Product Features

Standard zoom, F2.8 brightness, and sharp image quality in an overwhelmingly compact and lightweight body

A palm-sized, large-aperture standard zoom lens you can carry with you every day

Introducing the 18-50mm F2.8 DC DN Contemporary, Sigma's first APS-C size mirrorless-exclusive zoom lens.
The lens features an easy-to-use zoom range of 27-75mm (35mm film format equivalent), a brightness of F2.8 that allows you to enjoy bokeh expression, and sharp images achieved by the latest optical design technology, all in an overwhelmingly compact and lightweight body. With a minimum focusing distance of 12.1cm and a magnification ratio of 1:2.8*1, you can take advantage of the compact photographic system to shoot close-up shots of your subjects.
The agile and quiet AF using a stepping motor is also ideal for movie shooting. The lightweight photographic equipment can be used in a variety of styles, including hand-held and gimbal shooting, regardless of the weight of the equipment.
The compact, lightweight, and bright standard zoom lens is ideal for a variety of shooting situations, from your first interchangeable lens to a lens for video shooting to a sub-lens for a full-size camera*2. The palm-sized large-aperture standard zoom lens maximizes your photographic pleasure.

Large-aperture F2.8 standard zoom lens for sharp images

The 35mm format equivalent covers a range of 27mm to 75mm, and with a brightness of F2.8 that does not change the F value throughout the entire zoom range, this easy-to-use zoom lens expands the range of your shooting. The short flange back allows for a high degree of freedom in design and the use of optical compensation functions on the camera side, the number of lenses has been minimized by the latest optical design technology, and three high-precision glass-molded aspherical lenses made possible by Sigma's only production facility in Aizu, Japan, give the lens an unimaginable compactness and lightweight size. The lens is so compact and lightweight that it is hard to imagine the size of the lens.
With an emphasis on ease of use during shooting, the minimum focusing distance of 12.1 cm and a magnification ratio of 1:2.8* allow photographers to take advantage of the compact shooting system to shoot freely without being restricted by the distance to the subject. In terms of image creation, the large F2.8 aperture allows the photographer to enjoy bokeh expression while at the same time achieving a sharp image of the in-focus area. 
The compact shooting system allows the photographer to enjoy the full pleasure of photography.

Unparalleled compact and lightweight body ideal for mirrorless camera systems

The 18-50mm F2.8 DC DN Contemporary's main feature is its overwhelmingly compact and lightweight body, which maximizes the advantages of the excellent portability of APS-C mirrorless cameras.
Despite its large aperture of F2.8, it is the smallest and lightest in its class*1 with a maximum diameter of 65.4mm, length of 74.5mm, and weight of 290g*2. This makes the large-aperture standard zoom easy to carry around with you in your daily life.
Because of the compact and lightweight body, the materials and construction of the parts have been carefully selected. Polycarbonate TSC (Thermally Stable Composite), which has a thermal shrinkage rate similar to that of aluminum, is used in appropriate locations to ensure stable performance, good feel, and light weight even in environments with temperature fluctuations. The use of metal in some parts of the internal structure ensures thinner parts and a high sense of rigidity, ensuring sturdiness and a light operational feel that can withstand daily use.

Support for Various Shooting Situations

A stepping motor is used as the AF actuator. The agile and quiet AF is ideal for both still and moving image shooting. Since photographic equipment can be kept compact and lightweight, it can be used flexibly in all situations, including hand-held shooting, shooting with gimbals, one-man operation video shooting, and Vlog shooting, where high mobility is required.
It can reduce the total weight and is useful as a sub-lens for full-size cameras when you want to reduce your luggage as much as possible.
The 18-50mm F2.8 DC DN Contemporary, which combines compactness, light weight, high performance, and a large aperture, can be used in a variety of shooting situations, from introductory SLR mirrorless shooting to video shooting and combination with a full-frame camera.
