Buying Binoculars
Buying your first pair of binoculars can feel overwhelming. Here are the key things to look for so you can choose binoculars that feel right for birdwatching.
Magnification
What is it?
Magnification tells you how much closer binoculars make a bird appear.
It’s the first number in the specs. For example:
8×42 means the image appears eight times closer
10×50 means ten times closer
What to choose?
For most birdwatchers, 8× or 10× works well.
Choose 8× if you want something lighter and steadier. Choose 10× if you’re happy with a bit more weight for extra detail.
Object Lens Diameter
What is it?
This is the size of the front lens, measured in millimetres. It’s the second number in the specs e.g. 8×42 has a 42 mm objective lens
Why it matters
Smaller lenses (around 42 mm) - Lighter to carry, slightly less bright in low light
Larger lenses (around 50 mm) - Brighter in dim conditions like early morning or dusk, but heavier
What to choose
You can’t go wrong with 42 mm. Many birders start here for a good balance of weight and brightness. Choose 50 mm if you birdwatch a lot in low light and don’t mind extra weight.
Other things
Budget - You don’t need to spend a fortune. Mid-range binoculars offer excellent quality for beginners.
Comfort - Look for a comfortable grip and adjustable eyecups, especially if you wear glasses.
Waterproofing - Useful for birdwatching in changeable weather or near water.
Lens coating - Terms like fully multi-coated or anti-reflective help ensure a brighter, clearer image.
Brand reputation - Reliable brands include NOCS, Canon, Celestron, Leica, Nikon, Swarovski and Zeiss.
Try before you buy
If you can, visit a binoculars shop and try a few pairs. Notice how they feel in your hands, how easy they are to focus, and whether the weight feels comfortable after a minute or two. The best binoculars are the ones you’ll actually enjoy using.
