At home under the Art category, this high-performance standard lens is designed exclusively for mirrorless interchangeable lens cameras and has the equivalent angle of view as 120mm on the Micro Four Thirds system. This lens features SLD (Special Low Dispersion) glass, which helps minimize axial and transverse chromatic aberration. Glass mold aspherical lenses help minimize coma. Optimized power distribution helps ensure exceptional image quality from the center to the edges of the images. In addition, the inner focusing system corrects the fluctuation of aberration to maintain image quality regardless of the focusing position. The superior telecentric optical design improves the image quality throughout the frame. The optical design also allows the lens to be compact and lightweight. This lens benefits from a newly developed linear AF motor, which moves the lens elements directly without the need for gears or the drive of other mechanical parts. This system ensures accurate and quiet autofocusing, making the lens suitable for video recording as well as still photos. The lens features a rounded 7-blade diaphragm creating an attractive blur to the out of focus areas of the image. This Sigma 60mm F2.8 DN has a minimum focusing distance of 50cm/19.7in and a maximum magnification ratio of 1:7.2, and comes in a black finish.
Mirrorless interchangeable lens cameras (MILCs) are popular because of their compact bodies, ease of operation and portability. Featuring superior optical performance and functionality that responds to the requirements of the photographer, the DN series of lenses for mirrorless interchangeable lens cameras offers SIGMA's original innovation in a form that is more polished and refined than ever before. Exemplifying the characteristics of the Art line, the new members of the DN series are a standard lens, a wide-angle lens and a mid-range telephoto lens that is a completely new entry in the series. These lenses represent a new world of possibilities, helping photographers find the deeper essence of their art and increase their opportunities to express themselves.
Designed with a focus on sophisticated optical performance and tremendous expressive power, our new Art line of lenses delivers top-level image quality. With unsurpassed expressive performance, these lenses reach the high standards demanded by photographers with an artistic, creative inclination. Along with landscapes, portraits, still-life, close-up and casual snaps, they're perfect for the kind of photography that unleashes the inner artist. Ideal for studio photography, they offer just as much expressive scope when capturing architecture, starry skies, underwater shots and many other scenes.
This high-performance mid-range telephoto lens offers an angle of view of equivalent to 120mm on the Micro Four Thirds system and 90mm on the E-mount system (35mm equivalent focal length). Featuring a natural feeling of perspective and beautiful bokeh effects, this lens allows the photographer to zoom in on distant objects and capture a single part of a subject. It brilliantly realizes the photographer's intentions. With a minimum focusing distance of 50cm and a maximum magnification ratio of 1:7.2, this lens is excellent for taking shots with a pinpoint focus on a subject. Currently comprising the SIGMA 60mm F2.8 DN｜Art mid-range telephoto lens, the SIGMA 30mm F2.8 DN｜Art standard lens and the SIGMA 19mm F2.8 DN｜Art wide-angle lens, the updated DN series expands photographers' high-performance options for mirrorless interchangeable lens cameras.
This lens features SLD (Special Low Dispersion) glass, which helps minimize axial and transverse chromatic aberration. Glass mold aspherical lenses help minimize coma.

In addition, the inner focusing system corrects the fluctuation of aberration to maintain image quality regardless of the focusing position. The superior telecentric optical design improves the image quality throughout the frame.
The degree to which light is refracted by glass depends on the light's wavelength. This fact causes different colors of light to focus at slightly different points. The result is chromatic aberration, the color fringing that is particularly noticeable in telephoto lenses. Most chromatic aberration can be removed by combining a high-refractivity convex lens element with a low-refractivity concave element. Yet residual chromatic aberration known as “secondary spectrum” may still remain. To minimize this secondary spectrum, which can be a serious issue with conventional lenses, SIGMA lenses feature up to three types of exclusive low-dispersion glass offering superior performance: ELD (Extraordinary Low Dispersion), SLD (Special Low Dispersion) and FLD (“F” Low Dispersion). In particular, FLD glass offers ultra-low dispersion in combination with high transmittance and the anomalous dispersion characteristics of fluorite. Meticulous deployment of these types of exclusive low-dispersion glass and optimization of power distribution gives SIGMA lenses superlative image rendition undiminished by residual chromatic aberration.
There are three requirements for outstanding lenses: fine design, precise manufacturing and inspection that ensures compliance with all specifications. SIGMA lenses are born of well-thought-out design concepts and sophisticated, advanced Japanese manufacturing technology; the final clincher is our lens performance evaluation. We used to measure lens performance using conventional sensors. However, we've now developed our own A1* proprietary MTF (modulation transfer function) measuring system using 46-megapixel Foveon direct image sensors. Applying this system, we check each lens in our new lines at our Aizu factory, our sole production site. Even previously undetectable high-frequency details are now within the scope of our quality control inspections, allowing us to deliver consistently high lens performance.
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.
Optimizing quality with our integrated production system, SIGMA is focused on making things right, with our own hands and our own techniques. We are now one of the very few manufacturers whose products are solely "made in Japan." We like to think our products are somehow imbued with the essence of our homeland, blessed as it is with clean air and water, and focused, hard-working people. We pride ourselves on the authentic quality of SIGMA products, born of a marriage between highly attuned expertise and intelligent, advanced technology. Our sophisticated products have satisfied professionals and lovers of photography all over the world, because our manufacturing is based on genuine craftsmanship, underpinned by the passion and pride of our experts.
The simple shape of the focus ring, varying textures that distinguish each part of the lens, the elegantly etched product name, the use of metal on almost all external areas of the lens, the unibody design of the hood—all of these elements add up to a lens design that is ideal for mirrorless interchangeable lens cameras. In addition, photographers have the choice of black or silver to match their favorite equipment. The basic concept, however, is no different from that of other SIGMA lenses: responding intuitively to the photographer's intentions and performing fundamental functions at the highest level possible. The interior of the lens features a quiet and powerful linear motor, while the brass mount combines high precision with durability. Designed for use over the long term, this lens features treated surfaces, enhanced strength and overall construction of the highest quality.
This lens benefits from a linear AF motor which moves the lens unit directly without the need for gears or other extra mechanical parts. This system ensures accurate and quiet autofocusing, making the lens excellent for both recording video and taking still photos.
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.
