Metoda de compensare optica, folosita de Canon, a miscarilor (tremuraturilor) fotografului care foloseste obiective cu focala lunga si timpi lungi de expunere; se realizeaza prin deplasarea intr-un plan perpendicular pe axa optica si pe directia dominanta de miscare a unui grup de lentile, din aceasta cauza denumit stabilizator . Permite obtinerea de imagini clare cu obiective de 300 - 400 mm chiar si la timpi de 1/30 sec., dar fotograful trebuie sa aleaga un mod specific de vibratie.
