8/24/2023 0 Comments Sigma 30mm 1.4 canon![]() (Comparison is between SIGMA-produced components. As compared to polycarbonate containing 30% glass, it offers 25% higher elasticity. The rubber grooves are deep, sticky, better than some Ls. The new lens has an optical configurations of nine elements in eight groups, including a double-aspheric element, with. On APS-C cameras this lens covers an effective focal length of approximately 45mm, making it a very useful standard focal length. el día : Es un objetivo que me da mucho juego, para las fotos que yo hago, de paisaje y algún macro, me funciona muy bien. As compared to polycarbonate containing 20% glass, TSC offers approximately 70% higher elasticity. Its tough but smooth, years ahead of any intermediary Canon. The Sigma 30mm F1.4 EX DC HSM lens is a redesigned version of Sigma's popular 30mm F1.4 prime. TSC helps increase the precision of cells holding lens elements and parts related to the focus lens group, further enhancing lens performance. 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. 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. 339 30mm F1.4 DC DN C 339 SKU: 302 Designed for crop sensor mirrorless Classic standard focal length Ultra-fast F1. ![]() * Thermally Stable Composite (TSC) offers thermal expansion characteristics similar to those of aluminum. 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. Since new material Thermally Stable Composite (TSC) is highly elastic, it exhibits minimal deformation.
