hunting Blind Open, I had a pair of great binoculars that were gifted to me by my fiancée. Unfortunately, I dropped them while sitting in my car. They fell off the armrest of my chair about 3 feet and knocked the optics out of alignment.

Now, as I browse through endless catalogs of available binoculars, I am looking to find a brand with some versatility to add some cool aspect to my beloved sport.

As a guy who also values high magnification, I still haven’t yet decided on which model between these two is most ideal for my deer hunting hobby. I suspect that I am not alone in this dilemma so I decided to share my in-depth research on the two to help you find the best for you too.

Vortex Diamondback 10×50 vs 12×50 – How do they compare?


Both the 10×50 and 12×50 binoculars are capable of transmitting more than enough light to your eyes through their 50mm diameter lens which makes it hard to differentiate the view quality between the two models.

Your eye’s pupil paired with the size of the shaft of light thatexits through the ocular lenses contributes to the image quality created. Thisis known as the exit pupil and the 10×50 gives a 5mm diameter while the 12x50offers one at 4.2 mm.

The 10×50 is Armortek coated while the 12×50 is fully coated andboth have been Argon gas purged to increase the binoculars resistance to reflectionand make them anti-fog and water-resistant. All these factorscontribute to the quality and quantity of light gathered by the binoculars.


These two do not have a big difference in weight (approx. 29 g)because the 12×50 requires heavier lenses and different mirrors to be able toproduce the 12x magnification. For external protection, the two models arerubber-coated but the 12×50 has a sleeker finish compared to 10×50.

These binoculars are both built with magnesium for their chassis and they use Argon gas inside the chamber which prevents any fogging which makes them perfect for viewing in any weather conditions.

To be able to comfortably rest your eyes on the binoculars, the diopter control knob on the right lens of both binoculars will help you set thebarrels to fit your specific eye difference.

While this feature on the 10×50 isnot lockable, on the 12×50, it is possible to unlock, make your preferredchanges and then lock them in place.

Because the 12×50 binoculars are fitted with Extra-low Dispersion glass and the 10×50 has Select glass elements, the quality of their lenses will not produce much chromatic aberration to cause you any inconvenience.

Another unique difference between them is that the Vortex Diamond 12×50 comes with an optional add-on lens that can be attached to the ocular lens to double the magnification power making it an alternative scope.

Field of View 

The 12×50 offers a 52-degree field of view which is 8 degreesless than the 10×50 piece which stands at 60 degrees. This wider scope makesfor more detailed viewing and tracking of fast-moving objects. Both binocularsoffer 6” of close focus and a 60-75mm interpupillary distance.

Eye relief is well catered to by both these binoculars with an insignificant difference in their effectiveness. The 10×50 offers 17mm while the 12×50 affords you 18mm which is quite forgiving and accommodating to spectacled individuals.

Can I convert my 12×50 Vortex Diamondback binoculars into a scope?

Yes, you can. These binoculars come with an extra pair of lenses that could be attached to the ocular lenses to double the magnification power of the binoculars essentially turning them into a valuable alternative scope.
