Features Highlight
- Professional Full-frame f/2.8 Large Aperture Ultra-Wide Angle Zoom Lens with Ultra-high Resolution
- Newly developed 16 elements in 11 groups design with 3 aspherical lenses and 1 UD lens to achieve even higher image quality than its predecessor
- Use of 2 large-diameter Glass-molded (GMo) double-surface aspherical lens elements and 1 ground aspherical lens to reduce distortion, curvature of field and astigmatism significantly, achieving huge improvement in image quality from center to peripheral throughout the zoom range
- Use of 2 Ultra-low Dispersion (UD) lenses to minimize chromatic aberration of magnification and reduce color blur around the edges of subjects, giving high quality image of high levels of resolution and high contrast
- Application of SWC (Subwavelength Structure Coating) on the first lens element and ASC (Air Sphere Coating) on the second lens element to suppress the ghosting and flare caused by light with a high angle of incidence, which are not possible with ordinary coating
- 9-blade circular aperture produces beautiful out-of-focus image
- 0.28m minimum focusing distance with 0.25x maximum magnification (at 35mm)
- Inner focusing design with the Ring-type USM supports low-speed driving to provide high-speed, silent and smooth AF during photo and video shooting
- Optimized lens coatings for digital cameras to ensure excellent color balance and minimize ghosting and flare
- Lens structure with improved zoom durability and resistance to shock and vibration of the barrel to meet the demand of professional users
- Fluorine coating on foremost and rearmost lens surfaces makes lens cleaning easier
- Dust and water resistance design1 to enable shooting in harsh conditions
- A new petal-type Lens Hood EW-88D and Lens Case LP-1222 are included
1 Requires optional Canon 82mm Protect filter and use with EOS-1D Series or EOS-1V body, however it is not recommended for use under rain
