Benefiting the optical attributes is a Hybrid IS image stabilization system that serves to minimize the appearance of camera shake for sharper results when working handheld and in difficult lighting conditions. A lead screw-type STM stepping motor also benefits handling by producing fast, smooth, and quiet autofocus performance to suit both stills and video applications. This AF motor can be manually overridden at any time by turning the dedicated focusing ring for making fine-tuned adjustments.
