Sigma 30mm F1.4 DC DN | C MILC Standard lens Black

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.TSC used for a more compact structure and enhanced performanceSince the 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.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.Mount with Dust and Splash Resistant StructureThe mount features a special sealing* to make the lens an excellent choice in a wide variety of conditions.* L-Mount onlyImage quality rivaling that of our Art line lensesIn 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 our Art line lenses.* Limited to what the camera supports.Designed to minimize flare and ghostingFrom 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 effectThe 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.High-precision. rugged brass bayonet mountThe brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.Rounded diaphragmThe 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.
