Compose an image at will, without regard to shooting distance or ambient lighting constraints, to produce crisp, tack sharp images from f/1.8 full open aperture. The slight wide-angle delivers a new photographic perspective. Thanks to optimal use of sophisticated glass materials and highly advanced optical design, the lens provides outstanding image quality with maximum aberration compensation. Expand your photographic possibilities by shooting close. Fast, quiet AF is achieved thanks to the Ultrasonic Drive. Optimal relative illumination means no dark corners. Special lens coatings suppress ghosting and flare for flawless, crystal clear images, and repel water and fingerprints on the front element. Moisture-resistant construction provides an extra layer of protection when shooting outdoors in adverse weather conditions.
