-EF ultra wide angle zoom lens with the world’s widest1 angle focal length of 11mm, a stunning diagonal angle of view of 126°05’
-Newly developed 11 elements in 16 groups design with 4 aspherical lenses, 1 Super UD and 1 UD lens to achieve high image quality
-The use of 1 ground aspherical lens with largest diameter2 in the world, 1 glass-molded aspherical lens with largest diameter class3 in the world and 2 other glass-molded aspherical lenses ensures distortion is well compensated across the full zoom range. Curvature of field and astigmatism are significantly reduced, results in higher image quality across the entire image including the periphery.
-The use of a super UD lens and a UD lens corrects the magnification-type chromatic aberration often occurs easily with an ultra-wide lens. Color blurring around the edges of subject is also reduced throughout the zoom range
-Application of SWC (Subwavelength Structure Coating) on 2 lens surfaces and ASC (Air Sphere Coating) on 1 lens surface 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 0.16x maximum magnification (at 24mm)
-Rear focusing design, ring USM and optimized AF algorithm bring fast and quiet autofocus with full time manual focus
-New optimized mechanical structure brings a durable zoom mechanism with great precision. In addition, resistance to shock and vibration of the lens barrel has been improved to cope with the demand of professional users
-Optimized lens placement and coatings for digital cameras to ensure excellent color balance and minimize ghosting and flare
-Fluorine coating on foremost and rearmost lens surfaces makes lens cleaning easier
-Integrated petal-type hood to control flare and protect the large diameter front element
-Dust and water resistance design*4 to enable shooting in harsh conditions
-New "Lens Cap 11-24" and "Lens Case LP1424" included
