A system for zooming and holding an image of an object/objects in a vision zone is proposed. The vision zone comprises—a first sector having a first zoom factor, first size, first contour, and first position, and—a second sector having a second zoom factor, second size, second contour, and second position. The second zoom factor may differ from the first one. The first sector can be disposed inside of the second sector, the contours may have or may not have a common point. The system is capable of—changing the first and second zoom factors independently, and/or—respectively decreasing/increasing the first size in response to decreasing/increasing the second size and vice-versa, and/or—changing the sectors' positions. In some embodiments, the vision zone comprises multiple sectors. The system can be built employing conventional optical/optoelectronic components/technologies, and associated with optical/electronic or optical-electronic sights, binoculars, video/photo cameras (including digital ones), etc.
