The large 56mm objective lenses help capture more light and the moderate 8x magnification contributes to the very large 7mm exit pupil on these which ensures that your eyes are being supplied with enough light even in very low light when your pupils are dilated to their maximum size.
Thus it is the specific 8x56 configuration of these Kowa Prominar XD binoculars, along with their very high-quality fully multi-coated optical components and coatings that make this model, in particular, an extremely good low light performer.
This characteristic makes them an ideal choice for the birder, hunter or general wildlife observer who often finds themselves out at twilight or who operate in thick forests and who either don’t mind carrying a slightly larger, heavier instrument or who perhaps observe from a static position like a hide or viewing platform.
Astronomers will also appreciate these binoculars for their low light performance and whilst the 8x magnification does not have the reach of higher powered instruments, they are great for observing the moon and their wide field of view means that you are better able to observe complete constellations and star clusters.
The 23mm of eye relief is excellent and along with their click-stop adjustable twist-up eyecups means they are an ideal binocular for the eyeglass wearer.
BD XD Prominar series of binoculars by Kowa manufacturer offers compact-size, all-rounders and nighttime binoculars for long distance observations. Perfect for hunters, birdwatchers, hikers, travelers, safari etc. Tthe nighttime binoculars with 56mm lens diameter are suitable for astronomy applications. All the models are built out of rugged and durable materials, special Prominar XD lenses and layers of C3 high-quality optical coatings. Wider field of view and stunning close focusing distance that these compact and all-round models provide, are able to satisfy the not only beginners but also the demanding users. Great balance and full protection of these BD series are also very important features.
The compact size model in this BD series is made out of Aluminum body and all-rounders are made out of lightweight Magnesium chassis that makes them less fatiguing. Nighttime models are made out of Polycarbonate body, the lightest material that significantly helps to take the weight off your shoulders. All BD HD Prominar binoculars are enclosed in rubber armour to make construction shock-proof and impervious to water and dust. Completely sealed body is purged with nitrogen gas that prevents the formation of condensation due to temperature changes that especially occur during the sunrise or sunset. These series offer great ergonomics due to their stylish and practical design and perfect weight distribution and balance. All models are equipped with twistable eyecups that offer ideal eye-relief even for those wearing eye glasses. Focusing is adjusted with a very grippy silver central focusing wheel diopter that is integrated onto central wheel (56 mm models) or beside the right eyecup (32 mm and 42 mm models).
BD series is equipped with special PROMINAR XD lenses that enhance brightness and help with extremely razor sharp images due to extra-low dispersion rate that reduces chromatic aberration. C3 coatings that are applied on the glass help with better light transmission, colorful lifelike images and phase correction which delivers a powerful contrast and resolution for stunning view-through. These binoculars provide wider field of view for quicker tracking. All-round and compact models offer extremely generous close focus distance (1.5m) perfect for macro observations. The objects up close will reveal even the smallest details of the birds, insects, etc.
Kowa BD includes extremely comfortable neckstrap for carrying, objective covers and rainguards for protection of the lenses and case for storage.
