In the next sections, we shall give you the details of each feature so you could see what’s in store for you when you buy the BL 15×56.

Allowable Operating Temperature

Well, this one is pretty basic but it’s important to know on what sort of temperature you can use this binocular.

Similar to the other two Minox binoculars we have reviewed, the BL 15×56 is also designed to operate on a temperature range of 14 °F to 122 °F (or -10 °C up to 50 °C) which is a pretty big range making this model applicable to most outdoor purposes.

Lens System

The BL 15×56 gives you excellent optical performance thanks to its lens system that comes fully multi-coated using Minox proprietary “M* Multi-Layer Lens Coating” with Phase-Corrected Prisms.

No matter where you are or what lighting you’re in, this binocular is awesome because of the 21 layers of optical coatings applied to all glass/air surfaces for maximum light transmission.

This results to high image resolution and contrast giving you neutral color rendition, clear views and stunningly bright images.

The Field of View (FOV) of the BL 15×56 is 234.6 feet at 1,000 yards (or 4.1°, or 71.5 meters at 1,000 meters).

It’s got a front lens diameter of 2.2 inches (56 mm) and with a magnification power of 15x, this makes an Exit Pupil Diameter of 0.28 inch (7.0 mm). The Close Distance Focus capability of this binocular is 23 feet (or 7.0 m).


The BL 15×56 comes with a fix power (magnification) of 15x which means that you do not have the capability to vary its power.

The 15x means your view is magnified fifteen (15) times compare to when you view an object using just your eyes which makes this binocular ideal to view objects and things from long distances.


The body of the BL 15×56, which is of the comfort bridge design, is really sturdy and yet construction is pretty lightweight considering it has a big front lens.

It has a metal focusing wheel with rubber ribs which makes it easy to use and adjust. There’s also a finger-felt marking for the infinity setting which enables user to quickly focus on the objects in view.

While the outside looks of this binocular is great, the inner part is awesome as well. The internal is Argon purged (better than nitrogen) to eliminate fogging and the entire optical assembly is sealed for waterproof performance down to a depth of 16.4 feet (or 5 meters).

Other Features

The BL 15×56 comes with turnable eyecups which is ideal for eyeglass wearers. The turning or twisting action of the eyecups provide for an overall eye relief of 0.69 inch (17.4 mm). This is a pretty generous eye relief which makes it easier for those who wear glasses.

The wide carrying nylon strap is also a welcome feature as it makes it more comfortable to carry along. It also comes with a case and rainguard.

Another convenient thing is the built-in tripod adapter. When holding the binocular is getting a bit harder, you’ll be thankful that this binocular has this feature.
