Sigma 10-18mm f/2.8 DC DN Contemporary for Leica L Mount APSC

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.

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*, with a length of 62.0mm, a maximum diameter of 72.2mm, and a weight of 260g*. 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.

*As an AF F2.8 zoom lens for mirrorless cameras with an APS-C sensor. As of October, 2023 by SIGMA.
*The values are for L-mount.

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.

*The values are for L-mount.

Mount with dust and splash resistant structure

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

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.
