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!

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

[@TheGame-km5ur]

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.

[@MRGOOPY123]

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

[@BeingDengineer]

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

[@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!

[@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?

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

[@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.

im using a bushnell pair. 12x50.. but i go hunting in long long feilds.. can u suggest something with more zooming power?

[@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?

[@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 ?

[@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 ?

[@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?

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.

[@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]

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.

[@sidi143]

Thanks for this informative video.I would like to knw ur opinioun abt Nikon 10x50 Action series Binocular.

[@marioarias6413]

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

[@googoogolly3943]

Thankyou, newbie here in the UK. Very helpful and well put together tutorial.

[@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

[@abhishekpratapsingh1031]

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

[@raeesauxbeat8807]

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

[@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.

[@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.

[@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!

[@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.

[@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?

[@asseenontvstuff]

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

[@AmienPhillips]

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

[@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.

[@mambaman2007]

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

[@petesessa2041]

I needed to up my game as a home inspector. This video was very helpful. I guess I still don't know what's best for looking at roofs that I can't climb on. 8 or 10? Any thoughts? Thanks.

[@michaelcreamer9317]

Pete Sessa 8

[@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.

[@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.

[@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?

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

[@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.

[@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?

[@jonathanmoore5709]

what is the wheel in the middle of binoculars for

[@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.

[@GetRhythm2011]

What great and very useful information. Thank you to both of you. Much obliged. :) I am looking for a nice compact binocular for my wife, as we often are out and about seeing moose, elk, and all kinds of critters, but also go to events such as sheep dog trials where clarity with minimal shake at such a far distance is very important. Any recommendation for a good all around pair of compact binocs would be GREATLY appreciated. Thanks again! :) Chuck

[@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!

[@yourtube20061]

@eagleopticsvids thanks for the prompt reply. haha, why do u say it shd be avoided ? it would most probably be fake ?

[@Calliber84]

I always tried to research what those numbers meant. now I know. thanks guys so much

WOW where are you filming this?! The scenery is BEAUTIFUL!

[@eagleopticsvids]

+2Palu Much? This was filmed at Pope Farm Park, off of Old Sauk Road here in Wisconsin. Glad you enjoyed the video! Thanks!

[@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.

[@petenicezz]

Hello, im looking to buy my first binocular for night sky gazing especially planets but there so many binoculars out there and dont know which to buy. Any suggestions? Thx.

[@mayellee]

[@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

[@guillermomaura4447]

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

[@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.

[@mixup65]

Hi can you suggest me a binocular which full fill my demand. I want a binocular for viewing sky, moon if possible then planets too. It must have HD quality viewing with night vision also it must be very powerful to show objects around me. Suggest me best binocular please or give me list of binoculars you think that are best in world.

[@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.

[@badalbadal5904]

Can u recommend something please.

[@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!

[@Bear_83]

when light travels into a binocular it inverts it and then flips it backwards but when we use it why do we not see it inverted backwards but normal?

[@eagleopticsvids]

So glad you enjoyed it! Thanks for watching!

[@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.

[@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

[@noneyanoney4633]

I was hoping for a 10 X 100mm binocular but I'm guessing that isn't possible for some reason due to the optics involved.

[@lawrancewilson8751]

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

[@TechEntertainFun]

sir. 30*60 is more powerful or 8*21

[@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.

[@philthebarber]

that was an excellent review. want more from you guys. will look. thanks.

[@philthebarber]

whats the retail? seeing them on ebay for 200$. that a fair price?

[@philthebarber]

would like the compact size. would it take away from quality if the unit is smaller?

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.

Informative video. The magnification comparison isn't close to accurate, though. The 8x demonstration shows just slightly more than 2x compared to the naked eye. And in the field of view comparison 10x is around 2x larger than 8x, while 10x in practice is 1,25x larger image scale than 8x.
