This is a 10x magnification for these binoculars. That makes them equivalent to an optical view of 42mrad across the entire field of view, which is pretty good. The magnification should be enough to provide sharp views even when you’re trying to look at distant objects at night or when you’re in the midst of dense city light pollution.

This particular Diamondback unit features a 42mm objective lens diameter. That’s quite large for a roof prism and will strike most people as rather unusual. This is, however, the same diameter that you’ll find among many of the higher tier optics on the market today, including many of the more expensive options. This size is great for making sure you have a large field of view at all times while still retaining some level of optical quality. Read next – best vortex hunting binoculars

Buyer’s Guide

There are a lot of factors to consider when looking for standard quality binoculars. The four most important things to think about are the magnification, the field of view, and how easy they are to use.


The higher the magnification that your binoculars have the better your field of view will be since it’ll allow you to see more of your subject even if they’re far away. For example, a 10×40 binocular will allow you to see a larger area within 100 yards than a 10×42 would at 1000 yards.

The best magnification to use depends on the type of binoculars you’re looking at, but if you’re looking for something high end then you should at least consider getting binoculars that have a magnification of at least 10x.

Objective Lens

There are many binoculars that have both 42mm and 50mm objectives on the market. These two values are actually the standard values for roof prism binoculars. A key factor in determining which is best for you will be seeing whether or not the binoculars you’re looking at are water proof or water resistant. This is because if they are not waterproof, you’ll want to avoid getting them wet, especially with a larger objective lens, since they will likely develop fogging issues once they get even a little bit wet.

Field of View

The field of view is the area that your binoculars can see within while using them. For example, if your binoculars let you see 100 yards then they’ll be able to see twice as much over the regular 10x magnification set.

The field of view depends on how big or small your target is so if they’re close to another object like trees or buildings then more focus might be needed. If you’re trying to find the binoculars with the highest field of view then it’s best to look for ones that have an objective lens diameter of at least 50mm.

Ease of Use

The ease of use is also very important since it will let you see whatever you want to without having to worry about adjusting your binoculars or moving around too much. This includes things like how well they fit into your hands, how well they focus, and how easy it is to adjust each eyepiece.

The best way to find the binoculars with the best ease of use is by looking for ones that have a larger eye relief which will let you keep your eyes open longer without having to move your head too much. The other thing you should look for is plenty of focus options so you can adjust them for any type of target with no trouble.

These four factors are important to most people when it comes to buying a new pair of binoculars, but most people don’t consider how they perform under various types of weather conditions or how easy they are to use.

Final words

If you’re looking for a set of binoculars that will last you a long time and perform well in all types of weather then consider getting one that has an objective lens diameter of at least 50mm. If you’re just looking for something that’s good enough that won’t break the bank then any binocular under $400 should be your top choice.

The happy journey begins!
