Ef-S 18-200Mm F/3.5-5.6 Is Lens - Canon EOS 5D Mark 2 Tutorials Manual

VII.NEW ACCESSORIES AND LENSES
The advanced Image Stabilization system also senses camera motion and automatically
optimizes the Image Stabilization for either normal shooting or panning (where vertical
stabilization is applied, but horizontal isn't to allow for side-to-side panning). The Image
Stabilization system also has a function that detects the use of a tripod and responds
accordingly. Other features that add to image quality are the 6-blade, circular aperture for
exquisite soft-toned images, and the high speed, optimized AF system. As a finishing
touch for convenience and safety, the lens includes a built-in zoom locking mechanism
that holds the lens to its shortest, un-extended length.
