Created for full-frame Leica L-mount mirrorless cameras. the?Sigma 14-24mm f/2.8 DG DN Art Lens?provides a versatile range of wide-angle focal lengths with excellent image quality while optimizing size and weight.
An Art-series zoom. this lens is also distinguished by its fast f/2.8 constant maximum aperture to suit working in available lighting conditions. Featuring a sophisticated optical design. a series of low dispersion and aspherical elements is used to minimize both chromatic and spherical aberrations throughout the zoom range in order to achieve high sharpness. clarity. and color accuracy. A Super Multi-Layer Coating combined with a Nano Porous Coating also helps to suppress lens flare and ghosting to a greater degree than conventional anti-reflective coatings. This helps to more effectively produce color-accuracy and contrast-rich imagery in a variety of lighting conditions.
Though full-time manual focus is available. this lens is equipped with a stepping motor that enables smooth. high-speed autofocusing that is notably quiet whether utilizing features such as Face/Eye Detection AF or during video shooting. A built-in Autofocus-Lock (AFL) button can be assigned additional functions to widen the range of operations available on the lens. while inside. a rounded 11-blade diaphragm improves image quality by helping to create smooth bokeh. Additionally. a built-in lens hood serves to protect the front element as well as prevent stray light from causing flare.
