Here's short info I sent someone asking for advice on buying binoculars in Hong Kong:
Well, I'm a birder, but rather rarely buy binoculars - my Leicas now maybe 15 years old (not sure)! [Since I wrote this, I lost the binoculars; bought another pair of Leicas - after, happily, receiving insurance.
Best are from Leica, Swarovski, maybe Nikon, Zeiss. Depends partly on "feel" of them when telling between these I think - all should be optically superb, and well built so can last a long time.
