Nikon Monarch M7 and Vortex Diamondback HD (2 Viewers)

[Naturebird]

I have a small Vortex Diamondback 8x32 that i often have in my car, and i use it a lot since its easy to bring. Since i like the format i bought a Nikon Monarch M7 8x30, to bring when i dont feel like using a bigger binocular.

There is not much price difference, the Vortex was about 250USD and the Nikon 370USD. The Nikon feels a bit more high quality, but the difference is small. They are also about the same size, and fits nicely into my jacket pocket. To me the Nikon is just slightly brighter, not much but just noticeably.

The biggest difference, and where the Nikon shines, is that the view is much wider. I think its a big difference, but the Nikon is 8,3 degrees, and the Vortex is 8,1 degrees in angular view. But the difference for the spectator feels a lot more than 0,2 degrees. Is there any other way to describe the field of view for the users eye? Im thinking that its about 40 degrees or something like that.

Maybe an expert here can explain what you are seeing.

8.1 = 426' FOV at 1000 yards and 8.3 = 435' FOV so I can't explain why you are seeing a "lot more FOV". If the M7 has a flatter field and the Vortex has a lot of edge distortion that could explain it. Both are good for the money. Enjoy the.

Are you talking about apparent field of view? (in degrees)

M7 don't have FF.
maintenance of sharpness of the fov is about 74% in M7 and 68% in Diamond

Dback's degree is bit larger then 8.1.
about 8.15

one theory about the FOV is if the owner where specs. Dback's ER is short for spec wearers. apparent Fov can be cut by about 2~5 degrees (even more to habit of the observer) depending on shape of specs

here is FOV comparison of Dback 8x32 and M7 8x30

there are taken at defferent situation because M7's photo is taken from former review I wrote a year ago.
and Dback's photo is taken few days ago for comparison against P7 8x30

but, amount of FOV taken by photo is always the same if it is well taken

you can compare the width of the two bin by amount of building that shown in photo.


And M7 Is everything better in terms of optics except for Pincusion distortion.
(maybe inflating of edge due to more Pincusion distortion of M7 can leads to more wider feeling.)


Dback 8x32's optic is closer to P7 8x30

Very nice and informative picture. I had both and think that while the DB HD 8x32 is great for the price (and warranty), the Monarch 7 (I had the old version) was overall better, brightness, sharpness, less CA... and then there's the "ring of reflection" that can be seen on the picture above and that has been spotted by several forum members, myself included. We talked about it here. I've seen this same ring of reflection on a 8x42 SVBony SV202 and recently on two different units of the 7x32 Pentax SD ED, this has been confirmed by other forum member as well. A sign of cost cutting, I guess.

I have seen all of the binos you said above and have seen other reflection bino such as BN 10x42, Alpen Teton, Svbony SV47 and BW25 (and more) but Dbak 8x32 was among the worst. much severe than 10x42 Dback.
two main critical disadvantages among with Short ER

I'm working on a review with P7 so I will come back sooner or later with this comparison or else

I found a binocular that has two angles to describe it. It has 125m/1000m field of view.

My Vortex Diamondback 8x32 has 8,1 degrees and 142m/1000m, and the Nikon Monarch M7 has 8,3 degrees and 145m/1000m. A very small difference, that feels a bit wider for the viewer. This "subjective" field of view isn't specified very often it seems.

I don’t follow this at all, and I have no idea where those field-of-view numbers at the bottom came from.

Maybe it’s me.

This article describes it well, with images. It doesn't say anything about apparent angle though, but i think its the angle from the sides of the image to the viewers eye that is mentioned in the listing i found.

Field of View Is Important in Birdwatching Binoculars. Here's Why

The two most important specifications for binoculars are the magnification and objective lens size (that's the "8" and the "42" in "8x42," respectively). But it's also worth paying attention to Field of View. Whereas magnification and objective lens determine how big and bright your image will be, f
