General purpose lens that helps reduce camera shake

This is the world's first interchangeable SLR lens equipped with an Image Stabilizer. You can take sharp pictures even in low-light conditions when camera shake would normally blur the shot. Effective for sunsets and places where you cannot use a tripod.
