Focus Optimum 8x42 VHG ED – binoculars are binoculars for birdwatching, outdoor observation and travel.
Magnification is 8× and the objective diameter is 42 mm. Magnification helps you study distant subjects, while the size of the objective lenses contributes to the instrument’s light-gathering ability. Choose magnification to suit your use: higher magnification also makes hand movement more noticeable in the image.
The field of view is 140 metres at 1,000 metres. This describes the width you can see and is useful when comparing models for following moving wildlife or scanning a landscape.
Close focus is 2 metres, the shortest distance at which the image can be brought into focus. This matters if you also want to observe subjects nearby.
The model uses low-dispersion ED glass. This helps reduce colour fringing around high-contrast edges, such as branches against a bright sky. It is a useful feature to compare when observing fine detail and subtle colour differences in birds.
The instrument is waterproof according to the manufacturer’s specification, a practical feature for outdoor use in rain and damp conditions. Use lens caps and a case during transport, and clean the optics with a suitable lens cloth.
