The best binoculars in 2021: binoculars for wildlife, nature and astronomy

The best binoculars for astronomy are different to what you would choose for bird-watching, hiking or horse racing. Sometimes you need as much magnification as possible for wildlife, sometimes you need maximum light-gathering power for the night sky, and sometimes you need binoculars small enough and light enough to fit in a jacket pocket. This guide explains what to look for and which binos we think are the best.

If you are just starting out or your budget is limited, you won't want to spend a fortune on a premium pair of binoculars. On the other hand, if it's a lifetime hobby or your profession, you'll probably want the best you can reasonably get. With that in mind, we've split our guide into 'affordable' and 'premium' sections.

How to choose the best binoculars for you

In every binocular's specifications there are two figures that will tell you exactly what you need to know to help you find the right binocular for you – the magnification and the size of the lenses. 

Typically, every binocular's name will include something like '7x50' or '8x30'. The first figure is the magnification, the second figure is the size of the lenses. A higher magnification sounds great, but this will limit your field of view and make it harder to keep the binoculars steady. Larger lenses make the image brighter and clearer in low light, but they also make binoculars heavier and harder to hand-hold for any length of time.

So for any given hobby or subject, there's typically a combination of magnification and lens size which works best.

Best binoculars for astronomy: The binocular size for stargazing is 7x50 or thereabouts. 7x works perfectly for astronomy, as a good compromise between angle of view and magnification, and 50mm lenses are larger than usual and will help you see lower magnitude stars and faint objects like nebulae.

Best binoculars for horse racing and other sports: You won't need to look for large lenses, as you'll mostly be using them in daylight. So, a typical spec might be 8x30, as the 8x magnification will be about right for trackside or grandstand viewing, while the 30mm lenses will be light enough to make holding the binoculars less tiring. 

Best binoculars for nature: For this it's a good idea to go for a higher magnification but not necessarily such big objective lenses – smaller lenses will make the binoculars less tiring to hold. Steiner's lightweight 2212 10x 26mm Safari UltraSharp Binoculars take this to the extreme. The alternative is to use a mounting adaptor to fix the binoculars to a tripod, or swap to a higher-magnification spotting scope.

Other features to look our for are anti-fogging and weatherproofing and, if your budget will stretch that far, image stabilization. Yes, you can get image stabilization in binoculars, too!

In the list below we've picked out some favorite models from current binocular ranges, but do note that other size variations are available from resellers, so you can choose other combinations of magnification and size.

The best binoculars in 2021

Affordable binoculars

1. Nikon Prostaff 3S 10x42

Rubber-armored binoculars that are great value

Magnification: 10x | Objective diameter: 42mm | Field of view at 1000m: 122 meters /400ft | Closest focusing distance: 3 metres/ 10ft | Eye relief: 15.7mm | Weight: 575g | Dimensions: 150x130x52mm

Big-name brand at a modest price
Rugged rubber armor construction
O-ring sealed
Not premium optical quality

A previous Red Dot design award winner, this mid-range Nikon model with a rubber armored, non-slip construction comes in either 8x42 or 10x42 options, and weighing just 575g despite its robust build, won’t give you aching wrists. It further features a highly reflective silver alloy mirror coating on the surface of its prism lenses to provide what’s claimed to be a bright and clear view, while a long eye relief enables comfortable viewing, particularly for those who wear glasses. O-ring sealed and nitrogen filled, this waterproofed pair will also deliver a fog-proof performance when used outdoors. Simply put, this is a good all-round option that delivers plenty of visual ‘bang’ for your buck. The very best binoculars cost a great deal more than this, of course, so you have to decide what's a reasonable expense.

2. Celestron Outland X 8x42

Best value binoculars that deliver a lot for the money

Magnification: 8x | Objective diameter: 42mm | Field of view at 1000m: 118 metres (357 ft at 1000yds) | Closest focusing distance: 3.96 metres/ 13.1ft | Eye relief: 18mm | Weight: 624g / 22 oz | Dimensions: 146x126x53mm

Versatile and well suited to wildlife
Sturdy polycarbonate housing
Available in green or black
Neither small nor light

Something of a bargain, this pair of Celestron BaK-4 prism binos boasts 8x magnification and multi coated optics to prevent anything from marring your view. This isn't the only size – you can get these Outland X binoculars in other magnifications and sizes too. Suitable for outdoor use by birders and wildlife watchers, thanks not only to said magnification but also a sturdy polycarbonate build and waterproofing, the decent-sized 42mm objective lenses on offer here will aid light gathering, making these binoculars suitable for use in low light as well as regular daylight. A large smooth-feel focus wheel aids operation and a long 18mm eye relief delivers viewing comfort. Capable of being tripod mounted if desired, a strap, lens cloth and carry case comes as standard, plus a limited lifetime warranty.

3. Kowa YF30-6 / YF30-6 II (green)

Tough outdoor binoculars with a dash of style thrown in

Magnification: 6x | Objective diameter: 30mm | Field of view at 1000m: 140 metres | Closest focusing distance: 5 metres | Eye relief: 20mm | Weight: 470g | Dimensions: 160x114x48mm

Very wide viewing field
Thick rubber armor
A love-or-hate modern design

Well suited to bad weather, as they’re not only waterproof, but nitrogen filled with it – Kowa’s YF30 series of binos offer 6x or 8x magnifications with a 30mm objective lens diameter. They offer portability in spades, each weighing less than 500g. For the sake of variety, we’ve opted for the 6x30 option here, which boasts an extremely wide viewing field of 140m at 1000m – so you’ll be able to observe a great deal without actually adjusting their position. The coated lenses are said to offer good resistance to dirt, too, making these binoculars easy to maintain. This is a modern interpretation of the classic porro prism optical configuration, with thick rubber armour and moulded soft contours.

4. Celestron SkyMaster Pro 20x80

The best binoculars for astronomy and star-gazing

Magnification: 20x | Objective diameter: 80mm | Field of view at 1000m: 56 metres | Closest focusing distance: 20.2 metres | Eye relief: 15.5mm | Weight: 2.45kg | Dimensions: 330.2x241.3x101.6mm

High magnification and large lenses
Rugged rubber armour
Large lenses mean a big pair of binos
Better on a tripod

To shoot for the stars, you obviously need a pair of binoculars with a high magnification factor – as well as ones with excellent light gathering abilities. We get both here with the splendidly named ‘SkyMaster’, ensuring this affordable pair is tailor-made for amateur astronomers, allowing for use at dusk, dawn and night. Multi coated lenses combine with BaK-4 prisms to allow for increased light transmission and therefore high contrast images with bags of detail. Stargazers will also benefit from the fact that this option can be tripod mounted, while it also has its own centre support rod for increased stability. A polycarbonate and aluminum build provides both robustness and portability, while we also get a product that is waterproofed and fog-proofed with it, which is especially useful on cold winter nights.

5. Opticron Savanna WP 6x30

The best binoculars for kids – lightweight, simple to use and affordable

Magnification: 6x | Objective diameter: 30mm | Field of view at 1000m: 140 metres | Closest focusing distance: 3 metres | Eye relief: 21mm | Weight: 485g | Dimensions:: 116x160x40mm

Compact and light – fit in a sling bag
No eyestrain for kids as young as seven
Not the most powerful binos
Lacks features like anti fogging

The low-cost Opticron Savanna WP 6x30 binoculars are portable, waterproof and contemporary-looking porro prism binoculars, and they’re as suited to youngsters as they are adults. In fact, this range – 'Savanna', rather than 'Savannah' – is said to be usable by children aged 7+ without fear of eyestrain. As well as being compact enough for little hands, they’re relatively lightweight too, at a little under 500g, while offering a relatively wide field of view for curious eyes and minds. The 6x magnification doesn’t make them the most powerful pair of binos on the block, but you can upgrade to the 8x30 model – weighing just a few grams more – for just a little more outlay, which represents something of a bargain in itself.

6. Steiner 2212 10x 26mm Safari UltraSharp Binocular

High magnification in a compact pair of binoculars

Magnification: 10x | Objective diameter: 26mm | Field of view at 1000m: 101m metres / 331ft | Closest focusing distance: 5.6m / 18.5ft | Eye relief: 11mm | Weight: 297g | Dimensions: 120mm in length

Generous 10x optical zoom
Extremely lightweight at just 297g
Optics not top of the class
No IS or tripod connectivity

While the 10x magnification factor of the Steiner 2212 10x 26mm Safari UltraSharp Binoculars is certainly impressive, what also grabs your attention is how light they are, weighing just 297g, but a glance at the specs reveals a lot of this is due to the pretty small 26mm objective lenses. Handling is excellent, however, with an ergonomic grip and intelligently laid-out controls, and optical quality is near top of the range. They're not quite at level of, say, the Canon or Zeiss (see below) binoculars, but at this price they're really nothing to sneeze at. Made with high-contrast optics that deliver an image of exceptional quality, these binoculars represent some of the best value for money on this list.

7. Celestron Nature DX 10x56

Great mid-priced binos for low light conditions

Magnification: 10x | Objective diameter: 56mm | Field of view at 1000m: 105m | Closest focusing distance: 3m | Eye relief: 18.2mm | Weight: 1030g | Dimensions: 167x146x65mm

Nitrogen filled to prevent fogging
Suitable for low light with large 56mm lens
Heavier than many alternatives

There are binoculars from Celestron’s Nature range, with even higher magnification and larger objective lenses, and likewise there are devices that cost less with smaller lenses and less magnification, so we’ve gone for a good value option in the middle that, with a 10x56 spec, ticks our essential boxes and makes for a decent all-rounder, particularly with the facility to focus as near as 3m too. As well as being great in low light, they're suitable for outdoor use, thanks to a durable polycarbonate construction filed with dry nitrogen gas to prevent fogging in cold and wet conditions. Add in multi-coated optics and this is a robust, well-specified pair of binos suitable for everyone from beginners to intermediate users.

8. Olympus 10x42 PRO

The best binoculars for safari – and they are waterproof too

Magnification: 10x | Objective diameter: 42mm | Field of view at 1000m: 108 metres | Closest focusing distance: 1.5 metres | Eye relief: 16mm | Weight: 665g | Dimensions: 131x140x53mm

Compact relatively light and versatile
Waterproofed and nitrogen filled
10x may not be enough for wildlife
Pretty pricey

This bright, sharp and reliable model from the Olympus pro line up (a new 8x42 version is also available) features nano coating for the first time in the range. Olympus is renowned for its optical expertise, so it’s no surprise that we get the same high performance Zuiko optics that it deploys with its camera systems. Indeed, the claim here is the binos’ optics offer unprecedented light transmittance for their class. Compact, ergonomically designed and of rugged construction that prevents any ingress from water if submerged at a depth of one metre for five minutes, close up performance is also impressive, with the ability to view subjects as near as 1.5m. Nitrogen filling prevents fogging while the design is slim and simple. An extendable eye relief provides comfort for spectacle wearers, as do a dioptric adjustment ring, flip down lens cap and a new strap mount. A 15-year warranty provides extra peace of mind.

9. Leica Trinovid-HD 10x42

Nice binoculars, and much cheaper than Leica cameras!

Magnification: 10x | Objective diameter: 42mm | Field of view at 1000m: 113 metres | Closest focusing distance: 1.6 metres/ 5.3ft | Eye relief: 15.5mm | Weight: 730g | Dimensions: 117x140x65mm

Full body rubber armor
Outstanding image sharpness
Excellent colour fidelity
Luxury price tag 

Fashioned to survive almost anything, the Leica Trinovid-HD 10x42 binos get our vote for the best binoculars for bird watching right now. And they’re not just good for ‘birders’: in truth, they’re a solid all-round option as well. If you’re looking for a combination of state-of-the-art image performance and a ruggedness that will withstand whatever the outdoors may throw at you, then we recommend Leica’s impact-resistant Trinovid-HD 42 range. Their ergonomic design and steady grip allows for accurate and precise focusing, delivering both razor sharp close-ups of our feathered friends, plus long distance clarity. The performance stays consistent too, whether you’re viewing subjects at first light or at dusk. Good contrast and colour fidelity are key for bird watchers and these binoculars offer that in spades, as well as several choices of model, from Leica Trinovid HD 8x32 to the 10x42 we’ve selected.

10. Nikon Monarch HG 10x30

They are expensive, but amongst the best compact binoculars of all

Magnification: 10x | Objective diameter: 30mm | Field of view at 1000m: 121 metres /362ft | Closest focusing distance: 2 metres/ 6.6ft | Eye relief: 15.2mm | Weight: 450g | Dimensions: 119x126x47mm

Wide angle of view 
Anti-fog magnesium alloy build
You pay a premium for the compact construction

One of the newest premium binoculars on the market comes from Nikon in either 8x30 or – as we’ve selected for our top pick – 10x30 options. The Nikon Monarch HG 10x30 binoculars are not only compact and relatively portable at 450g, the magnesium alloy build has the benefit of being water and fog proofed too. The idea is that these ape the performance of Nikon’s Monarch HG 42mm diameter version, but in a smaller body. Use of extra low dispersion (ED) glass corrects chromatic aberration that can cause colour fringing, while comfort is provided via a soft-to-the-touch neck strap. Both Nikon’s 10x and 8x options are supplied with a semi hard-type case for protection when transporting. A tripod adaptor for each is an optional extra. If you’re looking for the best compact binoculars, this pair from the camera stalwart takes the crown.

11. Zeiss Victory SF 10x42

The best luxury binoculars – if you have thousands to invest

Magnification: 10x | Objective diameter: 42mm | Field of view at 1000m: 360ft * | Closest focusing distance: 5ft | Eye relief: 18mm | Weight: 27.5 oz | Dimensions: 6.8x4.9 inches

Made by the famous optical specialists
Crystal clear performance

Zeiss is synonymous with cutting-edge optical performance, and if you’re looking to luxuriously spend into the thousands to obtain the very best binoculars possible, then check out the Victory line up – said to be the best that Zeiss has to offer. Suitable for pretty much every pursuit, especially the watching of wildlife, the 10x magnification of our pick, the Zeiss Victory SF 10x42, not only brings the faraway up close, but the optical performance has a crystal clarity thanks in part to a seven-lens eyepiece. This particular model is also the most versatile, as well as the most premium, with an evenly balanced weight distribution and ergonomic grip making hand-holding the binos for a prolonged period a pleasure. Zeiss also claims that a large exit pupil measuring over 5mm reveals the details in dark shadows or dim dusk.

12. Canon 10x42L IS WP

The best image-stabilized binoculars...

Magnification: 10x | Objective diameter: 42mm | Field of view at 1000m: 114 metres | Closest focusing distance: 2.5 metres | Eye relief: 16mm | Weight: 1110g | Dimensions: 137x175.8x85.4mm

Steady image stabilized performance
Weather proofed with it
10x magnification and good size optics
Bulkier than non-stabilized binos
Weightier than most at 1,110g

All of Canon’s current range of binoculars have the ‘IS’ suffix in their model name to denote the fact they’re image stabilized. This battery-operated option enables you to get a wobble-free image by just pressing in a button on the binoculars – and the stabilizing effect is both instant and jaw-dropping. From the broad range of Canon IS options available, we've picked the rubber coated Canon 10x42L IS WP model as the best, because – as the name suggests – they’re additionally waterproof, so ideal for an even broader range of long-distance pursuits. Also, Canon’s ‘L’ series is its premium line up, providing a super steady view in the most adverse of conditions. As well as rock-solid stability, these porro prism binoculars sit comfortably in your hand and sport a comfortably long (at 16mm) eye relief, plus a large 4.2mm exit pupil for a bright field of view. They also offer a closest focusing distance that’s closer than most, at just 2.5 metres.
