Compact L-series telephoto lens with an Image Stabilizer which compensates for camera shake with equivalent effect of a shutter speed two stops faster. Two Image Stabilizer modes are provided: Stabilizer Mode 1 (the same mode featured on the EF 75-300mm f/4-5.6 IS USM) and the new Stabilizer Mode 2 which steadies the image during horizontal or vertical panning.
The image stabilizer also functions when using the Extender EF1.4xII or Extender EF2xII to provide that elusive 600mm shooting capability.
