Binocular frequently asked questions
Frequently Asked Questions about Binoculars in New Zealand
Our binocular FAQ section is designed to provide clear, helpful answers to assist you in choosing the best binoculars for your needs, whether for birdwatching, hunting, or general outdoor use.

What do the numbers on binoculars mean?
The numbers printed on binoculars indicate their magnification and the diameter of the objective lens. For example, in 8x42 binoculars, "8x" means the object you’re viewing appears 8 times closer than with the naked eye, and "42" refers to the 42mm diameter of the objective lens, which affects how much light enters the binoculars.
What’s the difference between Porro prism and Roof prism binoculars?
Binoculars come in two main designs: Porro-prism and Roof-prism. Roof-prism binoculars have a more compact, straight-barrel design, making them easier to carry, ideal for outdoor activities like birdwatching and hiking. Porro-prism binoculars, with their offset design, are bulkier but generally more affordable. Both types offer similar image quality, though Roof-prism binoculars are typically more popular due to their sleek design.
What are the best binoculars for bird watching in New Zealand?
For birdwatching, binoculars with 8x or 10x magnification are ideal. 8x binoculars offer a wider field of view, making them easier to use for tracking birds and providing a brighter image in lower light conditions, perfect for forested areas or during dawn and dusk. 10x binoculars, on the other hand, are great for long-distance viewing in open spaces like coastal regions but may be harder to hold steady for long periods. Beginners often prefer 8x for a more stable image. Check out our buying guide for bird watching here for more detailed information.
What size binoculars do I need?
The size of your binoculars depends on the diameter of the objective lens. Larger lenses (40mm or more) gather more light, providing brighter, clearer images, especially in low-light conditions. However, they can make the binoculars heavier. For birdwatching, many people opt for 8x42 or 10x42 binoculars, which balance brightness and portability. If portability is key, smaller binoculars like 8x32 may be better suited to your needs.
How do you fix binoculars that won’t focus?
If your binoculars aren’t focusing properly, start by checking the diopter adjustment, which allows you to adjust the focus for individual eyes. Make sure the central focus wheel is functioning smoothly and that nothing is obstructing the lenses. If the focus issue persists, there may be internal damage or alignment problems, and it’s best to take them to a professional for repair.
How much does a good pair of binoculars cost?
The price of binoculars varies depending on features, quality, and brand. A good pair of entry-level binoculars typically costs between $150 and $300. Mid-range binoculars with better optics, waterproofing, and fog-proofing can cost between $300 and $800. High-end models with premium features such as ED glass and advanced coatings can cost over $1,000.
What binoculars do hunters use, and what’s a good magnification for hunting?
Most hunters prefer 8x42 or 10x42 binoculars. These models provide a good balance between magnification and brightness. 8x binoculars are great for scanning wide areas in lower light conditions, such as forests or at dawn, while 10x binoculars offer higher magnification for long-distance spotting in open fields or mountainous terrain. Both sizes are popular because they offer enough zoom without being too difficult to hold steady. Take a read of our buying guide for hunting binoculars here.
What kind of binoculars are best for hunting?
For hunting, choose binoculars that are rugged, waterproof, and fog-proof. 8x42 and 10x42 binoculars are commonly recommended, as they provide enough magnification to spot game at a distance while being light enough to carry in the field. Look for models with good low-light performance, especially if you hunt during dawn or dusk when animals are more active. Take a read of our buying guide for hunting binoculars here.
How do I choose binoculars for hunting?
When choosing hunting binoculars, consider factors such as magnification, objective lens size, field of view, and durability. 8x42 binoculars are ideal for close- to mid-range hunting, while 10x42 binoculars offer greater magnification for long-range spotting. Make sure they are waterproof and fog-proof, and opt for models with durable rubber armour for better grip and protection. Take a read of our buying guide for hunting binoculars here.
Can binoculars be repaired?
Yes, binoculars can often be repaired, especially if the issue is related to the focus mechanism, misaligned optics, or external damage. Many manufacturers offer repair services, but it’s important to get binoculars repaired by professionals to avoid further damage, particularly if they are waterproof or fog-proof models.
What binoculars are good for sporting events?
For sporting events, compact or midsize binoculars with a magnification of 8x or 10x work well. Look for models that offer a wide field of view, as this will allow you to track fast-moving action easily. Lightweight binoculars such as 8x32 are also a good choice if you want something easy to carry and hold during long events.
What are binoculars used for in hunting?
Binoculars are essential for spotting and tracking game from a distance, helping hunters to identify animals without getting too close. They’re also used to scan large areas of terrain and to observe game movement without startling them. Binoculars with good low-light performance are particularly useful for early morning or late evening hunts.
Can I take my binoculars apart to clean them?
No, it’s not recommended to take binoculars apart, as this can compromise their waterproofing and fog-proofing features. Modern binoculars are sealed and filled with nitrogen gas to prevent internal fogging. If there’s dirt or moisture inside, it's best to have them professionally cleaned.
Do I need to use a tripod with my binoculars?
Most binoculars do not require a tripod for general use. However, for high-powered binoculars (10x or more) or for specific activities like stargazing, a tripod can help stabilise the view, reducing image shake and improving the overall experience.
How do I mount binoculars to a tripod?
To mount binoculars to a tripod, you will need an L-shaped adapter. This adapter securely holds the binoculars to the tripod, providing a steady image. Using a tripod is especially useful for high-magnification binoculars or extended viewing sessions, such as birdwatching from a stationary position or viewing stars.
What is diopter adjustment on binoculars?
The diopter adjustment allows you to fine-tune the focus for each eye individually, compensating for any differences in vision between your eyes. This ensures a sharper, clearer image.
How do I use the diopter adjustment on my binoculars?
To set the diopter adjustment, first, set it to zero. Cover the lens on the side with the diopter adjustment and use the main focus wheel to adjust the image for your other eye. Then switch lenses, and fine-tune the diopter adjustment until the image is sharp.
What is the field of view, and why is it important?
Field of view refers to the width of the area you can see through the binoculars at a distance. A wider field of view makes it easier to locate and track moving objects, such as birds in flight, and is particularly important in birdwatching or wildlife observation.
What is the exit pupil, and why does it matter?
Exit pupil is the size of the beam of light that reaches your eyes through the binoculars. It is calculated by dividing the diameter of the objective lens by the magnification. A higher exit pupil number is important for low-light conditions, such as dawn or dusk, as it provides a brighter image. For example, binoculars with a 42mm objective lens and 8x magnification will have an exit pupil of 5.25mm, which is ideal for viewing in dim lighting conditions. A larger exit pupil makes it easier to see brighter images, especially in low-light environments or for activities like birdwatching or stargazing.
