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 partnered with 42mm objective lenses is the classic bird watching binocular, it is well suited to nature viewing or as a general purpose model. This model gives high clarity, a wide field of view and a natural well balanced image.
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 true colour rendition is required.
The traditional porro prism design 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 in excess of its price point.
