(From Canon lens literature) The EF 24-105mm ƒ/3.5-5.6 IS STM lens is the first EF-series zoom lens for full-frame sensor cameras to include a lead screw-type stepping motor (STM) that provides virtually silent AF while shooting video. The 24-105mm is one of the most versatile focal range options in the EF lineup as it can be used as a wide-angle lens while out on the town as well as a portrait-length zoom when trying to get closer to your subjects.
The Optical Image Stabilizer provides up to four shutter speed steps of correction,** while two aspheric lenses plus a UD lens combine to provide high-quality results for both still images and video. New to the EF 24-105mm ƒ/3.5-5.6 IS STM lens is a seven group zoom optical formula that enables a conveniently compact design while maintaining high-quality optical performance. The lens’ lightweight inner focusing system, high-speed CPU, and improved AF algorithm enables high-speed AF. In addition, the seven bladed circular aperture combined with the optimized lens placement and coatings delivers beautiful, soft bokeh, and exceptional color balance, while helping to minimize ghosting and flare. The new EF 24-105mm ƒ/3.5-5.6 IS STM lens provides a lighter and more affordable option with STM focus capabilities to Canon’s popular EF 24-105mm ƒ/4L IS USM lens.
