Does my Canon Rebel XTi have Image Stabilization built into it?
While the Canon Rebel XTi does not contain Image Stabilization (IS), Canon offers a variety of IS-enabled lenses that make shooting sharp images under low-light conditions that much easier. Canon’s IS-enabled lenses allow you to shoot images at 3 – 4 shutter speeds slower than non-IS-enabled lenses. The accepted rule is to never shoot hand-held at shutter speeds slower than the focal-length of the lens being used. Accordingly, a 200mm lens should not be hand-held at speeds slower than 1/200th, and a 20mm lens should not be hand-held at speeds slower than 1/20th. If however your lens is IS-enabled, you can now hand-hold a 200mm lens as slow as 1/25th and a 20m lens as slow as 1/2-second and still maintain image sharpness.
