Nikon Monarch M5 Outdoor Binoculars 8x42

Product Information

On the other hand, the wider field of view means less eye relief--the distance between the ocular lens and your eye. If you wear eyeglasses the long eye relief feature comes into play. Eye relief should be greater than 16 millimeters if you wear eyeglasses to look through your binoculars.Eye relief of at least 19 millimeters makes viewing the entire field of view easy for nearly all eyeglass wearers, allowing us to see the full field of view. The Nikon Monarch M5 8x42 is among the best pair of binos we've found in its price range. The Monarch provides solid all-around performance and super crisp images, whether the sun is shining or not. Nikon gives a relative brightness for its 8x42 binoculars as 28.1. I think this is wrong. I get 27.5. They give exit pupil as 5.3 mm. But I think that is rounded up from 5.25. Thus the difference. In the table below I use Nikon's printed specs.] There's been a name change with these - they used to be called Monarch ATB Binoculars or the Monarch III, then the Monarch 5, and most recently named the Monarch M5 line. There are some other minor differences in the specs between the Monarch 5 and 7. These are so small as to not make a difference. But I present them here for completeness, and explain why these differences aren't important for determining which binocular is best for you.

What's the difference between the model 5 and model 7 versions of the Nikon Monarch birding binoculars?We consider this binocular a best buy in its price range. Its resolution and brightness compare well even when competing against binoculars costing up to twice as much. Even if some of the edges of the field of view is cut off for some eyeglass wearers because of shorter eye relief on Monarch 7, the field of view they can see is still wider than what they would get on the Monarch 5, even seeing all of it. The wider field of view on Monarch 7 more than makes up for the slightly shorter eye relief. How did I come to this conclusion? Let's take a look at the specs of the Nikon 5 vs 7 and compare them to what bird watchers need in a binocular. The MONARCH M5 is extremely light for this class of binocular. With all models weighing 640g or under, the MONARCH M5 is easy to carry on hikes, mountain climbs and various other outdoor activities. Extra-low dispersion (ED) glass for chromatic aberration compensation and brighter, clearer viewing

As it turned out, there were hardly any birds to be seen. (February, but little snow.) I never spotted anything unusual.The Monarch 5 has a longer 19.5 millimeters of eye relief--very good. The Monarch 7 has a shorter eye relief of 17.2 millimeters--average, which may cause some eyeglass wearers not to see both edges of the entire field of view. MONARCH M5, users can expect to visualise rich images in high-resolution, resulting in the magnificence of nature’s colours being brought to life. Both models feature a Dielectric high-reflective multilayer prism coating, to guarantee superior transmittance uniformity across the visible range. An improvement of new Monarch 5 over the older (ATB) model is that the new model can focus as close as 8.2 feet, compared to 9.8 feet in its predecessor.

Fully experience everything nature has to offer thanks to the MONARCH M5’s high optical performance. The binoculars feature fully multi-layer coated lenses and prisms, as well as a Dielectric high-reflective multilayer prism coating to ensure superior transmittance uniformity across the visible range, which results in brighter images and more natural colours. Meanwhile, its phase-correction coating minimises the loss of resolution to deliver high-contrast images.

A general idea of brightness can be determined by exit pupil--dividing the magnification into the objective lens size. Thus, 8x42 binoculars have an exit pupil of 5.25 mm. And 10x42 binoculars have an exit pupil of 4.2 mm. Relative brightness is the square of exit pupil. 8x42 binoculars have a relative brightness of 27.5*. 10x42 binoculars have a relative brightness of 17.6. Bird watching binoculars are typically within the range of 7-10x magnification. Most birding binoculars today are 8x (8 power magnification).

Really, that's only 5 inches difference. Not that much. Reviewers who have carefully measured the close focus distance have all discovered that the actual binoculars focus down to 7 feet or less--the rated number should be considered a maximum. 8 feet or less for close focus is good for these binoculars. It comes in two sizes, 8x42 and 10x42. They look the same and are the same size. We're discussing the 8x42 here, but the general characteristics are similar.For the price and all the below features, we really couldn't find a better deal. We use them for leisure
