Description:
Let's start with the wrapping system, which has its advantages. Reverse Porro prisms are not much different from the classic porro design (except for inversion), but they combine the advantages of traditional and roof-shaped binoculars. This concerns, first of all, the volume of the image inherent in the first, and the compact dimensions of roof-binoculars. Now you don't have to choose between stereoscopic images and small sizes, you get both.Something for a very reasonable price. The binoculars comes with a bag, a neck strap, protective caps for eyepieces and lenses, and a cleaning cloth.
The diameter of the objective lens allows it to pass a sufficient amount of light, from which the picture becomes bright and saturated. This is also affected by the anti-reflection coating of the lenses at each border of contact between glass and air (Fully coated).
The field of view value, which actually indicates the width of the view that binoculars gives relative to a distance of 1 km, is quite high here. In Barska Colorado 7-21x40 also has a good eye relief millimeter, which affects the darkening of the image at the periphery of the field of view. Good values for twilight factor and aperture, indicating the ability of binoculars to recognize image details in low light and contrast.
Its body has a rubberized coating, binoculars protected from splashes, light impacts and fogging. You can also adjust it for different vision in two eyes.
Due to the gradual increase (from 7 to 21 p.)we can conclude that binoculars Colorado 7-21x40 from Barska is almost universal. It is suitable for observing nature, and for travelers, and for all other purposes.
