Press release:

SIGMA Announces 10-18mm F2.8 DC DN | Contemporary, the World's Smallest and Lightest F2.8 Zoom Lens for APS-C Mirrorless Cameras

Ronkonkoma, NY – October 5, 2023 – SIGMA Corporation of America, the US subsidiary of SIGMA Corporation (CEO: Kazuto Yamaki. Headquarters: Asao-ku, Kawasaki-shi, Kanagawa, Japan) is pleased to announce the SIGMA 10-18mm F2.8 DC DN | Contemporary lens. This is the first SIGMA lens being announced and released concurrently for the L-Mount, Sony E-mount and Fujifilm X Mount. The lens will be available through authorized retail partners on October 26, 2023 for $599.

This is the world's smallest and lightest F2.8 zoom lens designed for APS-C format mirrorless systems at just 2.8 x 2.4 inches (72.2 x 62mm) and 9.2 ounces (260g)*1. The lens covers a 15-36mm (35mm equivalent) focal range, with a fast F2.8 constant aperture. Paired with the 18-50mm F2.8 DC DN | Contemporary, this duo of lenses covers a 15-75mm (35mm equivalent) range with the same bright F2.8 maximum aperture at a combined weight of under 19.5 ounces (550g).

The SIGMA 10-18mm F2.8 DC DN | Contemporary uses an aspherical concave lens with a large polarization ratio and high refractive index in the first group, reducing the number of elements in the first group and shortening the overall length. Additionally, a new push-on petal type hood has been developed. Thanks to the new structure with a spring and lever, which is not utilized by any other manufacturer, the hood has been made both thinner and smaller, which also contributes to the overall compactness of the lens.

The optical design of the lens delivers a short 4.6 inch (11.6cm) minimum focusing distance and a maximum magnification ratio of 1:4 at the wide end, allowing for close-up photography with pleasing background separation. The optical design also minimizes focus breathing, and the stepping motor delivers swift, quiet autofocus during both still and video use.

Thanks to its high optical quality and compact size, the SIGMA 10-18mm F2.8 DC DN | Contemporary lens is an excellent choice for travelers, adventure photographers, vloggers, content creators, and family photographers who want great image quality when paired with today's leading lightweight crop-sensor cameras on the three supported mirrorless platforms.

Create expressive images on the go with the world's smallest and lightest ultra-wide-angle zoom lens for APS-C cameras*

The SIGMA 10-18mm F2.8 DC DN | Contemporary is the world's smallest and lightest ultra-wide- angle zoom lens for APS-C cameras*2, covering an effective focal range of 15-27mm (35mm equivalent). With ultra-sharp optics, a bright F2.8 aperture and a newly developed push-on petal type lens hood, photographers can create expressive images anytime, anywhere. The lens features a unique aspherical element that reduces the overall size of the lens and enhances image quality.

An 11.6cm (1:4) minimum focusing distance to produce unique compositions, with expansive backgrounds and pleasing bokeh. With a weight of only 260g*3, a fast AF stepping motor and minimal focus breathing, the lens can be easily mounted onto a motorized gimbal to create impressive video content for social media use and professional projects. The lens is available for L-Mount, Sony E-Mount and FUJIFILM X Mount systems.

Key Features

1. Large-aperture, ultra-wide-angle zoom with expressive imaging capabilities

By utilizing unique optics which have been designed to correct lens aberrations, the SIGMA 10-18mm F2.8 DC DN | Contemporary produces images that are sharp across the entire image.

Aspherical lens, special low-dispersion glass

The use of an aspherical lens with large eccentricity and refractive index as the first lens element has enabled a lens construction with a reduced number of elements. 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 11.6cm, maximum magnification ratio 1:4
Create expressive close-up images using the 11.6cm minimum focusing distance when shooting at 10mm. With a magnification ratio of 1:4, the lens captures unique portraits, still life and more.

2. Extremely compact and lightweight

The SIGMA 10-18mm F2.8 DC DN | Contemporary is the world's smallest and lightest ultra-wide angle zoom lens for APS-C cameras*2, with a length of 62.0mm, a maximum diameter of 72.2mm, and a weight of 260g*3. The lens can be carried around with ease or attached to an APS-C mirrorless camera and a gimbal to create an ultra-portable video setup.

Newly developed push-on petal type hood

A newly developed push-on petal type hood is included with the lens. Unlike the conventional bayonet type lens hoods that attach with a rotating movement, this push-on type lens hood is attached onto the lens using a spring and lever system. The implementation of this new design reduces the size and thickness of the hood so that it matches the compact size of the lens.

Compact, lightweight, high-performance F2.8 constant aperture zoom lens series

When combined with the SIGMA 18-50mm F2.8 DC DN | Contemporary, a total, unbroken focal range of 15-75mm (35mm equivalent) with a constant F2.8 aperture can be covered. The combined weight of both lenses is only 550g*3.

Fast-growing lineup of lenses for APS-C mirrorless cameras

In addition to the SIGMA 18-50mm F2.8 DC DN | Contemporary, the lineup of lenses for APS-C mirrorless cameras includes 16mm, 23mm, 30mm, and 56mm prime lenses, all with F1.4 brightness. This flexible lens selection can be used for a wide variety of photographic applications*4.

Mount with dust and splash resistant structure

The lens mount incorporates rubber sealing to protect it from dust and water drops.

3. Ideal for landscapes, travel, video and online content creation

With ultra-wide focal length, portable body and razor-sharp optics, the SIGMA 10-18mm F2.8 DC DN | Contemporary is the perfect portable option for landscape, travel, interior and street photography. It also boasts impressive video capability owing to its bright F2.8 aperture, which makes it well-suited to shooting in low-light environments and creating a shallow depth-of-field. The ultra-wide angle-of-view is ideal for hand-held vlogging that requires the capture of both the subject and the environment.

Designed to minimize focus breathing

The lens has been designed to suppress focus breathing. The change in angle-of-view due to focus shift is minimized, creating a natural-looking focus shift when recording video.

Supports various camera functions

The lens is compatible with the electronic image stabilization function, aberration correction function, DMF, and AF+MF in camera bodies from various manufacturers. The advantage using this ultra-wide-angle lens is that it provides a generous angle-of-view even when the electronic image stabilization function crops the image.*5

Stepping Motor

A fast and quiet stepping motor is used to deliver precise AF when shooting stills and video. It is fully compatible with in-camera AF tracking modes.
