I think all of you are wrong. If we talk about low light conditions, you should cosider 7x50, 8x56, 9x63. 7mm exit pupil makes even not fully multi coated bins better than high quality super ultra fancy high end robo model. Of course if your eyes are not 50+ years old I think. What doyou think of it?
Great insight into binoculars. Thank you. What would be the perfect binocular model for range shooting? Currently, I am debating between Diamondback HD 10X42 and 12X50. Please advice.
Here is the thing Binoculars have two numbers right, the power magnification and the lens diameter. as you know all ready the power number for exemple 7/32, 7 is the magnification of the object that you are seeing so if you see a deer or bird ect to 100 yards that lens the power 7 len is going to magnifi that object 7 times closer to your vision, now to understand you have to divide the power number by yards 100/7 that is= 14.3 yards away will appear to you. now the lens diameter or second number is refer to the diameter in millimeters of the object lenses from your eyes the large of the lenses diameter determines how much light your binocular can gather, imagine like a window example, for 7/35 binocular 35 divide by 7 equals to 5 mm this is the wide that you are gonna get in your view its call exit pupil size. I hope this will be useful for you!
I get confused when people say the 10x will bring in the object 10 times closer. I already understand when you say it makes the object 10 times larger, but 10 times closer is not clear. What are the 2 points in yards involved? 10 times closer from what? Is the object's starting point zero and the end point (100) is where you are standing?
You're right, that doesn't make sense, a 10x magnification will give you an image of the object as if it were at 1/10th of the distance it actually is.
Hi Jo Hig I know may be its a little bit late to answer your question but im going to help you any way.

Devide the distance of an object by 10. So if an object is 1000mtrs away it will look like if it where 100mtrs away, whereas a x8 will look like if its 125mtrs away.
Hola,me gustaria comprar unos levenhuk 16×42. Crees que es buena eleccion? Tengo buen pulso unica duda su zoom es real o tendra muchomenos aumentos que prome ten. Gracias
Tony, 87m/1000m is the FOV (field of view) of the binocular expressed in metric, rather than in imperial length. FOV is the width of landscape a person can see at 1,000 meters or 1,000 yards. To convert FOV from metric to imperial units - just multiply 87x3 =~ 261 ft/1000 yards. Or 261ft at 3,000 ft. distance. [that's not a precise conversion, but a common easy, quick thumb rule way of doing it. ] You can also determine FOV in degrees using the same numbers. The tangent of the FOV is 261ft/3000ft = 0.087. Arctan 0.087 = 4.97˚, [ Or in metric 87m/1000m = 0.087, where again the arctan of 0.087 = ~ 5˚ FOV. Hope that helps. btw, the only thing I might add to his explanation about a larger diameter exit pupil being better for seeing in dim light conditions. Is that largely applies to a younger person. For example: A 10x50 binocular will have an exit pupil of 5mm. A person less than 50 y.o. eye pupil will open that wide, or wider if even younger. And their eye will be able to taken in the entire 5 mm circle of light. But the ability of the eye pupil to open decreases with age. The dark light adapted eye of a 65 y.o. will only dilate to about 3.9mm. He would probably be able to see just as well in dim light with an 10x42 binocular, with an exit pupil of 4.2mm. Or maybe even with an 8x32 binocular with an exit pupil of 4.0mm. However, a higher quality binocular that transmits a higher percentage of the light taken in by the objective lens to the ocular lens exit pupil would also make the light inside a 4.2mm exit pupil a little brighter. That's one reason why one 10x42 binocular cost $200 and another 10x42 binocular cost $1000 or more. Better lens glass, & better quality lens coatings. However, a binocular with an exit pupil larger than what their eye can actually take in, may still provide an advantage in that, they need not perfectly align their eye's pupil to be centered on the exit pupil's circle of light. iow, the binocular may be a little easier to use.
The first numbers are the magnification. The last number is the size of the forward lens in millimeters. A 20-120x binoc will magnify an object 20-120x its normal size. The last number tells you the size of the forward lens(or objective lens). The bigger the number there, the bigger the lens, and the more light it will let into the binoculars. He wasn't clear on that.
100mtrs to 1000mtr means its a 10x65 10x being the magnification, 65 the object lens diameter. The 5° is the view of field you can see out of the 360° world we live in. For comparison; A human eye can see on average 120°which is 1/3rd of the 360°

Hugo Tarko i think dcf stands for roof (dach in german hence the d) central focusing and br means rubber guarded. ive owned the newer pentax 9x42 and they were a good all around package. certainly better than monarch 5s but they dont come close to high end resolution and colours in my experience
Hi. I wanted to buy binocular for traveling, supervision, bird wathing, but I can't choose model. My budget 150-200$. Now i watch 2 brands. Nikon and Vortex. So, my questions: 1. Nikon Prosstaf 7S or Vortex Diamondback? 2. Sizes and magnification, 8×42, 8×50, 10×42, 10×50 which one the better?
Jenishbek Muratbekov get diamondback 10×50s, they're more rugged and have a better warranty. I work at sportsmans warehouse and weve had lots of people return nikon's because the warranty is garbage. vortex will cover anything, even if its totally your fault.
