This is how image stabilisation works

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.
