I have had several pairs of binoculars for birding in the past, but these surpass the sharpness and comfort of any of them. They are comfortable with the neck strap, and not at all heavy. Color and details of birds near and far are exceptional. I would not hesitate to recommend them to birders of all skill levels.
Kowa BD, an excellent binocular
Robinson from São Paulo, Brazil
This is such an extraordinary binocular and to be honest, it was much more than I expected. I was looking for one from a reliable brand, with good magnification, reasonable field of view, with zero of reflection, comfortable eye relief -because I wear glasses-, improved brightness and high color fidelity, besides not being heavy, suitable for carrying with me in all my getaways to see nature. If you are ok with the price, this is certainly your best choice, but if your budget has many constraints, I would consider the Kowa SV 8x42. Of course, it is not as good as Kowa BD, but it is cheaper option.
Best binoculars in this price range!

Bought these Kowa's to replace a lost pair of beloved Leica Ultra 8x32 (1995; $1500 CDN). Could not justify a replacement pair of Leica's right now ($1800-2300 USD) but still required an excellent pair of binos for work and adventures. I study seabirds so waterproof housing and clear, crisp optics are needed to detect subtle plumage differences, sometimes from boats, and often in poor light. I tested all brands in my price range $500-1200 (Nikon, Pentax, Bushnell, Vortex, Zeiss, etc.) and these Kowa's were the best 8x42's for price and craftsmanship. These Kowa's have bright, sharp optics and easy focus adjustments, even with gloves on. Accustomed to the handcrafted lenses from Leica (thus, clear focus right to the edges), the Kowa's were the only binoculars $500-800 that I tested that came close to this precision. The Kowa's are light, and the neck strap that comes with it is very comfortable - neoprene, about 5 cm wide, with the inside as "smoothskin" so keeps a good grip on the collar. These binos come with a durable soft case, and lens caps for both top and bottom. The top lens cover is one piece and attaches to the left side through the strap. The right side has a slot but it doesn't stay on the strap very well, so I don't use attach it. The bottom ones aren't secured to the binos so I've left them in the box (they have a little slot for attaching to something). The eye cups have multiple elevations (4 stops), so good for adjustments with/without eyeglasses or sunglasses. The only thing I miss from the Leica design is the soft case being attached to the binoculars through the neck strap, thus no chance of putting it down and leaving it behind. I highly recommend these binoculars for professional birders, and am completely happy with them. They are excellent value and top quality.
