Used in conjunction with multiple aspherical lenses and special low-dispersion glass, the lens can produce high resolution images whilst remaining compact and lightweight. Minimum Focusing Distance and Maximum Magnification RatioCreate expressive close-up images using the 11.6 cm minimum focusing distance when shooting at 10mm. With a magnification ratio of 1:4, the lens captures unique portraits, still life and more.Extremely Compact and LightweightThe SIGMA 10-18mm F2.8 DC DN Contemporary is the world’s smallest and lightest ultra-wide angle zoom lens for APS-C cameras, with a length of 62 mm, a maximum diameter of 72.2 mm.
