The lens construction consists of 17 elements in 12 groups, including three low-dispersed fluorite-like FLD glass elements, two low-dispersed SLD glass elements, one aspherical element and a large-diameter front lens. The optical design effectively minimizes distortion, chromatic aberration and sagittal coma, and the 9-blade rounded aperture allows for a beautiful bokeh pattern. This makes the Sigma Art 105mm the ideal tool for astrophotography and portraits.

The lens has a maximum angle of view of 23.3° for 35 mm , minimum focus distance 100 cm, 105 mm filter thread diameter, maximum magnification factor 1:8.3 and a minimum aperture of F16.

The lens features a floating two-group focusing system that effectively compensates for astigmatic and spherical aberration, ensuring high image quality from infinity to 1:1 macro. The lens construction consists of 13 elements in 10 groups, including two low-dispersion elements of fluorite-like FLD glass, two low-dispersion elements of SLD glass, two aspherical elements and one element with high partial dispersion and high refractive index.

Other features include: 9-blade rounded aperture, maximum aperture angle of 34.3 degrees for 35 mm , minimum focusing distance of 25.8 cm, maximum magnification ratio of 1:1, filter diameter of 49 mm, minimum aperture of F22. At 515g, the lenses are 105.8mm long and 70.8mm in diameter.

Both manual and auto focus are available on the lens. Manual focus adjustment uses ‘focus-by-wire’ technology where the adjustment ring activates an electronic motor which is responsible for moving the lens. There is also a three-position switch on the lens body, allowing you to select the focus limits.

Ready for any challenge

In addition to their outstanding optical performance, both lenses boast enhanced environmental protection, making them suitable for extreme conditions. The magnesium alloy lens barrel is protected against water and dust by a special seal on the lens mount and adjustment rings. The front lens also has a special coating that effectively combats dirt, dust, oil stains and water droplets.
