Sigma is a Japanese based family owned manufacturer of DSLR cameras, camera lenses and camera accessories. Liked by everyone is that Sigma lenses are typically value-priced. Sigma lenses are available in Canon, Nikon and other brands.
The lens integrates three aspherical elements into its construction as well as two SLD and two FLD glass elements to help minimize aberration, field curvature, and distortions throughout the zoom range as well as provide greater image sharpness while avoiding reduced peripheral brightness. Super Multi-Layer Coating has also been applied to lens elements to reduce surface reflections, lens flare, and ghosting to produce images with higher contrast and color fidelity.
