My previous articles on choosing birding binoculars (under $500 here<\/a><\/b>, and under $200 here<\/a> <\/b>and then best at any price here<\/a><\/b>) were about outdoor use. <\/div>\n
They concerned themselves with brightness in the woods or early morning overcast. They worried about ruggedness and waterproofing. They demanded wide field of view for finding birds easily in the sky or tree canopy. And they needed the very best optics available for the best most color-accurate view.<\/div>\n
Binoculars exclusively for backyard bird watching require only a sharp bright view in normal daylight. Many people also want easy close-focus ability to observe birds at window feeders or to see hummingbirds nearby at feeders on the porch or eaves. <\/b><\/div>\n
These binoculars will probably spend most of their time sitting on your window sill waiting for an interesting bird to appear at your feeder.<\/div>\n
 <\/div>\n
 <\/div>\n

 <\/div>\n
This is actually a little bit harder for me to write. I’ve always been concerned with finding birds in more challenging outdoor circumstances.<\/div>\n
Birds at feeders are generally fairly near. So you don’t need extra-strong magnification.<\/div>\n
Birds return all day, so binoculars don’t have to be super bright at dawn and dusk. <\/div>\n
Many times the binoculars will be used from inside the house. And even if used outside, if it rains, bird watchers will take the binoculars indoors. Making binoculars waterproof is expensive. If a cheaper pair of binoculars say they are waterproof, then they might have skimped on the optics quality.<\/div>\n
This also means that I will look at both porro prism and roof prism designs. Rugged roof prism designs are often better for more expensive binoculars where waterproofing is needed. These have more expensive glass and prisms. But the porro prism design is easier to manufacture. So at lower prices the quality of binocular is more similar between the two styles.<\/div>\n
For this type of birding you don’t need a rugged armored binocular with large light-gathering lenses. Something smaller and light weight is ample. Some of the compact binoculars, that I usually avoid recommending otherwise, might be good for this purpose. <\/div>\n
There are so very many of these inexpensive binoculars on the market for under $100. How do you get something that’s not a toy?<\/div>\n
Well, since I don’t have this knowledge immediately at my fingertips, I am going to do what you would do. I’m going to Google binoculars under $100 and get a list of all the recommended ones from the websites that pop up.<\/div>\n
Then I am also going to search binoculars, sort by price, and research each one that is listed. For each pair, I will go to the manufacturer’s website to get the exact specifications.<\/div>\n
I know what makes a good bird watching binocular, so I’ll tell you the advantages of the good ones. I’ll tell you which ones you should probably avoid. But, just because I don’t recommend them, it doesn’t mean they might not be right for you.<\/div>\n
Please bear in mind that as time goes on, prices will change so some of the following may not remain at under $100.<\/strong><\/div>\n
These are binoculars for adults.<\/b> I am going to avoid binoculars made only for children. However, if the binoculars fold so the eyepieces can be used closer together for children’s closer set eyes, or farther apart for adults, I’ll note that.<\/div>\n
I’m going to recommend binoculars with close focus under 10 feet and with eye relief of 15 mm or more for eyeglass wearers.<\/b> But I’ll also be looking for good optical quality, water proofing, and light weight, even though these aren’t as essential for backyard bird viewing, perhaps mostly through the window.<\/div>\n
Regardless, binoculars under $100 are NOT really high quality binoculars. The lowest priced binocular for outdoor bird watching that I recommend is the Celestron Nature DX ED 8×42<\/a><\/b>. It retails for about $175. If you can afford that, please purchase those instead. You won’t be sorry. Really excellent quality binoculars sell for over $2000, for comparison.<\/div>\n

Fortunately, for occasional use to watch birds at your feeder, or for a pair of binoculars for an outing, you can find decent binoculars for under 100 dollars.<\/div>\n

<\/span>Choosing binoculars by size<\/span><\/h2>\n
I’m going to ask you to stick with bird watching binoculars with a magnification of 7 to 10 power (7x to 10x). Frankly, 7x or 8x is ideal for bird watching binoculars<\/b>.<\/div>\n
 <\/div>\n
Binoculars are often called by their magnification and the size of the large objective lens. These two numbers are referred to as the binocular’s size.<\/b><\/div>\n
 <\/div>\n
A binocular of 7×35 (say, “7 by 35”)<\/b> magnifies 7 times. That means that an object through these binoculars 70 feet away, will look as it would if it was only 10 feet away without binoculars. It makes things look 7 times bigger or 7 times closer. A 10×42 binocular magnifies 10 times.<\/div>\n
 <\/div>\n
The 35 part is the diameter of the objective lens in millimeters.<\/b> 35 mm is about 1.4 inches across. 50 mm is almost 2 inches. That’s the lens on the “big end” of the binoculars.<\/div>\n
 <\/div>\n
One useful comparison is that relative brightness can be determined by dividing the lens size by the magnification. This is called the exit pupil<\/b>. Thus, 7×35 binoculars has an exit pupil of 5 mm. The beam of light that comes out of this binocular eyepiece is 5 mm in diameter. And something near 5 mm will give the brightest view, even in dim light.<\/div>\n
 <\/div>\n
A 10×25 binocular has an exit pupil of 2.5 mm. That means that at dusk the view through the binocular will be darker than what your eye sees without a binocular. A 10×50 binocular will have a bright 5 mm exit pupil. You will be able to see fairly well through them at dawn and dusk.<\/div>\n
 <\/div>\n
Full sized binoculars are made with this ideal exit pupil: 7×35, 8×40, 10×50, 8×42 (5.25 mm), 10×42 (4.2 mm).<\/div>\n
 <\/div>\n
Compact binoculars have smaller objective lenses. In daylight they are fine. In dim light they are even dimmer. 8×21 and 8×25 are typical sizes. This is an exit pupil of 2.6 mm and 3.125 mm.<\/div>\n
 <\/div>\n
Mid-sized binoculars have objective lenses of about 30 mm, so 8×30 has a 3.75 mm exit pupil.<\/div>\n
 <\/div>\n
Good backyard birding binoculars under $100 can be full sized or compact.<\/div>\n
 <\/div>\n
NOTE: I don’t want to confuse. So in the following reviews I’m only going to provide a link to Amazon if I recommend the binocular. I want to list as many as possible that other websites recommend, so you know I have considered them.<\/b><\/div>\n

<\/span>Very high magnification binoculars<\/span><\/span><\/h2>\n
More magnification isn’t necessarily better. Especially with low-priced binoculars.<\/div>\n
 <\/div>\n
There are several binoculars recommended on some websites of 15x, 20x, or even 25x magnification. You can’t hold these still in your hand. The view shakes because of tiny movements in your hand muscles. They need to be used on a tripod.<\/div>\n
 <\/div>\n
Frankly, it is hard to make good lenses that magnify that large anyway. If they are under $100 they can’t be very good binoculars.<\/div>\n
 <\/div>\n
If you have a beach house with binoculars mounted on a tripod to look out to sea, then a 15x binocular might be okay. But, then I’d recommend spending a couple hundred dollars and get something better.<\/div>\n
 <\/div>\n
For backyard bird watching binoculars, you may wish to avoid the following<\/b>:<\/div>\n
 <\/div>\n
Bushnell Powerview Wide Angle 20×50<\/b><\/div>\n
Celestron SkyMaster Giant 15×70<\/b><\/div>\n
Celestron SkyMaster 25×70<\/b><\/div>\n
 <\/div>\n
These are huge astronomical binoculars<\/b> for star viewing. They are not suitable<\/b> for watching birds at your feeder.<\/div>\n

<\/span>12x binoculars<\/span><\/span><\/h2>\n
Normally, I would tell you to avoid these, too. They are just too much magnification.<\/div>\n
 <\/div>\n
Hand shake is a problem.<\/div>\n
 <\/div>\n
But also, the field of view is narrow so that they are like looking through a straw.<\/div>\n
 <\/div>\n
Also, large magnification binoculars are generally poor for eyeglass wearers. The spec is called eye relief. It tells you how far back your eyes should be from the binocular lenses. If you wear eyeglasses while looking through binoculars you want at least 15 millimeters of eye relief. More is better, up to 19 or 20 mm.<\/div>\n
 <\/div>\n
Why then do I bother showing these? <\/div>\n
 <\/div>\n
There seem to be many low priced binoculars at this magnification. Rather, what I have found is that there is likely one Chinese manufacturer labeling a single binocular for other brands. <\/div>\n
 <\/div>\n
They have smart phone adapters and their advertising says for adults and kids, and waterproof (they’re not). It also says “low light night vision” or something similar. They tout their large 18 mm ocular lenses, which really are rather small. They also offer 10x and 8x binoculars.<\/div>\n
 <\/div>\n
Please note that there aren’t any expensive birding binoculars at this high magnification. They are all 8x and 10x. That should tell you that 12x isn’t desirable for bird watching binoculars.<\/div>\n
 <\/div>\n
But maybe they’ll be a surprise in here…<\/div>\n

This compact binocular will have a very dim view. They are suitable for feeder birds only in bright sunlight. <\/div>\n
 <\/div>\n
It will be hard to hold these steady because of the high magnification. Field of view is 273 feet @ 1000 yards, very narrow, like looking through a straw, which is not good. Close focus is only 16.4 feet, so poor for using to view hummingbird feeder on eaves or window bird feeder. <\/div>\n
 <\/div>\n
Again, they say waterproof, but you cannot submerge them or wash them in running water in the sink. Not recommended.<\/div>\n<\/div>\n
 <\/div>\n
Well, with what I’ve seen with these, I can safely say to stay away from 12x binoculars for backyard bird watching.<\/div>\n

<\/span>Big heavy 50 mm binoculars<\/span><\/span><\/h2>\n
These are probably better for hunting binoculars and spotting distant wildlife. They give bright view in dim pre-daylight conditions. The large objective lenses of 50 mm will make them heavy and cumbersome. <\/div>\n
 <\/div>\n
It is hard for these binoculars to focus closely on window-mounted bird feeders, or hummingbird feeders hung on your eaves. Probably not the right binocular for backyard bird watching.<\/b><\/div>\n

<\/span>Wrapping Up<\/span><\/h2>\n
There you have it, the results of my research. <\/div>\n
 <\/div>\n
Now, if anybody asks, I will recommend the Bushnell NatureView 8×42 <\/b>as the best binocular under $100 for backyard bird watching.<\/div>\n
 <\/div>\n
If someone wants the cheapest binocular that still is decent for looking out the window at the bird feeder, then the SkyGenius 8×42<\/b> is the one for them.<\/div>\n
 <\/div>\n
\n
And, if someone wants a small, lightweight binocular for observing birds at the feeder, then the compact Vortex Vanquish 8×26<\/b> is the one they want.<\/div>\n
