The SIGMA 18-50mm F2.8 DC DN | Contemporary covers 27mm to 75mm in the 35mm format, and has a wide aperture of F2.8 throughout the entire zoom range. This makes it easy to achieve blurry backgrounds, which is ideal for shooting attractive portraits and close-ups. The bokeh is smooth and attractive so doesn't distract from the in-focus subject. The lens's three high-precision glass-molded aspherical elements coupled with the minimization of the total number of elements yields superb optical quality without excessive weight, and the use of in-camera aberration correction further eliminates optical imperfections such as distortion and vignetting.

Exceptionally compact and lightweight body ideal for mirrorless cameras 
The SIGMA 18-50mm F2.8 DC DN | Contemporary is remarkably compact, matching the portability of APS-C mirrorless camera bodies. This makes it a perfect workhorse lens that is ideal for general day-to-day use.
