Sigma 28mm f1.8 EX DG ASP Macro


Description

For many photographers, the 28mm focal length is the ideal general purpose wide angle lens. Its wide enough for most scenic and landscape assignments and when used indoors for building interiors or groups of people, its wide angle effect is not as extreme as with shorter focal length lenses. A forgiving wide angle lens for newcomers to wide angle photography and highly effective for professionals with its EX construction and fast 1.8 aperture. This high speed performance is excellent for photojournalists doing low-light documentary photography and its use of two aspherical lens elements assures excellent optical performance.
