Sigma 18 50mm f 2.87/26/2023 ![]() *The minimum focusing distance and maximum magnification are both values at the wide end. With an emphasis on making the lens as versatile as possible in a wide variety of shooting conditions, SIGMA designed the lens with a minimum focusing distance of 12.1cm and maximum magnification of 1:2.8*, making it also ideal for close-ups. The 18-50mm F2.8 DC DN | Contemporary, which combines compactness, light weight, high performance, and large aperture, supports a variety of shooting situations, from introductory single-lens mirrorless cameras to video shooting and combination with full-frame cameras. Since it is small and lightweight, it can be used flexibly in situations such as handheld shooting, which requires high mobility, gimbal shooting, one-man operation video shooting and vlogging.Ĭombined with the “Pocketable Full-Frame” SIGMA fp, the total weight is only 712g, and it can also be useful as a sub-lens for full-frame cameras (used in crop mode) to keep weight down. This has been achieved by using a stepping motor as the AF actuator. The SIGMA 18-50mm F2.8 DC DN | Contemporary has fast and near-silent AF that makes it perfectly suited to a range of photographic applications, including shooting in quiet environments, recording videos and capturing fast-moving subjects. *1 As an AF compatible, F2.8 constant aperture zoom lens for APS-C (as of October 2021, by SIGMA) By deliberately using metal for some of the internal structure, the parts could be much thinner and have a higher rigidity, ensuring the lens can stand up to frequent, heavy use. This ensures stable performance and good operability when used in changing temperatures. A polycarbonate called Thermally Stable Composite (TSC) was used for the construction of the barrel, which is sleek, robust, and importantly has a thermal conductivity close to that of aluminum. To keep the lens as light as possible, SIGMA constructed the body from carefully selected materials. ![]() The lens is currently the smallest and lightest in its class?1, boasting a maximum diameter of f65.4mm, a length of 74.5mm and weight of 290g?2, yet still maintains a constant aperture of F2.8. This makes it a perfect workhorse lens that is ideal for general day-to-day use. The SIGMA 18-50mm F2.8 DC DN | Contemporary is remarkably compact, matching the portability of APS-C mirrorless camera bodies. This has all been made possible by the latest optical design technology at SIGMA’s only production base in Aizu, where all SIGMA lenses are built.Įxceptionally compact and lightweight body ideal for mirrorless cameras 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. The bokeh is smooth and attractive so doesn’t distract from the in-focus subject. This makes it easy to achieve blurry backgrounds, which is ideal for shooting attractive portraits and close-ups. 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. Large F2.8 aperture and superb image quality
