In certain situations it helps to have image stabilisation during photography and it is essential for DSLR videography.
One doesn’t see disassembled lenses every day (unless working in a camera factory or repair shop) so I think it may be interesting for many of you how such a lens works in practice. PetaPixel posted a video from YouTube about the movement of the optical image stabilisation element of a Canon telephoto lens (manufacture of a lens can be seen in an earlier post).
You can watch how the image stabilisation works in Canon or Nikon lenses on their websites linked to their names.
