Combining outstanding optical performance and compact design Introducing a new F1.4 standard lens for mirrorless cameras
Captured with the SIGMA 30mm F1.4 DC DN | Contemporary lens in EF-M mount by Paul Bonito-Brook
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, 45mm on the Sony E-mount system and 48mm on the Canon EOS M system.

Diffraction MTFThere are two types of MTF chart. One considers the diffraction quality of light, which is called “Diffraction MTF”, and the other, “Geometrical MTF” does not. The quality of light appears in the diffracted light, and becomes more distinct as the F value gets bigger, resulting in lower image quality. Also, diffracted light exists at every aperture, which is why SIGMA has been releasing Diffraction MTF data from the beginning since it is very close to the actual image data. The readings at 10 lines per millimeter measure the lens’s contrast ability (red lines), repeating fine parallel lines spaced at 30 lines per millimeter measure the lens’s sharpness ability (green lines), when the aperture is wide open. | Geometrical MTFThe advantage of using “Geometric MTF” data is that it is easy to measure and calculate since it does not consider the diffraction quality of light, yet it tends to show higher values in the graph than actual images. The readings at 10 lines per millimeter measure the lens’s contrast ability (red lines), repeating fine parallel lines spaced at 30 lines per millimeter measure the lens’s sharpness ability (green lines), when the aperture is wide open. | Supplied AccessoriesLENS HOOD LH586-01 FRONT CAP LCF Ⅲ 52mm REAR CAP LCR Ⅱ *The lens hood cuts harmful rays that can negatively affect photographs while also minimizing reflectivity within the hood itself. The hood also features a rubber construction and a non-slip groove to make it easy to hold in a variety of shooting situations. | Made in JapanAll Sigma products, lenses, cameras and flash units are manufactured exclusively by Sigma in Sigma’s own factory in Aizu, Japan. No Sigma Corporation product – lens, camera or flash – is manufactured outside of Japan. This is very unusual these days, as most companies have at least some of their products produced outside of Japan because of cost considerations. There's a reason why SIGMA continues to insist on the very highest quality in its product manufacturing: our love of photography is second to none. We deeply appreciate the photographer's desire to record and express—the passion of the photographer. We understand the need to capture the moment that gives rise to a unique work |
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.
Designed to minimize flare and ghosting with a rounded diaphragm creates an attractive blur.
The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.
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.
TSC used for a more compact structure and enhanced performance
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.
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.
