Outlet 24mm f/1.4 DG HSM Art Lens (Nikon F-Mount) Wide Angle

The 24mm also excels at indoor   photography in low illumination thanks to the combination of  exceptional  focal plane sharpness, and gorgeous bokeh rendered by nine  rounded  aperture blades. The lens achieves a maximum magnification of  1:5.3 with  a minimum focusing distance of 9.8 inches.

The 24mm   incorporates both “F” Low Dispersion (FLD) glass and Special Low   Dispersion (SLD) glass in a design of 15 elements in 11 groups to   minimize chromatic aberration of magnification especially in the edge of   the image field. Moreover, the optimized power layout includes   aspherical elements that are positioned in the rear of the lens for   improved wide open performance. This helps to ensure minimal distortion   through the correction of axial chromatic aberration and sagittal coma   flare. The new lens element design also delivers excellent peripheral   brightness.

Other updates to this lens include a   new full-time manual focusing mechanism that switches to manual   focusing, simply by rotating the focus ring, even when AF is being used,   first introduced on the 50mm Art. This allows the photographer to make   focus adjustments quickly and easily. As with all new lenses under the   Global Vision categories, every 24mm will be tested using Sigma’s own   MTF measuring system, “A1,” in the company’s factory in Japan.
