Benefitting the optics, this zoom sports a splash and dust-resistant design to suit working in inclement weather conditions. This lens also features a stepping motor for fast and quiet autofocus performance that benefits both stills and movie shooting. An internal focusing design maintains the overall lens length during operation and also quickens focusing speeds. Additionally, POWER O.I.S. (Optical Image Stabilizer) benefits this expansive wide-to-tele zoom range by compensating for camera shake for sharper handheld shooting.
