Binoculars for Bird Watching: How to Choose in Australia

The main binoculars buying guide explains how to read the figures printed on a pair and how to use binoculars with glasses. This page covers what matters most when the target is a bird.

• Magnification and steadiness: 8x gives a wider field of view (how much of the scene you see at once) and a steadier image, so it is easier to find and follow a moving bird. 10x shows more detail, but it magnifies every wobble of your hands too. A wide view matters because birds are often fast and distant.^[2],[3]
• Brightness: the exit pupil is the small circle of light that leaves the eyepiece, and you find its size by dividing the front lens width by the magnification. A bigger one generally gives a brighter image at dawn and dusk. An 8x42 works out at 5.25 mm and a 10x42 at 4.2 mm.^[2]
• Lens size and handling: smaller front lenses make a lighter, more compact pair that is easier to carry and hold. Pocket models, with lenses of about 25 mm, are the smallest. They can be fiddly to adjust, with small eyecups and focus wheels, and the narrow beam of light can feel like tunnel vision.^[4],[5]
• Wearing glasses: eye relief is the distance from the eyepiece lens to the point where your eye sees the full view. Folding the eyecups down lets the lenses sit closer to your eyes, which makes up for the extra distance glasses add.^[6],[7]
• Wet conditions: some binoculars are listed by Australian retailers as waterproof (up to 1 m for 10 minutes) and fog proof. Check the stated rating for any pair you consider.^[8],[9]
• Warranty: consumer guarantees under Australian Consumer Law are automatic and can't be taken away, so they apply whatever a warranty says. A warranty is an extra promise a business can choose to make on top, and it can't replace, change or take away those basic rights, which can last longer than the warranty. If a product is not safe, durable and free from defects, you can claim a repair, replacement or refund, so check the current rules with the ACCC.^[10],[11]

BirdLife Australia members can ask their retailer for a member discount. Some BirdLife branches have existing arrangements with a local dealer.^[12]
