Binoculars 20x50 Bassell Green
The Bassell 20x50 binoculars are a classic, fully-coated 20x model with BK-7 Porro glass prisms and a tough, impact-resistant rubber-coated body for better grip and protection against dirt and moisture.
Bassell 20x50 binoculars have central focusing. The focus wheel is large, with a comfortable notch. The stroke is smooth and short, from lock to lock the drum makes one revolution. Provided in the design and diopter adjustment.
The field of view of the binoculars is 137 meters at 1000 meters.Rov. Fairly large lenses provide optimal light output and good color reproduction. Negative aberrations are negligible.
A rather decent weight (850 grams) does not make hand-held observation particularly comfortable, so Bassell 20x50 binoculars have a socket for a tripod L-adapter.
