Information of Sigma 150-600mm f/5-6.3 DG Contemporary Lens for canon

 

Overview

Minimized transverse chromatic aberration—thanks to FLD and SLD glass lens elements.

This lens features one FLD Glass element, which offers performance equivalent to fluorite, and three SLD (Special Low Dispersion) glass elements to minimize chromatic aberration. In particular, the low-dispersion glass elements and optimized power distribution help minimize transverse chromatic aberration, which can tend to affect the telephoto end and cannot be reduced by adjusting focus. The end result is outstanding image quality throughout the zoom range.

 

Flare and ghosting reduction

From 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.

 

Exclusive low-dispersion glass

The degree to which light is refracted by glass depends on the light’s wavelength. This fact causes different colors of light to focus at slightly different points. The result is chromatic aberration, the color fringing that is particularly noticeable in telephoto lenses. Most chromatic aberration can be removed by combining a high-refractivity convex lens element with a low-refractivity concave element. Yet residual chromatic aberration known as “secondary spectrum” may still remain. 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). In particular, FLD glass offers ultra-low dispersion in combination with high transmittance and the anomalous dispersion characteristics of fluorite. 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.

 

Rounded diaphragm

When photographing with point light sources such as electric lights or reflections on a body of water in the background, the rounded 9-blade diaphragm helps produce an attractive bokeh effect—even at large-aperture settings.
