EF 16-35mm f/2.8L III USM
新一代專業f/2.8大光圈全片幅超廣角變焦鏡頭，全新光學設計兼配備大量特殊鏡片以支援超高像素，包括 2片高精度大口徑雙面玻璃鑄模（GMo） 非球面鏡片、1片玻璃研磨（Ground）非球面鏡片大大修正變形、視場彎曲及像散（Astigmatism），大幅改進整個變焦範圍由畫面中心至邊緣的影像質素。2片UD超低色散鏡片有效消除各焦段的橫向色差及色彩模糊現象，達至高解像度及高反差的影像。鏡頭亦分別於第一片鏡片加入「SWC次波長結構塗膜」（Subwavelength Structure Coating）及第二片鏡片加入「ASC空氣球體塗膜」（Air Sphere Coating） ，有效抑制鬼影與眩光、效果非一般塗膜可比。加上經改良的鏡頭結構及加入氟塗膜（Fluorine Coating），讓鏡頭的耐用度得以全面提升。
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
