![]() Its still evolving, but there are plenty of good lenses to use with your L-mount cameracheck. ![]() Meticulous deployment of these types of exclusive low-dispersion glass and optimization of power distribution gives SIGMA lenses superlative image rendition undiminished by residual chromatic aberration. Leica, Panasonic, and Sigma full-frame mirrorless cameras share a common lens system, the L-mount. In particular, FLD glass offers ultra-low dispersion in combination with high transmittance and the anomalous dispersion characteristics of fluorite. Founded in 1961, Sigma Corporation prides itself on high quality and innovative photographic equipment. ![]() To minimize this secondary spectrum, which can be a serious issue with conventional lenses, SIGMA lenses feature up to three types of exclusive low-dispersion glass offering superior performance: ELD (Extraordinary Low Dispersion), SLD (Special Low Dispersion) and FLD (“F” Low Dispersion). Sigma Corporation of America is a subsidiary of the Sigma Corporation, a Japanese based family owned manufacturer of DSLR cameras, camera lenses and camera accessories. Yet residual chromatic aberration known as “secondary spectrum” may still remain. Most chromatic aberration can be removed by combining a high-refractivity convex lens element with a low-refractivity concave element. Found the lens been totally left a side, so decided to. The result is chromatic aberration, the color fringing that is particularly noticeable in telephoto lenses. Bought a Sigma 16mm F1.4 together with the camera which come with the kit lens. This fact causes different colors of light to focus at slightly different points. The degree to which light is refracted by glass depends on the light’s wavelength.
