Benefitting working in difficult lighting conditions, an Optical Image Stabilizer has been integrated into the lens design to minimize the appearance of camera shake by up to an effective four shutter speed steps. For fast, smooth, and near-silent autofocus performance, a ring-type USM (Ultrasonic Motor) AF motor is employed and benefits from an internal focusing design to maintain the overall length of the lens during use. Full-time manual focus override can also be utilized for fine-tuned focusing precision as closely as 11" throughout the zoom range.
When paired with an optional Protect filter, this lens also exhibits a dust- and water-resistant construction to enable its use in inclement conditions.
