Having the best binoculars for birdwatching is vital to appreciate a full view of birds and their behaviors. A pair of quality birdwatching binoculars can help you have a memorable experience while enjoying your hobby.
Understanding Binocular Specifications
Before you buy binoculars, it's essential to understand common specifications to know which pair will be the best to have for birdwatching.
Prism Type and Coatings
Roof prism binoculars can be bulky and do not reflect light like porro prisms. Porro prisms often yield brighter views and are more lightweight in comparison. Also, note the lens coatings. Anti-reflection lenses are coated to the surface of the lens, while phase-correction coatings are on the prisms inside the binoculars.
Magnification and Field of View
Field of view is the image you see through your binoculars, while magnification shows how large and bright the image is. When you see numbers like "8x42", eight refers to the magnification power, and 42 is the width of the objective lens at the front of the binoculars.
As you magnify the target image through your binoculars, you will see less of the details around it, but the target may shrink as you do this. If you're new to birdwatching, a wider field of view is usually best.
Lens Quality and Glass Type
The magnification and objective lens indicate how clearly you can see through your binoculars. The objective lens has a specific diameter size, as mentioned above in the 8x42 example.
Quality birding binoculars feature either BaK-4 or BK7 glass lenses. Manufacturers use these glass types to make prisms, which reflect images and light more effectively. Lens coatings help reflect light off your binoculars so that the images you see are sharper. Your lenses can be fully coated or have a single-layer coating.
Eye Relief and Adjustability
You should be able to adjust the eyecups and the diopter settings of your binoculars for comfortable viewing. If you wear glasses, this is especially vital, as you want eyecups that will fit your eyes without causing discomfort. Look for quality binoculars that have varying eyecup and diopter settings.
Waterproofing and Durability
Your binoculars should be waterproof and fog-resistant to provide the best images in different weather conditions. For example, you may encounter a situation where your binoculars get wet or fog collects on the lenses while observing birding migration patterns. O-rings are placed in binoculars to seal out water and moisture. Opt for waterproof binoculars when navigating your options.
Maintenance and Care Tips
Storage and cleaning go a long way in preserving your binoculars' longevity. Store them in a cool, dry place with low humidity and minimal dust. The best course of action is wrapping them in a plastic bag. Clean your binoculars with the cloth you received when you purchased them or a soft microfiber cloth. Investing in a lens kit is best for protecting your binoculars' life span.
