Design detail

Combining outstanding optical performance and compact design Introducing a new F1.4 standard lens for mirrorless cameras

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 and 45mm on the Sony E-mount system.

About the lens name

SIGMA lenses with “DC” in the name are designed for optimal performance on cameras with APS-C image sensors. When a DC lens is used with a camera with a full-frame image sensor, vignetting will occur. Photographers are advised to adjust image area settings for optimal image results. SIGMA lenses with “DN” in the name are designed for optimal performance on cameras with a short flange back distance

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.

Combining compactness with outstanding optical performance

The front lens element features high-refractive index, high-dispersion glass for extra power and a shorter overall lens length. To optimize the lens for mirrorless cameras, two aspherical lens elements help ensure outstanding image quality and overall compactness. The SIGMA 30mm F1.4 DC DN | Contemporary features SIGMA’s inner focus technologies, while lighter lens elements in the focus lens group make possible a more compact actuator. Moreover, this lens offers outstanding stability whether the photographer is shooting handheld or has the camera placed on a surface. Structurally, the lens features materials and parts that contribute to its compact, lightweight structure. In summary, this is an unprecedented lens that combines outstanding optical performance with exceptional portability and usability.

A compact, lightweight lens offering outstanding image quality with F1.4 brightness

Image quality rivaling that of our Art line lenses

In addition to featuring an optimized layout and power distribution, this lens incorporates one aspherical lens element and one double aspherical lens element, as well as an element made of high-refractive index, high-dispersion glass with high anomalous partial dispersion. By effectively leveraging these technologies, the lens delivers an outstanding level of light to the edges of the image while minimizing lateral chromatic aberration. To correct distortion, the lens takes advantage of the image correction capabilities of the mirrorless camera body, using the corrective power of the optical system to enhance sharpness. The final result is an extremely compact lens that delivers image quality that rivals that of our Art line lenses.

Shallow depth of field for a beautiful bokeh effect

The large-diameter lens with F1.4 brightness makes possible a shallow depth of field for a beautiful bokeh effect—unavailable until now in a standard lens for mirrorless cameras.

Designed to minimize flare and ghosting

From the start of the design process, SIGMA took steps to minimize flare and ghosting and establish an optical design that is resistant to strong incidental light sources such as backlight.

Fast and smooth AF
Stepping motor incorporated for enhanced videography

By incorporating a stepping motor, the lens offers exceptionally quick and quiet autofocusing performance. This feature is especially useful when using the camera to take videos. This lens is also compatible with Sony E-mount Fast Hybrid AF.

Extra-long Hood (Supplied)

The included lens hood is extra-long and features an antireflective coating to manage unwanted light. The hood also features rubber and anti-slip textures to make it easier for the photographer to hold while shooting. Minimum focusing distance of 30cm.

TSC used for a more compact structure and enhanced performance

Since new material Thermally Stable Composite (TSC) is highly elastic, it exhibits minimal deformation. Parts made of TSC are therefore less prone to develop gaps between each other over time. The SIGMA 30mm F1.4 DC DN | Contemporary features a lens barrel and aperture parts made of TSC, which contribute both to the compactness of the lens and the smooth functioning of the aperture system. TSC helps increase the precision of cells holding lens elements and parts related to the focus lens group, further enhancing lens performance.

* Thermally Stable Composite (TSC) offers thermal expansion characteristics similar to those of aluminum. Since parts made with TSC expand and contract less due to changes in temperature, they tend to perform better under extreme conditions and help maintain the performance of the lens. TSC also offers outstanding elasticity.

In the news

The Sigma 30mm f/1.4 is a very good deal if you are looking for a standard lens for the Sony E-mount system. Along with having the fastest aperture of any lens in the E-mount collection, it has a pleasant bokeh and produces sharp results at all the most important apertures.

The good news with the Sigma 30mm f/1.4 is that, when you get the focusing right, you are rewarded with fantastic sharpness. Our real-life images looked as sharp in the centre as they would with a proprietary 50mm f/1.4 DSLR lens. It really is excellent. Reasonable size and weight, excellent image quality, large f/1.4 aperture, superior build quality and a good price all mean that the Sigma 30mm f/1.4 DC DN | C lens is worthy of the consideration of Sony E-mount users. With a retail price of around £300, it is hard to really fault this lens.

You can work at F1.4 with confidence, as the autofocus is fast and accurate and the resolved detail goes to the limit of a AA-free 24 megapixel sensor. By our standards, it certainly matches Art series lenses. The out of focus discs retain a circular look down to F4, only starting to acquire a slight nine-blade shape at F4.5.

A relatively new lens from Sigma’s much-acclaimed Global Vision range, the 30mm f/1.4 prime offers exceptional optical quality, and is the cheapest autofocus lens in test. The 9 rounded diaphragm blades, coupled with the f/1.4 aperture, produce some stunning bokeh in the out-of-focus areas. Sharpness in the corners is extremely impressive, even at the widest aperture.

The built-in stepping motor enables quick and virtually silent autofocussing, with smooth transitions when shooting video. There’s plenty of bite, even at f/1.4, with impressive sharpness and contrast, along with fairly minimal vignetting. Resistance to ghosting and flare in excellent. Overall, this Contemporary class lens performs better than Sigma’s 30mm f/1.4 Art lens for Canon or Nikon cameras.

Sharp images at f/1.4 and edge-to-edge sharpness when the lens is stopped down make this lens very appealing and a useful addition to your collection.
