Binoculars with image stabilization are always worthwhile if you intend to use them with higher magnification, but don’t want to mount them on a tripod. Such binoculars are also worthwhile for people who do not have a steady hand.
The smallest trembling movements are compensated for by electronic sensors. Even binoculars with 15x magnification can be kept absolutely still. The image appears visually very sharp, because any image shake has been eliminated.
