A member of the high-performance Contemporary line, featuring Sigma's latest technologiesFor 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.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 performanceSince new material Tsc (Thermally Stable Composite) 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.Note: Tsc (Thermally Stable Composite) is a type of polycarbonate with a thermal expansion rate similar to that of aluminum. It has high affinity to metal parts which contributes to high quality product manufacturing.Combining compactness with outstanding optical performanceThe 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.Aspherical lensMount with Dust and Splash Resistant StructureThe mount features a special sealing to make the lens an excellent choice in a wide variety of conditions.Image quality rivaling that of our Art line lensesA 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.
