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.

1. 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.

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

Image quality rivaling that of our Art line lenses
 

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.

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.

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.

 

 

 

 

 

3. 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.

TSC used for a more compact structure and enhanced performance
 

Thermally Stable Composite (TSC)

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. As compared to polycarbonate containing 20% glass, TSC offers approximately 70% higher elasticity. As compared to polycarbonate containing 30% glass, it offers 25% higher elasticity. (Comparison is between SIGMA-produced components.)

Evaluation with SIGMA’s own MTF measuring system: A1
 

46-megapixel Foveon direct image sensor

46-megapixel Foveon direct image sensor

We used to measure lens performance with a Modulation Transfer Function (MTF) measuring system using conventional sensors. However, we have developed our own proprietary MTF measuring system (A1)* using 46-megapixel Foveon direct image sensors. Even previously undetectable high-frequency details are now within the scope of our quality control inspections. All SIGMA 30mm F1.4 DC DN | Contemporary lenses are checked using this A1 system before they are shipped.
