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.
*Lineup is as of October 2023.
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.
*Function available on supported cameras only. Available corrections or auto correction functionality may vary depending on the camera model.
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.

MTF CHART
There are two types of MTF chart. One considers the diffraction quality of light, which is called "Diffraction MTF", and the other, "Geometrical MTF" does not.
The quality of light appears in the diffracted light, and becomes more distinct as the F value gets bigger, resulting in lower image quality. Also, diffracted light exists at every aperture, which is why Sigma has been releasing Diffraction MTF data from the beginning since it is very close to the actual image data.
The advantage of using "Geometric MTF" data is that it is easy to measure and calculate since it does not consider the diffraction quality of light, yet it tends to show higher values in the graph than actual images.
The readings at 10 lines per millimeter measure the lens's contrast ability ( red lines), repeating fine parallel lines spaced at 30 lines per millimeter measure the lens's sharpness ability (green lines), when the aperture is wide open.
Fine repeating line sets are created parallel to a diagonal line running from corner to corner of the frame, are called Sagittal lines (S) and sets of repeating lines vertical to these lines are drawn, called Moridional (M) line sets.
*The MTF chart gives the result at the wide-open aperture.

Inner focus system
To increase stability, this lens configuration uses movable internal lens elements that adjust focus without changing the length of the lens barrel.
Compatible with Lens Aberration Correction
Matching the optical characteristics of the lens, this function performs in-camera corrections of peripheral illumination, chromatic aberrations, distortion, and more, to further enhance image quality.
*Function available on supported cameras only. Available corrections or auto correction functionality may vary depending on the camera model.
*On cameras where lens aberration correction is controlled with 'ON' or 'OFF' in the camera menu, please set all aberration correction functions to 'ON'(AUTO).
Super Multi-Layer Coating
SIGMA's own Super Multi-Layer Coating suppresses flare and ghosting by preventing reflections with in the lens. All lenses in the current SIGMA range feature this original technology. In digital cameras, flare and ghosting may also be caused by reflections between the image sensor and lens surfaces. Here too, SIGMA's Super Multi-Layer Coating is highly ef fective, assuring images of outstanding contrast.
Linear focus / Non-linear focus (for L-Mount only）
A focus movement method of interchangeable lenses for mirrorless cameras (DN lens) in relation to the rotational angle of the focus ring during manual focusing.
With "non-linear focus," the amount of focal point movement varies depending on the focus ring rotational speed.
With linear focus, if the focus ring rotational angle is the same, the amount of focal point movement remains the same regardless of the focus ring rotational speed.
