- First EF-S*1 ultra-wide angle zoom lens with optical Image Stabilizer, offering focal length equivalent to approximate 16-29mm in 135 format
- Newly developed 14 elements in 11 group optical design
- Adoption of a large diameter PMo aspherical element, made possible by Canon innovative production technique, in addition to new 4-group zoom optics achieves a compact design with lens length shortening to 72mm and weights only 240g.
- Use of a large diameter PMo aspherical element and a glass-molded (GMo) aspherical element to correct aberration phenomena for higher image quality.
- 1 Ultra-Low Dispersion (UD) lens reduces chromatic aberration throughout the zoom range
- Ultra-compact Image Stabilizer offers shake compensation up to 4-stop shutter speed*2 and automatically detects normal shooting and panning for optimal compensation
- Quiet and smooth continuous AF is supported in movie shooting and Live View shooting*3 by the adoption of Stepping Motor (STM)
- Rear focus system, high-speed CPU and improved AF algorithms provide high-speed auto focus; full time manual focus is also supported
- The front lens element does not rotate during focus, facilitating the use of polarizing filter
- 7-blade circular aperture for beautiful out-of-focus image
- Lens coatings are optimized to minimize ghosting and flare
