Best for
This is a grab-and-go binocular for people who want genuine Leica optics without the bulk. The folding compact body suits travel, city breaks, hiking and general days out, while the 10x magnification works well at the theatre or opera, at sporting events and concerts, and for casual wildlife and landscape spotting. It is a natural fit for anyone who wants a capable binocular kept permanently in a pocket or bag, though the higher 10x power means a steady hand helps when viewing distant subjects.
Frequently asked questions
Is the Leica Trinovid 10x25 BCA waterproof?
No. Leica rates it as splash-proof and it is not nitrogen-filled, so it will shrug off light rain and spray but should not be submerged or exposed to heavy water.
Will it work if I wear glasses?
Yes. It offers 14.6mm of eye relief with extendable eyecups, so spectacle wearers can fold the cups down to take in the full field of view.
How compact is it really?
Very. It folds flat on its central hinge to about 92 x 110 x 37mm and weighs around 255g, so it slips easily into a jacket pocket or small bag.
What is the closest focusing distance?
About 5m, which is fine for general viewing though not close enough for detailed insect study.
