SIGMA 30/1.4 DN DC CONTEMPORARY P/FUJI-X

In addition to optimised design and power distribution, this lens incorporates an aspherical and a double aspherical element, as well as a high refractive index, high dispersion glass element with high anomalous partial dispersion. By making effective use of these technologies, the lens offers excellent brightness right to the edges of the image and minimises transverse chromatic aberration. To correct distortion, the lens takes advantage of the mirrorless camera body's image correction, using the correction power of the optical system to improve sharpness. The end result is an extremely compact lens that delivers image quality rivalling that of our Art line lenses."

The SIGMA 30mm F1.4 DC DN | Contemporary features TSC barrel and aperture parts, which contribute to both the compact size of the lens and the smooth operation of the aperture system. TSC helps to increase the precision of the cells that hold the lens elements and related parts of the focusing lens group, further improving lens performance. *Thermally Stable Composite (TSC) is a material that offers thermal expansion characteristics similar to those of aluminium. Because parts made with TSC expand and contract less due to temperature changes, they help maintain lens performance. TSC also offers exceptional elasticity. Compared to polycarbonate containing 20% glass, TSC offers approximately 70% more elasticity. Compared to polycarbonate containing 30% glass, TSC offers approximately 25% more elasticity.

For optimal light balance with compact camera bodies with a short rear focal length, SIGMA has designed the new SIGMA 30mm F1.4 DC DN | Contemporary lens to be extremely compact. In addition, it features SIGMA's inner focusing technology and lighter elements in the focusing lens group, enabling a more compact final size that is useful for shooting video. Structurally, the lens incorporates materials and parts that contribute to its compact size and light weight. In short, this is an unprecedented lens that combines exceptional optical performance with excellent portability and ease of handling.
