Optical Performance

Looking at the optical performances of these three Nikon Monarch 5 models, each one has its ups and downside. The step-up in magnification is one of them. You can choose which magnification you want and is between 8x,  10x and the 12x.

One of the obvious differences between them is the field of view. The field of view for the  8×42, 10×42 and 12×42 is obviously noticeable. Their field of views is; 330ft, 288ft, and 262ft at 1000yds respectively.

The smallest magnification has the widest field of view. This is not surprising because higher magnification binoculars usually come with a compromise in the field of view.

So, if you are a birder you might prefer the 8x model because of its wider field of view to enable you to see smaller birds as well. However, if it’s for other activities you might prefer a higher magnifying power. But it is worth keeping in mind that higher magnification will also magnify your handshakes which might cause unsteady images. But you can correct this by using a tripod or any mounting equipment.

The other obvious difference is the eye relief. The eye relief for the 8x,10x and 12x models are 19.6m, 18.4 and 15.4m respectively. It is very clear that the 8x magnification has the most generous eye relief. Even though they can all accommodate eyeglasses wears the longer the eye relief the better is it always.

As you can see, from the table of features and specification above, what you gain on with 12×42 Nikon Monarch 5, you lose in exit pupil size, the field of view and relative brightness.

All Nikon Monarch 5 binoculars are built with Nikon’s premium Extra-Low Dispersion glass for a sharper, clearer and good field of view. The lenses are fully multi-coated to provide better light transmission.

They are also 100% waterproof, fog-proof and have shockproof. With their rugged rubber-armored coating for durability, they can withstand all the bumps and bruises of riding around in your vehicle and carrying them through all kinds of outdoor terrain.

 

Price

As you can see the Nikon Monarch 5 binoculars are made to be affordable yet provide quality viewing for the outdoor enthusiasts. Even though these prices might have changed by the time you are reading this review, I  bet they won’t vary that much.

Weight and Dimensions

The Nikon Monarch 5 12×42 binoculars weigh 612.4g which is slightly higher than the Monarch 5 8×42  and  10×42 binoculars and with them weighing 590.0 g and 601 g respectively.
