Understanding Binoculars: Magnification

[@brotherbreeze8351]

I wish everyone who posts videos on YT were as succinct, clear, and informative as you two. That is one of the best made videos I've seen on YT in years. And it helped me tremendously. Thank you both!

[@losscangers6513]

One of the best videos I've seen on youtube. Kept it short, easy to understand with great examples. Very good.

[@eagleopticsvids]

We really appreciate your input and comment! Thank you so much for watching!

[@DIGITALCANADA]

Just wanted to convey my thanks and gratitude in explaining this magnification issue and 10x40 time numbers. It was confusing but your 4 minutes video was worth every second. Thank you!

[@Prodaddyadventures]

Very informative video and not that lengthy. Great stuff

If you are reading this, you guys are amazing. This was simply great to understand. And the voices of birds.

[@neneb5232]

It helped me learn a lot about binoculars before I just jumped up and bought some. Thanks a lot this really helps me decide what kind of binocular I want in time for my birthday this month! God bless you and have a wonderful day!

[@terryarnold9154]

Thank you for posting this, as a novice i found the information to be clearly given, very well presented and useful too. Thanks again.

[@Sawar72]

Thank you so much, and my respect to you guys who actually make an effort to share their knowledge and help people like me to decide or understand. Once again thank you.

[@beckstervanc4947]

thanks for the lesson! I had no idea when it came to understanding the magnification of binoculars, but now I feel more confident!!

[@eagleopticsvids]

We're so glad you enjoyed this video! Thanks for watching!

[@eagleopticsvids]

@MrFoxracing19 A 12x50 is about the largest binocular that most people can handhold comfortably. When you get larger than that it can become to heavy and the image will be very hard to hold steady. I would recommend that if you need more magnification you look into a spotting scope. You could get a 50mm-65mm scope that would still be fairly light and compact, but will have 15-60x zoom.

[@renees1021]

Thank you. Have watched several videos before yours only to be left more confused. Your teaching method is excellent!

[@curmudgeon632]

Thank you. I knew absolutely nothing about binoculars. This video was very helpful in understanding my buying options.

[@eagleopticsvids]

Thank you so much for watching! We're glad to hear that the video made the process a little easier for you.

[@GeorgeMcPierce]

Very nice video explaining as simple as it could ever be explained even for the most ignorant. Congrats guys!

[@channel4svisitor388]

As a keen and active member of the Cloudy Nights Binocular Forum you may realist that I have a special interest in many aspects of binoculars. A few months ago , a long -running "discussion" I was involved with over on the Astronomer forums , that included input from Ed Nazarene , was focused specifically on the various real and apparent effects on resolution , governed by varying objective diameters and exit -pupils. Thanks All binoculars Viewer.

[@eagleopticsvids]

Thanks for watching!

That's wonderful to hear! Thank you for watching!

[@falcoperegrinus82]

@MultiJello123 I've been using 10x50 since I started birding and I think this is the best setup. I like having the extra magnification and with 50mm objective lenses, you get decent fov and brightness.

[@TheeGam3]

informative, thanks. I'm trying to source a pair of fog/waterproof binos for my paddling/camping trips. I'd like as big objective as possible while mainitaining a packable size product. bak4 seems better than porro for me because the offset binos take up more space and seem to be heavier as well. can you recommend anything that won't require a new mortgage? I'd like at least 6x but I think 8x would be best, and an objective in the 40 range.

[@BeingDengineer]

Nice video. Should I choose a good binoculars or a refractor telescope for viewing moon stars galaxies and land objects clearly...!

[@MRGOOPY123]

good video guys ive just purchased the olympus 8-16x40 zoom binoculars what do you think of them cheers

[@jonathanmoore5709]

also whats the turning wheel thats on one of the optic lens for

[@eagleopticsvids]

Binoculars are designed so that the image will be rotated several times and end up in line with the original orientation of the light entering the objective lenses. There are several prism designs that are used; Porro prisms and Roof prisms like the Abbe-Koenig and Schmidt-Pechan designs, and several others. All of these designs will reflect light in different ways but will always present an image that is in line with the original orientation.

[@majinbuu4754]

Hi eagle optics Id like to know what you guys think about Tesco 10x50. Is tasco a good brand for binoculars?

[@eagleopticsvids]

You are correct. A 10x magnification is a fixed magnification binocular. If a binocular has a zoom feature the binocular will typically list the magnification range, like 10-22x.

[@abhishekpratapsingh1031]

Can you please tell something about the graduation or scales marked on the lences of binoculars or scopes ?

[@nefter1]

this was awesome stuff, very informative, thank you so much for taking the time to let us know the "rookies" on what to look for and this very interesting video.

[@MrFoxracing19]

@eagleopticsvids Thanks.. i need something with zooming power for looking way down the feilds but i need something i can carry around in the woods, so not to big and heavy. I payed around 70 for the bushnell pair i have now.. I will keep a eye out at walmart and hunting places for a scope.

[@juan71685]

Any recommendations for binoculars,? Hunting, and I also like to look around but will mainly be for hunting.

[@TomisaLami]

Thank you for the video. But what is eight times a maltiple of? Like is it cutting the Dustin's in half or something?

[@eagleopticsvids]

Unfortunately I am not very familiar with the Barska 8x22 binocular, however any time you start adding things like cameras to a binocular you are sacrificing both the size/weight of the binocular and also the optics. If you don't need the camera as part of the binocular setup I would recommend looking into a different compact binocular so you can have sharper, brighter, more enjoyable views.

[@eddiegreenslade8970]

does this apply to rifle scopes also. If so what magnification would you recommend for target shooting up to a 1000 yards to get a clear picture...thanks

[@eagleopticsvids]

Eddie, I'd imagine a lot of the same principles apply for rifle scopes but Eagle Optics does not specialize in rifle scopes. I'd recommend giving our sister company, Vortex Optics, a call for any rifle scope questions. Phone: [phone] or [phone] or Email: [e-mail]. Thanks for watching!

[@guillermomaura4447]

Thanks, it help me a lot in understanding binocular magnification. Excelent video.

[@rares883]

Doesn't matter,I've bought it yesterday and I'm very happy with it :) I didn't expect it to be so great :D,Can you give me an advice on cleaning it's lens in the future please?

[@ashton0966]

Thanks ! I'm looking for a binocular for the purpose of helicopter spotting, but for multi use also. 10x42 was suggested to me.. would this be accurate ?

[@eagleopticsvids]

There are advantages to both. The Roof prism binocular will typically be more compact and lighter, with a better close focus, and better weatherproofing. The Porro prism binocular is going to have better depth of field, and since its prisms are easier to manufacture and align you typically get optics with less chromatic aberration for the same price.

[@itzvincentx3]

Hi, I want to ask if a Barska 8x22mm Point N View Digital Camera Binoculars is good for viewing concerts or sporting events? Is it a good binocular to see people and things clearly?

[@yourtube20061]

what does this mean "20-140x70mm" - as written in one of the vids on the side ? means the binoc has a variable magnification of 20 to 140 x ?

[@morethanblackandwhite]

Thank you for the informative video. It was professional and concise, and I'm walking away with just what I wanted to know. Take care.

[@rayo631]

so clear and concise just like your optics

[@jiwankhatiwada3647]

Very Helpful.which binoculars is good for vewing stars.

[@raeesauxbeat8807]

Can u suggest which binocular is the best for long distance view

[@asseenontvstuff]

What are the best pair of compact, lightweight binoculars for the average person?

[@RatRaceAce]

Regarding 234FT/1000yds at 10x: This refers to the field of vision of your binoculars. It means that when you set the magnification to 10x (lowest setting), at a distance of 1000 yards the left-to-right width (field of vision) that you can see through the binoculars is 234 feet. The same thing is also given roughly in metres, as 78m/1000m at 10x. As you increase the magnification the field of vision will decrease. As for 10x90x80, I have no idea why there are three numbers.

[@mannu7554]

Thank you so much......just wanted your opinion on birdwatching binoculars. If 10×50 would be better or 20×50 ?

[@captainmarvel9610]

10x50 imo. 20x50 they would be hard to see as field of view is deceased

[@TimKollat]

Just let me know what is the best poro design in an 8x? I bought the leupold Yosemite in 8x30 and although the view through them was great, the eye cups were abysmal. The right eye cup is so loose it falls down. I took it back and tried another two in the store, same deal...left eye cup sturdy, right eye cup loose and easily falls.Also focus wheel is gritty. I exchanged for the Vortex Raptors in 6.5x32 and the eye cups are great, also focus knob WAY better. I want a good 8x30-ish poro and am about to get the same Raptors from Vortex in 8.5x32 unless there is something better? The Leupold Yosemites would be great if it wasn't for the super cheesy eye cups and gritty focus wheel. If I have to step up to an 8x42 then I will, but I like the light compact design of the Vortex Raptors...is there anything better than these for the price?

[@mambaman2007]

That's all it took to demystify this numbers. Thank you so very much for this video.

[@madforit9661]

Are you using a camera attached to the binoculars to show us the images or is it a webcam held to the lens Great video but i wish to attach a camera to my binoculars but am look where to find the product that does this

[@Sasko97]

Hi, does not the binoculars have zoom in and zoom out function ? I have one made for the army by the 'Zrak' optics, and it has the ability to zoom in while viewing farther objects and to zoom out while viewing closer, is this unique or all binoculars have it ?

[@ubreakitirepairit3569]

You guys said that the size of the binoculars have no bearing on the magnification, but did not explain anything pertaining to the different sizes. Why would any one choose the bigger ones over the smaller ones or the smaller ones over the bigger ones?

[@AmienPhillips]

Very helpful thanks, i have wondered what those numbers meant for decades

[@eagleopticsvids]

@gunner5876 Most situations 8x will be enough magnification, however some people like to use 10x for a bit of extra magnification. The one concern is that it can be hard to hold steady. You'll probably have noticeable eye fatigue with prolonged hand-held use of a binocular with more than 10x. For a good entry level binocular I'd recommend spending more than $60, more like $100-$150. Quality is higher with these binoculars, so they'll last longer with better optics.

[@YTeradicant]

are there any you could recommend that cam see a far distance like 1 mile?

[@eagleopticsvids]

That's a great question! Any binocular you get is going to let you see a mile away, just as you can see something a mile away with the human eye. Depending on what you are trying to see at that distance will help determine which magnification binocular you should get. One thing to keep in mind when purchasing binoculars is that the higher quality glass and lens coatings in an ED/HD binocular versus a non-ED/HD binocular will also affect what you can see at those distances. The higher quality optics will allow you a brighter image with better clarity and color tone, as well as sharper resolution. If we can help you any more please check out our other videos on Understanding Optics. kzbin.info/www/bejne/hn2keY2fltiCmNk or call us at 800-289-1132 to speak to a specialist! Thank you!

[@amalkant63]

Thanks highly use full video & info. If 8 in [8-16x25 zoom] spec.is magnification, what is 16? Does this additional 25 zoom brings object closer &sharper? Kindly inform.

[@eagleopticsvids]

An 8-16x25 binocular has a magnification range of 8x to 16x, and the 25 refers to the diameter of the objective lens in millimeters. This is a good indicator of how bright the binocular will be, as this number increases so does the brightness of the view. Overall though an 8-16x25 will not be a very bright binocular, especially at the higher magnifications, however the binocular will bring objects pretty close with the high magnifications.

[@hammadaliabbasi]

Thank you so much for making such a useful video. I want to buy a binocular whose range is up to five kilometers. Through which I can certainly see moving a living creature from five kilometres distance. So which one binoculars are best for my requirement?

[@petenicezz]

Marielle Salonga I found one and planing to buy it next month on amazon, Celestron 71008 SkyMaster 25x70 Binoculars. 25 being the closes view compare to 8 good to use with a tripod to keep it steady.

[@Miggys.Garage]

Me too I am on same boat, I did all my research, and I am willing to hope for extra dark skies to use up all the extra aperture. But I found the orion mini giants. I ordered the 9X63s they have 15X 63 just in case you are ok with a tripod.. they have like 5 degrees fov from which I would imagine is slightly constricted.....but fuck it first good pair, then down the road get the 25X100or80 s

[@owoewrefi]

Hi. Thanks. This was very helpfull. At the moment I'm planning to purchase a binocular 12 x 50 for birding. Would you recommend that ? Thanks in advance!

[@czarzenana5125]

12x is too strong to keep steady and 50 might be a bit heavy in weight as well. Most birders go for 8x42 or 10x42. The differences are not very big, in general: 8x has a bit wider field of view (you are less zoomed in) 8x has a little advantage in bad light conditions 8x is a bit easier to keep steady 10x brings the birds/objects a little bit closer Just test them yourself, something you should always do when buying binoculars.

[@eagleopticsvids]

Thank you for watching! I'd recommend not going any higher than a 10x binocular for birding as it is nearly impossible to hold a 12x steady for birding. Most birders enjoy using any of the following sizes: 8x32, 8x42, 10x42, and 10x50. As you increase either the aperture or magnification your field of view will narrow which can make finding the bird a little more challenging. Let us know if we can help with anything else!

[@boxing1039]

gee wiz Thanks a million I looked all over the Binocular and it was no help. Now checking your video and now I under stand. Thank you.

[@marioarias6413]

8x is my favorite magnification, enough for a good view without much shake.

[@eagleopticsvids]

@yourtube20061 Yes, it would mean the binocular has a variable zoom magnification from 10-140x. It's been my experience that this also means it's likely a binocular to be avoided! Cheers, Ben

[@tigers9571]

Ok great, now I have a better understanding about the 8 and 10. But please explain the 42? what does that number mean?

[@lawrancewilson8751]

Can you tell to me,up to what distance we can see an object by using 12x binoculars?!?

[@nigelperren5714]

Short but almost sickly sweet! Great little video,thanks!

[@eagleopticsvids]

Thank you for watching!

[@eagleopticsvids]

I would typically not recommend a 12x power binocular for general nature viewing. That magnification can be very hard to hold steady, with the small 25mm objective lens it will also not be very bright, and the close focus on that binocular is ~15 feet away from you. I would recommend looking into an 8x magnification, as this will be a much more enjoyable magnification to use in general nature viewing.

[@qtechgr]

So what is the difference of the same 8x with the different objective lens?

[@eagleopticsvids]

Hi! Thank you for watching. If you keep the same magnification and increase your aperture (42mm to 50mm) you will gain more light but the size and weight will be affected and your field of view will narrow. If you decrease the aperture (42mm to 32mm) you will lose light and resolution but gain a smaller more lighter weight binocular and a wider field of view.

[@Bear_83]

This was good. Just got me my first binocular a Brunto echo 8x42. Now i understand the meaning 8x42.

[@petesessa2041]

[@eagleopticsvids]

If you're looking for a compact Bushnell binocular with optics similar to the Legend Ultra HD 10x42 I would recommend the Bushnell Custom Compact Elite 7x26 (www.eagleoptics.com/binoculars/bushnell/bushnell-elite-7x26-custom-compact-binocular).

[@stevebovis8256]

Hi, a great well explained useful video, however the field of view section was a little misleading in that at zero magnification you are positioned central on the image and the same again at 10x magnification, at 8x you are positioned to the left of the image so in fact you still would not see Ben in full. Thanks for a nice easy to understand video.

[@xsauce3858]

can i modify my binocular magnification by using a smaller eyepiece like a 6mm instead of a 15 mm which is standard on my binocular?

[@eagleopticsvids]

Hi! Thanks for watching! If you binocular is a fixed magnification (8x42 or 10x50 etc.) the only way to change the magnification would be to add something like this doubler: www.eagleoptics.com/collections/binocular-accessories/products/vortex-2x-doubler-for-vortex-binoculars1. If we can help with anything else please let us know!

[@eagleopticsvids]

You would need quality optics with high magnification, and be able to hold the view steady, preferably by using a tripod. I would say a good quality full size spotting scope could possibly do this using 60x magnification.

[@kostasmiki]

very very good explanation. Well done!

[@oliverhyme478]

From the naked eye view, how far are you from the camera,pls? thanks!

[@eagleopticsvids]

[@oliverhyme478]

what would be good for a kpop concert,pls? I think the stage is at least 30 or 40feet away from my seat and I only have these two options - minox bv 8x25 brw or pentax papilio 6.5x21. which one should I get? I'm myopic and I wear glasses,too. Thanks.

[@eagleopticsvids]

The Minox BV 8x25 will give you a little more magnification so you can see your subject a little closer and is a little more compact in size. The Pentax Papilio 6.5x21 will be a little easier to hold steady and has an especially close focus, which may not be important for your use.

[@LegoTornado123]

what binoculars would I need o see the livery on planes in the sky?

[@eagleopticsvids]

Everyone will have a different tolerance for weight, however most people have a hard time maintaining a steady image at magnifications higher than 12x. They'll have a shaky image that will fatigue their eyes very quickly, and may find that they get headaches after prolonged use. Also the binocular that you mentioned weighs more than many spotting scopes.

[@QuickQuips]

I'd like to see a video comparing zoom and fixed length binoculars. Apparently the zoom ones have a very narrow field of view in comparison with a fixed one of the same magnification.

[@merobeach]

what do you recommend for night view

[@eagleopticsvids]

Thank you for watching! None of the binoculars that Eagle Optics sells will have night vision. With that said, you would want as much light hitting your eyes as possible for night viewing. There are a couple of factors to consider. 1. Check the exit pupil of a binocular and make sure it's at least 5mm. You can do this by dividing the aperture of a binocular by the magnification. For example, an 8x42 binocular would be 42/8=5.25mm. Our eyes usually dilate to at least that in low light so you want as much light to reach your pupil as possible. 2. The larger the aperture the more light coming in. Aperture refers to the front lens size. In an 8x42 binocular, the aperture is 42mm. In a 10x50 binocular the aperture is 50mm. Again, thanks for watching and if you would like to learn more please don't hesitate to contact us or look at our LEARN page here: www.eagleoptics.com/pages/learn

[@aseeroha]

So, I have a binocular that says 60x90 does this mean I see objects 60 times closer that the naked eye? and what is the most powerful binocular?

[@eagleopticsvids]

+Hassan ALSAUD Yes, your 60x90 binoculars indicate that you are seeing objects 60 times greater than the naked eye. The 90 represents the size of your objective lens, which are the light gathering lens. If you have any further questions please don't hesitate to ask us at 800-289-1132! Thanks!

[@aseeroha]

Eagle Optics thank you But somethings don't add up. I bought mine for 100 UAE Dirhams which is about $30 US. That's like 8 years ago. Now I see 8x42 binoculars for double that price on Amazon. So why is a lower magnification cost more?

[@eagleopticsvids]

That's a great question! Usually as you increase the price in binoculars you are paying for improved glass and lens coatings, which in turn offer better light resolution and a brighter image.

[@aseeroha]

Eagle Optics got it. Thanks

[@eagleopticsvids]

You are very welcome! Thank you for watching our video(s)!

[@PhillRobinson]

what would recommend as a star gazing binocular?

[@eagleopticsvids]

Thank you for watching and your interest with Eagle Optics! I'd recommend starting with something that's at least a 10x50 configuration. Depending on your budget I'd say the Eagle Optics Ranger ED 10x50 www.eagleoptics.com/products/eagle-optics-ranger-ed-10x50-binocular is a favorite among Eagle Optics. Please contact us if we can help with anything else!

[@santoshkiran1448]

Eagle Optics You explained Magnification, but didn't tell at what distance.

[@eagleopticsvids]

Thanks for watching! With the naked eye you can see a few feet, you can see a mile away, you can see the moon which is thousands and thousands of miles away. When you add the magnification from a binocular you are going to see 8x or 10x more than the naked eye. Ultimately, when you look at distance and magnification it's better to rephrase the question to what you want to see at a certain distance. For example, if you are trying to identify a bird that's 100 yards away with your 8x42 binocular you should have no problem! If you are trying to identify that same bird at 1 mile away you might have a hard time. If we can help with anything else please let us know! Thanks,
