5. Nikon Aculon T02 8×21
Nikon Aculon T02 8×21
Budget compact binoculars.
A good quality compact birding binoculars for under $100! Nikon has been in the optics field for more than 80 years – they can certainly be trusted. The Nikon Aculon T02 8×21 is for the beginner birder or someone not ready to invest in a Zeiss Terra or Swarovski brand. They are lower-quality glass so don’t expect spectacular brightness & crispness. They are waterproof, fog-proof, and fit into the smallest binocular body I’ve found – 3.4″ x 4.1″.
6. Vortex Vanquish 8×26
Vortex Vanquish 8×26
Another worthy budget compact binoculars.
Although roof prism is preferred for compact binoculars rather than the Porro style, I stand by the Vortex Vanquish 8×25 as a top budget pick. They’re relatively small & light and even though the glass is lower quality than the others and may not render the brightest & crispest image, they’re worth considering for your first pair of binoculars. They’re even waterproof & fog-proof.
7. Nikon ProStaff 8×25 ATB
Nikon ProStaff 8×25 ATB
Another worthy budget compact binoculars.
Similar to the Vortex Vanquish, this is this budget pair is made with a Porro prism (e.g. zigzag tubes) yet is relatively small & light as well as waterproof & fog-proof. Despite the lower field of view (330′) and lower quality lens glass, these are still worthy of consideration, especially for your first pair of binoculars. You can always trade up to the Zeiss Terra or a Swarovski pair down the road.
What’s a Compact Binocular?
While there isn’t a formal industry definition of a compact binocular (also referred to as a pocket binocular), the general idea is they’re smaller and lighter than other binoculars.
So, what size is a compact binocular? Without an industry definition, we can look to binocular manufacturers for guidance. I reviewed the major binocular manufacturers and learned a majority of them append the term “compact” or “pocket” to binoculars with objective lenses smaller than 30mm.
This is logical since the larger the objective lens size, the larger the overall binocular body has to be to contain the lenses. Larger body, larger binoculars.
For the purpose of discussing compact or pocket binoculars, only optics with an objective lens smaller than 30mm are considered.
What to Look For When Purchasing Compact Binoculars for Birding
There are a lot of features available in binoculars these days. It’s hard to know what’s important for birding and what’s not. After cutting through the endless list of features and specifications, I arrived at a shortlist of key features to pay attention to when buying a compact pair of binoculars for birding. They are:
- Magnification & Objective Lens
- Prism Type
- Brightness & Sharpness
- Single Focus Control
- Field of View
- Waterproof & Fog-proof
- Eye Relief
- Warranty
- Compact Size
Magnification & Objective Lens
Every model of binoculars is accompanied by two numbers such as 8×25. The first number represents the magnification (8x) and the second is the size of the Objective Lens (25mm) located at the end of the optics’ tubes.
Magnification
The magnification needs to take that tiny bird and enlarge it to a point where you can see it up close in minute detail. An 8x pair will enlarge the subject 8 times. However, as the magnification increases, a more important aspect of the binocular decreases – the field of view. This is why bigger isn’t better as it relates to binocular magnification. Experts recommend the ideal magnification of compact birding binoculars is between 7x and 9x. The next best choice is 10x.
Look for compact binoculars with a magnification between 7x-9x for general birding.
Objective Lens
The objective lens is located at the end of the tubes and is less than 30mm in diameter for a pair of compact binoculars. The larger the lens the brighter the image will be.
Look for compact binoculars with the largest objective lens size, at least 20mm.
Prism Type
Binoculars are made using either a Porro or roof prism.
The tubes of a Porro prism take a zigzag form so are a bit bulkier but cost less to manufacture. Binoculars with a Porro prism are the old-school-looking binoculars we’re all accustomed to.
Those with a roof prism have straight tubes, tend to be efficiently housed in the binocular body (more compact), tend to be made with better quality glass and cost more to manufacture.
The majority of compact binoculars are roof prisms given that they’re inherently compact with straight tubes. Yet, there are many Porro models available as well.
Look for compact binoculars with a roof prism to minimize the overall size of the optics. Where cost is the primary concern, opt for a Porro prism and put the money toward high-quality lenses.
Brightness & Sharpness
Birding binoculars need to provide a view that is bright, sharp, true to color, and distortion-free so you’re able to see the tiniest of details – even in poor light. These attributes are dependent on the type and quality of the glass used for the lenses and prism as well as the skill of the grinder & polisher. Swarovski Optiks has been manufacturing binoculars since 1949 and is recognized as the Cadillac producer of binoculars states “The better the optics, the less you can see yellow or bluish color fringing”.
Look for compact binoculars made by a reputable manufacturer who’s been in the optics business a long time, and understands and applies grinding and polishing techniques (e.g. Swarovski, Nikon, Vortex, Leica, Bushnell).
The prism material is also key. BAK4 (Barium Crown glass) is considered the Cadillac of materials transmitting light better than the most widely used material, BK7, and the less commonly used SK15.
The prism and lens coatings also play a key part in the resulting view as they work to reduce glare & reflections while increasing light transmission so colors are bright and true.
Look for compact binoculars where the lens is at least multi-coated. Even better is a pair that’s fully multi-coated. On binoculars with a roof prism, check to ensure a “phase-correcting” coating has been applied. Also, avoid binoculars with a zoom feature as they inherently sacrifice brightness for the ability to zoom.
Single Focus Control
The binoculars must be able to focus quickly because birds move fast without warning.
Look for binoculars with a single focus control rather than one control on each tube.
Field of View
The field of view must be wide enough to locate the bird quickly. Earlier, we established that the field of view gets smaller as the magnification increases so the biggest magnification isn’t always better – especially when birds are the subject. Compact binoculars with a magnification range of 7x-9x will generally have a FOV between 220 – 430.
Look for compact binoculars with the largest field of view among the optics meeting the other criteria (e.g. magnification, objective lens). If model A has 8×25 magnification & objective lens plus all the key features and model B has the same numbers and features, select the pair with the highest field of view.
Fog-proof & Waterproof
Fog-proof and waterproof are key features to look for since you’ll be outdoors and should be prepared for whatever Mother Nature wields your way (think humidity and rain showers).
Look for binoculars that are waterproof and fog-proof.
Water-resistant is the next best thing to waterproof as it protects against a light sprinkle of rain but waterproof is best.
Eye Relief
If you wear glasses, pay attention to the amount of eye relief the optics have. Eye relief is a value in millimeters that represents the distance your eyes can be from the eyepiece and still be able to enjoy the full field of view.
Look for binoculars with a minimum eye relief of 15mm.
Warranty
A great warranty protects your investment and reduces the chances of going without the binoculars while you save up for a replacement pair.
With the exception of a budget pair of compact binoculars, look for a warranty with a minimum of one year. The more expensive the binoculars the better the warranty should be such as a 10+ year warranty – better year, a lifetime warranty.
Compact Size
A pair of compact binoculars should be light, either small or folded into a small unit, and easy to slip into a pocket for fast retrieval.
Look for binoculars weighing less than 1 pound, lens diameter of less than 30mm, and less than 5″ long and 5″ wide.
Conclusion
It can be overwhelming to find a compact binocular that’s suitable for birding. I was in the same position which is why I dove into researching and analyzing the top compact binoculars myself.
