Large F2.8 Aperture and Superb Image Quality

The SIGMA 18-50mm F2.8 DC DN | Contemporary for L-Mount 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.

Exceptionally Compact and Lightweight Body
Ideal for Mirrorless Cameras

The SIGMA 18-50mm F2.8 DC DN | Contemporary for L-Mount 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. The lens is currently the smallest and lightest in its class※1, boasting a maximum diameter of φ61.6mm, a length of 76.5mm and weight of 290g, yet still maintains a constant aperture of F2.8. Combined 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.

Supports Various Shooting Situations

The SIGMA 18-50mm F2.8 DC DN | Contemporary for L-Mount 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. This has been achieved by using a stepping motor as the AF actuator. 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.

Stunning Versatility.

A large F2.8 aperture zoom lens that need never leave your camera

This exceptionally small, light and bright standard zoom for crop-sensor mirrorless cameras is the ultimate workhorse lens.

SIGMA’s first APS-C size mirrorless zoom lens has a versatile full-frame equivalent zoom range of 27-75mm, which makes it ideal for a wide range of photo and video applications including landscapes, portraits, street photography, architecture and events. It can also be used for macro-style close-up photography owing to its maximum magnification of 1:2.8※1, which allows a minimum focusing distance of just 12.1cm. In terms of its bright F2.8 aperture, it makes for easier hand-held low-light shooting and provides a shallow depth-of-field for high-impact results.

Autofocus is exceptionally fast and quiet thanks to the stepping motor, which can be particularly useful when shooting video, or fast-moving subjects such as children and animals. The lens’ exceptionally small and light form factor that weighs less than 300g makes it perfect as a first interchangeable lens, and as a sub-lens for full-frame bodies※2, as well as for various shooting situations.
