Sigma Contemporary AF

30mm f/1.4 DC DN Lens for Sony E-Mount (Black)

A new large-aperture F1.4 standard lens from the Contemporary line

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 and 45mm on the Sony E-mount system.

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 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.

Image quality rivaling that of Sigma's Art line lenses

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

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 transverse 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 Sigma's Art line lenses.

 

Designed to minimize flare and ghosting

From an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. SIGMA’s Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions. The included lens hood can be attached to block out extraneous light, which can have a negative effect on rendering performance.

 

 

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.

 

 

 

 

 

New SIGMA Global Vision product lines are setting new benchmarks for image quality

Evaluation with SIGMA's own MTF measuring system: A1

Sigma used to measure lens performance with a Modulation Transfer Function (MTF) measuring system using conventional sensors. However, they have developed their 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 their quality control inspections. All SIGMA 30mm F1.4 DC DN | Contemporary lenses are checked using this A1 system before they are shipped.

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.

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.

46-megapixel Foveon direct image sensor

The 46 effective megapixel (4,800 × 3,200 × 3 layers) and 44 recording megapixel (4,704 × 3,136 × 3 layers) 23.5 × 15.7mm APS-C X3 direct image sensor captures all primary RGB colors at each and every pixel location, ensuring the capture of full and complete color. Using three silicon-embedded layers of photo detectors, stacked vertically to take advantage of silicon's ability to absorb red, green and blue light at different respective depths, it efficiently reproduces color more accurately, and offers sharper resolution, pixel for pixel, than any conventional image sensor. Since color moiré is not generated, the use of a low-pass filter is not required, meaning light and color, generated by the 46-megapixel APS-C X3 direct image sensor is captured with a three-dimensional feel.

  • 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.
  • High-precision, rugged brass bayonet mount

    The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.
  • 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.
  • Rounded diaphragm

    The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.
