![]() (Comparison is between SIGMA-produced components. As compared to polycarbonate containing 30% glass, it offers 25% higher elasticity. Designed as a ‘standard prime’ for APS-C format DSLRs, this Sigma delivers an entirely natural viewing perspective, along with a fast f/1.4 aperture that enables fast shutter speeds under low lighting conditions and a tight depth of field. As compared to polycarbonate containing 20% glass, TSC offers approximately 70% higher elasticity. Since parts made with TSC expand and contract less due to changes in temperature, they tend to perform better under extreme conditions and help maintain the performance of the lens. Its one of the rare SLR lenses in this focal range thats dedicated to that sensor format, and the only. Lens Hood Size (DxL), 3.54 x 1.57 (90 x 39.8mm) Lens Length with Hood (Min-Max), 4.2 - 4.2 (106.6 - 106.6mm) Size of Rings: Focus / Zoom, 0.55 (13.9mm). ![]() * Thermally Stable Composite (TSC) offers thermal expansion characteristics similar to those of aluminum. The Sigma 30mm F1.4 DC HSM Art (499) is a standard-angle prime lens for APS-C cameras. TSC helps increase the precision of cells holding lens elements and parts related to the focus lens group, further enhancing lens performance. 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. Parts made of TSC are therefore less prone to develop gaps between each other over time. Vignetting will occur if the lens is used with digital cameras with image sensor larger than APS-C size or 35mm SLR, and APS Film SLR cameras. The Sigma 30mm F1.4 DC DN Contemporary lens is a fixed maximum aperture standard prime lens for Sony E, Micro Four-Thirds, Canon EF-M, and Leica L mounts, announced by Sigma in February 2016. 00-85126-30060-9 (SIGMA 30mm F1.4 EX DC) All figures calculated by SIGMA SA-mount. Low levels of distortion enable it to be used for. 00-85126-30034-0 (SIGMA 30mm F1.4 EX DC) Pentax Mount. Since new material Thermally Stable Composite (TSC) is highly elastic, it exhibits minimal deformation. The fast maximum aperture makes it usable for portraiture as well as wedding and event photography.
