Image Stabilizer lenses and autofocus

When shooting with an image stabilized lens, especially a long telephoto, if you don’t need to use the IS because your shutter speed is fast enough to avoid camera shake, try turning it off for even faster autofocus. This is especially useful for fast moving subjects where absolute AF speed is important. I mainly use the stabilizer when shooting speakers or subjects in low light when I feel the ISO starts to lose sharpness, which is around 1600 ISO for a Canon 2o MP full frame DSLR camera.
