Focus Activa 8x21 – compact binoculars are compact binoculars for walks, outdoor trips and travel.
Magnification is 8× and the objective diameter is 21 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 122 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 5 metres, the shortest distance at which the image can be brought into focus. This matters if you also want to observe subjects nearby.
