Description
The optical construction of the Alpina Pro Zoom Binoculars also feature large exit pupils (objective lens) which ensure bright and brilliant images, even under difficult light conditions. The binoculars are hugely versatile, having the ability to zoom into a subject, for better viewing.
Simply focus on the subject through the binoculars and then move the zoom lever position up or down to bring it nearer or further away; the zoom facility really helps with picking out the finer details of the subject. Zoom binoculars are notorious for losing definition as they zoom in, but these maintain a clear view of the image right through the zoom option.
