The Visionary HD series is designed with the idea of coupling magnifications to their optimum front lens size to give exceptional clarity and brightness.
The 8x magnification coupled with 56mm objective lenses is well suited for birds and nature viewing, however this models strong point is its use as a low light instrument e.g. for astronomy or security applications, it has been used widely on ships bridges.
High Resolution BAK4 prisms ensure a brighter image throughout the range of magnifications by maximising light transmission. Efficient use of the light gathered is particularly important at high magnifications where images appear darker or for applications were colour rendition is important.
The traditional porro prism designed gives higher quality images when compared to roof prism or compact (reverse) porro prism designs in the same price range.
Long eye relief makes these binoculars ideal for spectacle wearers. It enables users wearing spectacles to view the entire field of view as the binocular image is projected further out of the exit pupil.
The quality of the image produced by these binoculars is such that you could use it for applications that would normally require a higher magnification and it compares favourably to binoculars well above it’s price point.
