MTF Chart
The MTF (Modulation Transfer Function) is one of the measurements for evaluating a lens’ performance, and it shows how faithfully the contrast of the subject can be reproduced on the image plane. The horizontal axis shows the image height (distance from the center of the image in mm) and the vertical axis shows the contrast value (maximum value is 1).
The closer the 10 line pairs/mm curve is to 1, the higher the contrast and clarity of the lens is, and similarly, the closer the 30 line pairs/mm curve is to 1, the better the resolution and sharpness of the lens is.*The MTF chart depicts the result at the wide-open aperture.
*For mirrorless lenses that support distortion correction, the horizontal axis shows the image height equivalent to when an L-Mount lens is attached to a Sigma L-Mount camera with distortion correction applied. (The effect of distortion correction may differ depending on the mount and camera used.)
*The spatial frequency indicates the variation on the image plane before distortion correction is performed. -

A member of the high-performance Contemporary line, featuring Sigma’s latest technologies
For optimal balance with light, compact camera bodies with a short flange back distance, Sigma designed the new Sigma 30mm F1.4 DC DN | Contemporary lens to be extremely compact. Moreover, the special design of the focus lens group allows fast and smooth AF performance for videography and more. This lens combines a compact design and comfortable operation while prioritizing outstanding image quality. Featuring Sigma’s latest technologies, this lens digitally corrects optical distortion.
-
Extra-long Hood (Supplied)
The included lens hood is extra-long and features an anti-reflective coating to manage unwanted light. The hood also includes rubber and anti-slip textures to make it easier for the photographer to hold while shooting.
-
TSC used for a more compact structure and enhanced performance
Since new material (*) TSC (Thermally Stable Composite) is highly elastic, it exhibits minimal deformation. Parts made of TSC are therefore less prone to develop gaps over time. The Sigma 30mm F1.4 DC DN | Contemporary features a lens barrel and aperture parts made of TSC, contributing to compactness and smooth aperture operation. TSC improves precision of lens element cells and focus components, enhancing overall performance.
(*) TSC (Thermally Stable Composite) is a polycarbonate with a thermal expansion rate similar to aluminum, ensuring high manufacturing precision and excellent affinity to metal parts.
-
Combining compactness with outstanding optical performance
The front lens element features high-refractive-index, high-dispersion glass for greater power and a shorter overall length. Two aspherical elements ensure excellent image quality and compactness. The design maintains outstanding stability whether handheld or supported. Materials and construction contribute to a light yet solid structure—an unprecedented blend of performance and portability.
-
Mount with Dust and Splash Resistant Structure
The mount features a special sealing * to make the lens a reliable choice in a wide variety of environments.
* Not featured on Sony E-mount, Canon EF-M mount, and Micro Four Thirds mount. -
Image quality rivaling that of our Art line lenses
A compact, lightweight lens offering outstanding image quality with F1.4 brightness
This design incorporates one aspherical and one double aspherical element, plus a high-refractive-index element with anomalous partial dispersion. The result is bright, edge-to-edge clarity with minimized chromatic aberration and distortion—delivering Art-grade image performance in a smaller body.
* Limited to what the camera supports.

Designed to minimize flare and ghosting
From an early stage in design, flare and ghosting were analyzed to ensure resilience to strong incident light. Sigma’s Super Multi-Layer Coating reduces flare and ghosting for sharp, high-contrast results even in backlit conditions. The supplied hood blocks extraneous light that could degrade image quality.
-
The stepping motor delivers excellent autofocus with quiet performance.
The optical design and stepping motor deliver smooth autofocus during video shooting. The lens design fully accommodates the Fast Hybrid AF of Sony E-mount cameras for super-fast autofocus functionality. Using face recognition AF results in consistent autofocusing on faces, even as the subjects move.
-
Shallow depth of field for a beautiful bokeh effect
The large F1.4 aperture provides a shallow depth of field and smooth, beautiful bokeh previously unavailable in standard lenses for mirrorless cameras.
-
High-precision, rugged brass bayonet mount
The brass mount combines high precision with rugged durability, ensuring long-term reliability. Its treated surfaces enhance strength and resistance to wear.

Rounded diaphragm
The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.
Combining outstanding optical performance and compact design Introducing a new F1.4 standard lens for mirrorless cameras
Offering an opportunity to experience
the fun of shooting wide open,
with F1.4 brightness
Sigma 30mm F1.4 DC DN | Contemporary large-aperture standard lens gives owners of mirrorless cameras the opportunity to experience the fun of shooting wide open, with F1.4 brightness. Photographers will enjoy the beautiful bokeh effect that only a large-aperture lens can offer and the exceptionally sharp optical performance expected from a fine prime lens. Leveraging Sigma’s latest technologies and design insights, this new lens fulfills the concept of the Contemporary line, in which varied elements come together in optimal balance.
A prime lens with a focal length of around 50mm and F1.4 brightness offers an angle of view very similar to human vision. The photographer can use the shallow depth of field at wide-open aperture to take stunning portraits and tabletop still life shots. Or he or she can close the aperture for greater depth of field and shoot landscapes or snapshots. In this way, standard lenses allow photographers to enjoy so many of the fundamental methods of photography and have thus been favorites for decades. Photographers can experience F1.4 brightness and standard lens functionality with a 35mm equivalent focal length of 60mm on the Micro Four Thirds system, 48mm on the Canon EF-M Mount system and 45mm on other systems.
