The SIGMA 10-18mm F2.8 DC DN | Contemporary is the world’s smallest and lightest ultra-wide- angle zoom lens for APS-C cameras, covering an effective focal range of 15-27mm (35mm equivalent). With ultra-sharp optics, a bright F2.8 aperture and a newly developed push-on petal type lens hood, photographers can create expressive images anytime, anywhere. The lens features a unique aspherical element that reduces the overall size of the lens and enhances image quality. An 11.6cm (1:4) minimum focusing distance produces unique compositions, with expansive backgrounds and pleasing bokeh. With a weight of only 260g, a fast AF stepping motor and minimal focus breathing, the lens can be easily mounted onto a small gimbal to create impressive video content for social media use and professional projects.
